摘　　要：多功能集成纤维电极的批量化制备是实现纤维或织物类柔性电子器件大面积穿戴应用的基础.研究基于高分子半导体材料的柔性、功能性及分子结构可调等特点,开发了一种适合在长尺寸纤维表面分段原位合成聚苯胺层的方法,并分段涂覆导电碳材料,实现了多种分段式多功能集成纤维电极的连续化制备.通过对纤维基底进行氧化改性,可增强纤维基底对苯胺底物的亲和性,克服因毛细浸润或脱附等导致的高分子功能层边界弥散问题.在此基础上,结合新型织物结构电路设计,编织了一种可同时实现人体汗液pH值连续监测以及健康状态判断预警的织物结构集成电路模块.其可与纤维结构Zn/MnO_(2)电池共同编织,并与微型无线芯片、发光二极管等集成,实现人体健康的不间断无感无线监测及异常情况预警,展现了在未来可穿戴AI硬件中的应用潜力.The mass production of multifunctional integrated fiber electrodes is the foundation for achieving large-scale wearable applications of fiber or fabric-based electronic devices.Based on the flexible,functional and molecular structure adjustable characteristics of polymer semiconductor materials,a method for segmental in situ synthesis of polyaniline functional layers on long fiber surfaces has been put forward in this work.And then,coated with conductive carbon materials,this allows for the successful continuous preparation of segmental multifunctional integrated fiber electrodes.By modifying the fiber substrate with oxidative treatment,the affinity of the fiber substrate to the aniline substrate can be enhanced,which overcomes the problem of polymer functional layer boundary diffusion caused by capillary wetting or detachment.On this basis,according to a kind of novel textile-based circuit design,a textile-structured integrated circuit module has been developed,which can simultaneously realize continuous monitoring of human sweat pH value,health status judgment,and early warning.Co-woven with the fiber-structured Zn/MnO_(2) batteries,as well as integrated with mini wireless chips,light-emitting diodes,etc.,this integrated circuit textile enables consecutive human body wireless monitoring and timely emergency warning for abnormal situations,demonstrating its potential application in future wearable AI hardware.
