实现电子器件与纺织品整合以开发具有多种功能（比如具有统一的能量存储和利用能力的纤维）的智能可穿戴功能性服装的最佳方法，是近期备受关注的重要课题。因此，提出一种在连续过程中获取具有此类独特性能的纤维的简便方法，是朝着该领域发展迈出的积极贡献性的一步。在此，我们提出了一种自下而上的方法来制备具有独特有机蒸汽传感行为的可拉伸聚苯乙烯 - 丁二烯 - 聚苯乙烯/少层石墨烯复合（SBS - G）纤维，以及通过改良的静电纺丝制备涂覆有电活性炭黑（CB）纳米纤维且具有优异储能性能的改性SBS - G纤维。与仅对极性或非/低极性有机蒸汽有响应的传统导电聚合物复合材料（CPCs）不同，所制备的SBS - G复合纤维对极性和非/低极性有机蒸汽均表现出高灵敏度、优异的可逆性和重现性以及快速响应。此外，基于改性纳米纤维的SBS - G纤维展现出高电容性能（78 F/cm³）、能量和功率密度（6.6 mW·h/cm³和692 mW/cm³）以及优异的柔韧性。这项研究为基于聚合物复合纤维制造理想的有机蒸汽传感器提供了指导方针，并为基于纤维的储能对任何“现成纤维”进行改性提供了一种方法。
Realizing the best way to integrate electronics and textiles to develop smart wearable, functional apparel with multiple functionalities such as fibers with a unified capability to store and utilize energy is a significant topic of concern recently. Therefore, presenting a facile approach to obtain fibers with such unique properties in a continuous process is a forward contributing step towards the development of this field. Herein, a bottom-up approach to fabricate stretchable poly(styrene-butadiene-styrene)/few-layer graphene composite (SBS-G) fibers with unique organic vapor sensing behaviors and modified SBS-G fibers coated with electroactive carbon black (CB) nanofibers via modified electrospinning with excellent energy storage properties is presented. Unlike conventional conductive polymer composites (CPCs) that respond only to polar or non/low-polar organic vapors, the fabricated SBS-G composite fibers exhibited high sensitivity, excellent reversibility, and reproducibility as well as fast response to both polar and non/low-polar organic vapors. Moreover, the modified nanofiber-based SBS-G fibers demonstrated a high capacitive performance (78 F cm−3), energy and power density (6.6 mW h cm3 and 692 mW cm3) and excellent flexibility. This study provides guidelines for the fabrication of ideal organic vapor sensors based on polymer composite fibers and an approach to modify any “off-the-shelf fiber” for fiber-based power storage.
