摘　　要：基于模板印刷技术,在针织物基底表面刮涂液态金属电路,制备液态金属导电织物,用作柔性天线。探究液态金属电路断开后导电性能的修复性,拉伸对液态金属导电织物导电性能的影响,以及液态金属电路可回收性能。结果发现:液态金属电路可以通过按压或加热修复其导电性能;液态金属导电织物具有较好的延展性,能适应一定伸长率范围内的拉伸,且不影响导电性能;可利用氢氧化钠溶液对液态金属电路进行回收再利用。最后,介绍了这种液态金属导电织物作为柔性天线在近场通信(NFC)标签(如校园卡和儿童防走失标签)中的应用。Based on template printing technology,liquid metal circuits were scraped on the substrate surface of knitted fabrics to prepare liquid metal conductive fabrics which were used as flexible antennas.The repairability of conductivity after disconnection of liquid metal circuits,influence of tension on conductivity of liquid metal conductive fabrics,and recyclability of liquid metal circuits,were studied.The results showed that,the liquid metal circuits could be repaired by pressing or heating.The fabrics had good ductility,and could adapt to a certain elongation range of tensile without affecting the conductivity.The circuits could be recycled by using sodium hydroxide solution.Finally,liquid metal conductive fabrics used as flexible antennas in near field communication(NFC)labels,such as school cards and children’s anti-lost labels were introduced.
