Microscopy

Analyte

Solid systems;
Composites, materials, organic and inorganic substances, thin layers

Equipment

• Device: JEM-1400Plus (Jeol), accelerating voltage up to 200 kV, digital image recording and filing

Evaluation methods and targets

• Image analysis by image processing software (Olympus GmbH, Germany): determination of particle sizes and their distribution
• Morphology of cross-sections and surfaces with a resolution of up to 10 nm
• Identification of morphological structures in materials from natural and synthetic polymers
• Investigation of structure-property-correlations depending on production and growth parameters, respectively, particularly natural polymers

Application examples

• Ultra thin cross-section of a viscose fiber: core-shell structure with pores (→ Image gallery)
• Surface mark of pulp: fibrillation of the primary wall (→ Image gallery)
• Exfoliation of nanoclays in polymeric matrix
