Carbon Fiber from Direct Carbonization of Pedot:Pss Precursor Fibers

Carbon Trends
An important factor limiting widespread carbon fiber utilization is the immense energy required for its manufacture. Specifically, the pre-carbonization stabilization processing step required for polyacrylonitrile and pitch fiber precursors accounts for a large portion of the total processing time and embodied energy associated with carbon fiber ...
