摘要
采用十六烷基三甲氧基硅烷(HDTMS)作为低表面能修饰剂,以氨棉混纺织物为柔性基底,通过界面氧化还原聚合反应原位负载聚吡咯(PPy)导电层,开发一种兼具高导电性与疏水功能的柔性复合织物。利用扫描电镜(SEM)和红外光谱(FTIR)表征织物的微观形貌及化学结构,测试其电学性能和接触角,并探究PPy浓度、HDTMS处理工艺对织物导电性能的调控规律。结果表明,经优化工艺制备的HDTMS/PPy/氨棉织物表现出优异的疏水性能(接触角达到121.3°)和稳定的导电性(方块电阻为140.67Ω/)。此外,该复合织物在弯曲循环测试中展现出高灵敏度与耐久性,同时具备显著的抗污性能,为多功能柔性可穿戴电子器件的设计与应用提供新思路。
Hexadecyltrimethoxysilane(HDTMS)was employed as a low-surface-energy modifier,and a spandex-cotton blended fabric served as a flexible substrate.A flexible composite fabric integrating high conductivity and hydrophobic functionality was developed through in situ interfacial redox polymerization to load a conductive polypyrrole(PPy)layer.The microstructure and chemical composition of the fabric were characterized using scanning electron microscopy(SEM)and Fourier transform infrared spectroscopy(FTIR),respectively.Electrical performance tests and contact angle measurements were conducted to evaluate the conductivity and hydrophobicity of the fabrics.The effects of the PPy concentration and HDTMS treatment processes on the conductive properties were systematically investigated.The results demonstrated that the optimized HDTMS/PPy/spandex-cotton fabric exhibited excellent hydrophobicity(contact angle of 121.3°)and stable conductivity(sheet resistance of 140.67Ω/□).Additionally,the composite fabric displayed high sensitivity and durability in bending cycle tests,along with remarkable antifouling properties.This work provides a novel strategy for designing multifunctional flexible wearable electronic devices.
