Ultrafine fibers on the basis of biopolymer polyhydroxybutyrate (PHB) modified with nanosized modifications of titanium dioxide

Abstract

The technological characteristics of spinning polymer solutions (viscosity, conductivity) and the parameters of the EPI - a process based on poly-3-hydroxybutyrate modified with nanoscale titanium dioxide were optimized. The composite materials were studied by X-ray diffraction, differential scanning calorimetry, infrared spectroscopy and physico-mechanical analysis (tensile test, elongation). A significant improvement in their physical and mechanical properties (breaking length, elongation) and resistance to the maturing were found.
