Electrothermal Transformations of Polyoxadiazole Fibers during Carbonization

The effects of heating and carbonization regimes on the properties of poly(p-phenylene-1,3,4- oxadiazole) fibers and carbon fibers made from them were studied using x-ray, thermal, electrothermal, and mass-spectrometric analyses. Structural transformations that changed the fiber system state were re...

Description
Summary:The effects of heating and carbonization regimes on the properties of poly(p-phenylene-1,3,4- oxadiazole) fibers and carbon fibers made from them were studied using x-ray, thermal, electrothermal, and mass-spectrometric analyses. Structural transformations that changed the fiber system state were responsible for the electrothermal transformations in the polymeric fiber during heat treatment in the low-temperature range up to 400°C
