Polymers play an important role in materials science, because of their advantages over other types of materials. The huge variety in terms of the types, arrangements and combinations of monomers found in polymers leads to an extremely wide diversity of different polymeric materials. Although there is a wide range of analytical techniques to characterize polymeric materials, here the focus is laid...
The fracture behavior and fracture mechanics at the very early stages of both ethylene-propylene-rubber (EPR) and linear low-density polyethylene (LLDPE) modified isotactic polypropylene (iPP) were investigated. For this purpose tensile tests of the respective samples were stopped at forces far below the yield point and subsequently 3D reconstructions of the fracture regions were performed. It was...
For the first time, a multiplanar photonic crystal structure has been obtained using cellulose as a structural material. This all-polymer system, made of cellulose, polyvinyl alcohol and poly(N-vinylcarbazole) is a ternary planar photonic crystal composed by 7 repeated trilayers produced by spin coating. Trimethylsilyl cellulose is used as a precursor to be converted to cellulose. Transverse Transmission...
Atomic force microscopy in liquid environments (L-AFM) became a state of the art technique in the field of enzymatic cellulose degradation due to its capability of in situ investigations on enzymatic relevant scales. Current investigations are however limited to few substrates like valonia cellulose, cotton linters and processed amorphous cellulose as only these show required flatness and purity....
