The Fraunhofer IAP has developed rapidly in 30 years. Here we tell you where we come from and where we are going.

The Fraunhofer IAP turns THIRTY. What will the next 30 years bring?

What contribution do composites make to the energy turnaround?

Lightweight design systems will benefit decisively from the increasing use of composites in the future and thus make an important contribution to completing the energy and mobility turnaround. Due to their low mass, combined with their high strength and stiffness properties and enormous design freedom, they are ideally suited to the production of particularly energy efficient structures with a high functional density. For example, it is comparatively easy to integrate additional optical and electronic functions in the components and thus implement systemic concepts. Holistic developments, which must above all include recovery and recycling strategies for end-of-life scenarios, will enable more sustainable products in the fields of energy technology, mobility and mechanical engineering. The global megatrends of digitalization and artificial intelligence, decarbonization and biologization of technology will further drive these developments and spur the establishment of a stringent sustainable circular economy.

What role do plastics play in a sustainable circular economy?

Life without plastics is hardly conceivable today. They make our lives more comfortable and safer. But large quantities end up in the trash or are incinerated. Only a small proportion is reused as recyclate in the production of new plastic products.
In the future, plastics will be obtained from non-fossil sources such as biomass or CO₂ in a sustainable circular economy. They will be perceived and treated as valuable by consumers and industry. When they have fulfilled their purpose in a “life“, they will be collected by type in digitized deposit and sorting systems. From this “waste“, next-generation processing plants will extract raw materials that are used to produce new plastic products The circle is closed.

How do we manage water as a resource sustainably?

At first glance, there is plenty of water in Germany. In the course of climate change, however, there have been long periods of drought in recent years. Soils have dried out, forests have been stressed by the dryness, and trees have died. Therefore, we need to adapt the future use and purification of water. Conventional optimization strategies that are mainly focused on the reduction of the cost of water purification will not be sufficient. The resource water must be thought of as a whole. For example, limits for water pollution must be tightened and wastewater must be understood in the future as a source for the recovery of valuable substances and energy. At Fraunhofer IAP, we are actively contributing to the transformation of water purification: We develop new membranes for sustainable and targeted recovery of water and valuable substances such as nitrates and phosphates for reuse in agriculture.

How do textiles become more sustainable?

Sustainability in the textile industry is becoming increasingly important and is demanded by the market. Cellulosic man-made fibers such as viscose or lyocell fulfill precisely these requirements and can thus hold their own against other synthetic man-made fibers. Currently, various alternative processes for the production of cellulosic fibers are on a pilot scale, in which the Fraunhofer IAP is involved as a development partner. I am convinced that in 30 years a European cellulosic staple fiber will be established on the market, in the development of which the Fraunhofer IAP was significantly involved.

How do we replace fossil fuels with hydrogen?

Hydrogen will be a central component of the energy transition and decisively drive the decarbonization of society and industry. The production of hydrogen by electrolysis on a large scale, and also its use as a raw material in chemical processes or for electricity generation in fuel cells, requires more efficient catalysts with smaller amounts of rare and therefore expensive precious metals such as platinum or iridium compared to today.
At Fraunhofer IAP, we are developing and testing more robust, long-lasting catalysts with the smallest possible amounts of precious metals, which are already comparable in performance to common commercial materials. So that we will still be able to see the light in thirty years' time.

How can we make solar energy more sustainable?

In the European "Green Deal", the reduction of CO₂ emissions is a central goal. To achieve this, energy generation should be as resource-efficient as possible, using sun and wind. However, the production of already established silicon-based solar cells requires a high energy input and the use of critical raw materials. The Fraunhofer IAP is working on an alternative with partners from industry and research in Europe. They are producing printed solar cells based on organic and inorganic-organic raw materials. Such polymer and hybrid materials allow the application of efficient printing technologies that can produce solar cells with a significantly lower carbon footprint. The challenge here is to accomplish a lifetime and performance comparable to conventional systems. Successes have already been achieved on a laboratory scale. Scaling up to processes suitable for industrial use is the task we will be tackling at Fraunhofer IAP in the coming years.

Inspired by nature – does the car tire of tomorrow look like this?

