Fabrication of Porous Carbon Nanofibers with Large Power Handling Capability

摘要

A method for producing porous nanofibers having tunable meso- and micropores, and the articles produced by the method. In some embodiments, the method comprises electrospinning a polymer blend comprising polyacrylonitrile and a sulfonated polymer dissolved in a solvent to form a fibers; heat treating the mat or web of fibers sequentially at first, second, and optionally third temperatures; and optionally treating the heat treated fibers with an oxidizing agent.
