Converting PBO fibers into carbon fibers by ultrafast carbonization

Carbon, 2020
Abstract We report an ultrafast transformation of poly(p-phenylene-2,6-benzobisoxazole) (PBO) fibers into carbon fibers (CFs) by direct carbonization that eliminates high-cost oxidation in traditional CF conversion. Ultrafast heating and cooling render PBO-derived CFs superlative mechanical properties.
