1. Computational studies of Poly(vinylidene fluoride) and Poly(vinylidene fluoride) - Single Wall Carbon Nanotube Composites
Sammanfattning : Poly(vinylidene fluoride) (PVDF) exhibits properties that allows the material to be used in such diverse areas as wire and cable products, electronic devices, membranes, exterior coatings for constructions and in the chemical, pharmaceutical and food industry as fluid-handling equipment. It is the inherent molecular structure of PVDF, where every second backbone carbon is bonded to two fluorine atoms, that gives the polymer several unique properties, among them piezo- and pyroelectricity.

4. Melt spinning of poly(vinylidene fluoride) mono- and bicomponent fibres and yarns - the formation of piezoelectric beta-phase crystallinity
Sammanfattning : .... LÄS MER
Sammanfattning : Non-linear characteristics of homogeneous solid polymers and solid polymer-based composites have been studied both experimentally and theoretically. In particular experimental studies of non-linear dielectric response of six homogeneous solid polymeric materials and the influence of the composition on the properties of solid polymer-based composites with high dielectric permittivities have been carried out and a theoretical study of dipole-dipole interaction in solids based on a formulation due to P.
