摘要
以聚对苯二甲酰对苯二胺(简称芳纶,PPTA)纤维为基材,使用环氧氯丙烷(ECP)对PPTA表面进行有机修饰,得到了ECP改性的PPTA纤维(ECP-PPTA),然后使苯胺单体在ECPPPTA表面接枝聚合,制备了ECP-PPTA/PANI复合导电纤维。用傅里叶变换红外分光光度计(FT-IR)、扫描电子显微镜(SEM)、热重分析仪(TGA)及X射线衍射分析仪(XRD)等分析测试方法对ECP-PPTA及ECP-PPTA/PANI复合导电纤维进行了表征。结果表明:PPTA经ECP改性后,PANI成功接枝在PPTA表面,制备的ECP-PPTA/PANI复合导电纤维的电阻率低于PPTA/PANI纤维的,其室温电阻率最低为0.32MΩ·m。
Composite conductive fibers ECP-PPTA/PANI were prepared by the encapsulation of poly-pphenyleneterephthamide（PPTA）template with polyaniline（PANI）after the surface modification with epichlorohydrin（ECP）on the surface of PPTA fibers.Moreover,the modified fibers（ECP-PPTA）and ECP-PPTA/PANI were studied by Fourier Transform Infrared Spectroscopy（FT-IR）,Scanning Electron Microscopy（SEM）and X-Ray Diffraction（XRD）.The thermal stability was studied by the Thermo Gravimetric Analyzer（TGA）.Results showed that PANI was grafted on the surface of PPTA successfully,and the resistivity of ECP-PPTA/PANI were better than PPTA/PANI composite conductive fibers,and the lowest room temperature resistivity of ECP-PPTA/PANI was about 0.32 MΩ·m.
