摘　　要：为了研究涤纶纤维(PET)在不同配比的石墨烯导电浆料浸渍并烘干后对其导电性能的影响,以机械法制备的1μm~3μm的石墨烯作为导电相,采用聚酯树脂作为粘结剂制备石墨烯导电浆料,随后将经过去油粗化处理的涤纶纤维浸渍在石墨烯导电浆料中浸渍一定的时间,后取出烘干从而制备出石墨烯导电纤维。采用电阻测试仪对制备出的不同导电纤维单位长度的电阻进行测试,采用单纤维强力仪测试其力学性能,采用同步热分析仪测试其热力学性能。研究表明∶该涤纶导电纤维在二次浸渍纤维能使纤维的导电性和均匀性有所提升,在加入去离子水90 g、分散剂0.75 g、聚酯树脂为WPU608以及石墨烯与聚酯树脂的比为5∶1导电性能达到最佳且为0.565Ω·cm。This paper aim to study the effect of impregnation and drying of polyester fibers(PET)in different ratios of graphene conductive slurry on their conductivity,graphene with particle size 1-3μm prepared by mechanical method was used as the conductive phase,and polyester resin was used as the binder to prepare graphene conductive slurry.Subsequently,the polyester fibers that had undergone degreasing and coarsening treatment were immersed in the graphene conductive slurry for a certain period of time,Afterwards,remove and dry to prepare graphene conductive fibers.Use a resistance tester to test the resistance per unit length of different conductive fibers prepared,use a single fiber strength tester to test their mechanical properties,and use a synchronous thermal analyzer to test their thermodynamic properties.Research has shown that the conductivity and uniformity of the polyester conductive fiber can be improved by secondary impregnation with 90 g deionized water,0.75 g dispersant,WPU608 polyester resin,and a 5∶1 ratio of graphene to polyester resin,achieving the best conductivity of 0.565Ω·cm.
