摘　　要：通过原位聚合法工艺,利用聚吡咯和还原氧化石墨烯对蚕丝织物进行导电整理,制得蚕丝导电心肌补片,并探讨其优化整理工艺。测试结果表明:导电心肌补片表面的导电颗粒随吡咯单体和氧化石墨烯质量浓度上升而增多,其电导率也随之提高;表面电阻随着吡咯单体浓度增加而降低,原位聚合的吡咯单体最佳质量浓度为1 g/L,氧化石墨烯最佳质量浓度为8 g/L;聚吡咯和还原氧化石墨烯可以很好地聚合在蚕丝织物表面;随着原位聚合质量浓度的增加,导电心肌补片的热学性能、降解率有所提高,杨氏模量呈下降趋势。综合分析认为:利用原位聚合法制备蚕丝导电心肌补片具有很好的可行性。A new type of silk conductive cardiac patch is prepared by in-situ polymerization using polypyrrole and reduced graphene oxide to conduct conductive finishing on silk fabrics,and the optimization of its finishing process is discussed.The test results show that the scanning electron microscope images show that the conductive particles on the surface of the conductive cardiac patch increase with the increase in the concentration of pyrrole monomer and graphene oxide,and their electrical conductivity also increases.Its surface resistance decreases as the concentration of pyrrole monomer increases.The optimal concentration of pyrrole monomer for in-situ polymerization is 1 g/L,and the optimal concentration of graphene oxide is 8 g/L;The infrared test results show that polypyrrole and reduced graphene oxide are polymerized well on the surface of silk fabrics;With the increase of the concentration of in situ polymerization,the thermal properties and degradation rate of conductive cardiac patch have improved,and their Young’s modulus indicators show a downward trend.Comprehensive analysis shows that the preparation of silk conductive cardiac patch by in situ polymerization is very feasible.
