摘　　要：针对目前传统涂覆方法中导电涂层易脱落的问题,提出溶解涂覆方法制备涂覆型导电纤维。将聚苯胺(PANI)分散在甲酸水溶液中配置成涂覆液,经特殊设计的设备将涂覆液均匀地涂覆在聚己内酰胺(PA6)纤维表面,经超声波水洗后制备成涂覆型PANI/PA6导电纤维并将所得PANI/PA6纤维在小样织机上按20 mm间距纬向织入基础织物中。通过FT-IR、DSC、TG分析,水洗和温度处理等实验对PANI/PA6纤维的结构与性能进行研究。结果表明:在水洗和热处理后,PANI涂层不易脱落,溶解涂覆型PANI/PA6纤维具有较好的导电耐久性;有机酸掺杂所得PANI/PA6纤维的体积比电阻较低,且具有较好的热稳定性。Owing to the fact that the electroconductive coating by traditional coating method tends to drop,this study proposed a dissolving-coating method for preparation of coated electroconductive fibers,in which the coating liquid was prepared by dispersing polyaniline（PANI） in the formic acid aqueous solution and then evenly applied on the surface of polycaprolactam（PA6） fibers with specially designed equipment.After ultrasonic washing,PANI /PA6 fibers were obtained and woven weftwise into the substrate fabric at a space of 20 mm on a laboratory weaving machine.FT-IR,DSC,TG,water washing and heat treatment were employed to investigate the structure and properties of the PANI /PA6 fibers.The results showed that PANI coating is difficult to peel off after the heating and washing treatment.In addition,PANI /PA6 fibers doped by organic acid illustrate good electrical property and thermal stability.
