采用真空碳化法直接制备了氮、硫共掺杂的柔性、高导电、高强度的石墨中空碳纤维。通过将这些具有成本效益的CF与聚丁二炔（PDA）一起工程化，成功地创建了一种新的超灵敏可逆电致变色纤维家族，其在暴露于电流和UV光刺激时显示可切换的颜色过渡（蓝色和红色）。
Flexible, highly conductive, robust nitrogen (N), sulfur (S) co-doped graphitic hollow carbon fibers (CFs) were directly fabricated by vacuum carbonization of "human hairs". By engineering these cost-effective CFs with polydiacetylene (PDA), a new family of ultrasensitive, reversible electrochromatic fibers that display switchable color transition (blue ⇋ red) upon exposure to current and UV-light stimuli was successfully created.