Natural rubber from rubber trees, with its excellent abrasion properties, is very well suited for the extremely durable treads of truck tires. But the use of the natural raw material brings problems with it: fungal infestations of rubber trees endanger their existence, and its cultivation areas are severely limited by the climatic conditions required. Both of these factors limit the security of supply. Synthetically produced rubber has so far failed to match its natural counterpart in terms of abrasion behavior. We therefore set ourselves the challenge of understanding the fundamentals of the unique mechanical properties of natural rubber and transferring them to a synthetic product. The result is Biomimetic Synthetic Rubber "BISYKA", which even surpasses the properties of natural rubber. Tires based on "BISYKA" show 30 % less abrasion as well as better rolling resistance than conventional products. The use of Big Data technologies, artificial intelligence as well as energy-efficient synthesis processes will advance the optimization and further development of "BISYKA" rubber in the future. Our goal at the Fraunhofer IAP: to get a car tire rolling with less abrasion and thus reduce the distribution of microplastics into the environment.

How can functional polymers contribute to prevent climate change?

To achieve climate targets, an energy transition is essential. "Green hydrogen", produced by the electrolysis of water and using renewable energy sources, plays a crucial role as a sustainable energy carrier. However, this requires optimization of previously used systems for the production and use of hydrogen. New tailor-made membranes, which are an important component of electrolysis and fuel cells, show great potential in terms of performance, cost-effectiveness and sustainability. In the field of proton-conductive membranes, we have already developed a polymer that exhibits conductivity comparable to commercial products (e.g. Nafion 212 ®), while being more environmentally friendly and cost-effective. With the development of new functional polymers, we are making a significant contribution to the technologies of the energy transition and thus to achieving the climate targets. Today and in 30 years.

How can 3D printing help patients through personalized medicine?

Personalized medicine has the potential to revolutionize the healthcare sector. Therapies will no longer follow uniform designs, but will be individually tailored for patients. Modern 3D printing technologies are part of this paradigm shift. They enable the production of for example heart valves, cardiac assist devices, artificial bones, tissue scaffolds, eyeglasses and even drugs that vary in shape, size, mechanical strength, biodegradability and drug release profile to meet the specific needs of patients. Here, the materials used for 3D printing play a key role. However, their performance is often still inadequate, necessitating further material developments. With novel polymers for artificial pericardial tissues, for example, we print precisely fitting implants that meet the mechanical requirements of a pericardium. We are convinced: New printable materials will help patients in the future through personalized medicine.

What can microcapsules contribute to the energy transition and circular economy?

It's the inner values that count, but they have to be well packaged. What sounds like an empty phrase describes the technology of microencapsulation very well. Here, active ingredients are packaged in a protective shell, which enables a wide range of applications. Whether as a lubricant, biocide, adhesive, food additive, fragrance or latent heat storage, the range of applications for encapsulated materials covers almost all areas of life.
Microcapsules are used as additives to give a material new functions. For example, microcapsules filled with liquid lubricant can be incorporated into plastic-based components directly during production. This results in an extension of service life through wear protection as well as a reduction in energy consumption when using such components. Biologically active microcapsules containing microorganisms and other biological materials while retaining their properties are also being developed. A future application for this could be the recovery of raw materials from wastewater by encapsulated biomineralizing bacteria to enable sustainable recycle streams.  And to reduce the input of microplastics into the environment, the microcapsules will be biodegradable after they have fulfilled their function.

Will in-vitro tests optimize the development of new substances and biomaterials in the future?

How active substances work and whether biomaterials are safe for humans can be tested in different ways. One approach are novel in-vitro tests – analyzes that take place in a test tube. For this purpose, we use human cells obtained from tissue and investigate their interaction with substances under artificial conditions. At the Fraunhofer IAP, we thus collect comprehensive information on efficacy, toxicity and deeper mechanisms, such as the effect on the immune system, the release of active substances or the appearance of inflammatory foci. In-vitro testing thus ensures a comprehensive and realistic analysis of the biocompatibility of polymers and drugs and active substances.

The close cooperation between chemistry, biology, veterinary medicine and the clinic also promotes the development and evaluation of new products. And, results from the laboratory are transferred to the clinic faster, more cost-effectively and with great patient safety. As a further prospect, the development of new in-vitro models will significantly reduce the number of necessary animal experiments in the coming years.
