摘要(Abstract)：

以涤棉纱为基材、盐酸为掺杂剂、过硫酸铵为氧化剂，采用原位聚合方法制备聚苯胺/涤棉导电纱线。通过扫描电子显微镜、VHX-5000超景深三维显微系统、傅里叶红外光谱仪、热重分析仪、X射线衍射分别对导电纱的结构和性能进行了表征。结果表明：聚苯胺原位聚合涤棉导电纱线的电阻先随着过硫酸铵浓度的增加而减小，在过硫酸铵浓度为0.4 mol/L时，导电纱的电阻达到最低值，为93.5 MΩ/cm，之后纱线电阻又随过硫酸铵浓度的增加而增加；聚苯胺处理对涤棉纱的晶型结构没有明显影响；导电纱初始分解温度低于涤棉纱，最终残炭量基本相同。
The in-situ polymerization method was used to prepare polyaniline/polyester-cotton conductive yarn with polyester-cotton yarn as the base material, hydrochloric acid as dopant and ammonium persulfate as the oxidant. The scanning electron microscope, VHX-5000 three-dimensional ultra-depth field microscopy, Fourier infrared spectroscopy, thermogravimetric analyzer, X-ray diffractometer were used to characterize the structure and properties of the conductive yarns. The results show that the resistance of conductive yarn first decreases with the increasing of ammonium persulfate concentration, when the concentration of ammonium persulfate is 0.4 mol/L, the resistance of conductive yarn reaches the lowest value of 93.5 MΩ/cm.Then the resistance of conductive yarn increases with the increase of ammonium persulfate concentration.Polyaniline treatment has no obvious effect on the crystal structure of polyester-cotton yarn. The initial decomposition temperature of conductive yarn is lower than that of polyester-cotton yarn, and the final carbon residue is basically the same.
