摘要
为解决传统蚕丝织物因绝缘性限制了其在高端领域应用的问题,通过构建氧化石墨烯(GO)/聚苯胺(PANI)复合体系对蚕丝织物进行导电改性,赋予织物持久的导电性能。采用超声改良化学法制备GO悬浮液,通过乳化-超声法制备PANI微乳液并优化其制备参数,再制备GO/PANI复合乳液,浸渍整理蚕丝织物并烘干。利用数字万用表测量织物表面电阻、扫描电子显微镜观察织物表面形貌,分析织物导电性能。结果表明:PANI微乳液的最佳制备参数为吐温80质量浓度20 g/L、超声时间3.5 h、苯胺浓度0.5 mol/L;GO/PANI蚕丝织物导电性能优于PANI蚕丝织物,且当PANI浓度为3.0 mol/L、GO质量浓度为60 g/L时,GO/PANI蚕丝织物的导电性能最佳,此时织物表面形成了连续的三维导电网络结构,纤维间空隙被有效填补。研究结果可为制备蚕丝导电织物,拓宽其在医疗、生物及工业等领域的应用提供参考。
To address the issue of traditional silk fabrics being restricted in high-end applications due to their insulating property,a conductive modification of silk fabrics was carried out by constructing a graphene oxide(GO)/polyaniline(PANI)composite system,thereby endowing the fabrics with durable conductive performance.The GO suspension liquid was prepared using an improved ultrasonic-assisted chemical method,while the PANI microemulsion was prepared via an emulsification-ultrasonic method,with its preparation parameters optimized.Subsequently,the GO/PANI composite emulsion was prepared,and the silk fabrics were finished through dipping and dried.The surface resistance of the fabrics was measured using a digital multimeter,the surface morphology of the fabrics was observed using a scanning electron microscope,and their properties were analyzed.The results showed that the optimal preparation parameters for the PANI microemulsion were Tween 80 mass concentration of 20 g/L,ultrasonic time of 3.5 h,and aniline concentration of 0.5 mol/L.The conductive performance of GO/PANI finished silk fabrics was superior to that of PANI finished silk fabrics.Moreover,when the PANI concentration was 3.0 mol/L and the GO mass concentration was 60 g/L,the conductive performance of the GO/PANI finished silk fabrics was optimal,at which point a continuous three-dimensional conductive network structure was formed on the fabric surface,effectively filling the gaps between fibers.The research findings can provide references for the preparation of conductive silk fabrics and the expansion of their applications in fields such as healthcare,biology,and industry.
