%X 以高强度的聚酰亚胺（PI）纤维为基纤，采用表面改性离子交换和化学镀相结合的方法，成功制备了高强度、高导电性和热稳定性好的聚酰亚胺-Ni （PI-Ni）复合导电纤维，采用SEM观察纤维的微观形貌，通过XRD和EDS表征了镀层组成及相态结构，测试了纤维的力学性能、导电性、界面黏结性能及热性能。结果表明，PI-Ni纤维表面平整光滑，完整致密，镀层为非晶态Ni-P合金。PI-Ni束丝拉伸强度约为1.2 GPa，电阻率为1.76×10-4 Ω·cm，5%热失重温度为611℃，耐热性能优异，是一种高性能的有机导电纤维。 Surface-nickeled polyimide (PI-Ni) fibers with high tensile strength, high conductivity and high-temperature stability were successfully prepared by using high-strength PI fiber as the matrix via a surface-modification ion-exchange and electroless nickel plating method. The prepared PI-Ni fibers were characterized by SEM, XRD, EDS, mechanical test, electrical conductivity measurement, adhesion test and TGA, respectively. The results indicate that the coated metal layer on the PI-Ni fibers is amorphous Ni-P alloy, which has smooth, detect-free and compact surface morphologies. The PI-Ni fiber is prepared with the tensile strength up to 1.2 GPa, surface resistivity of 1.76×10-4 Ω·cm, and 5%-weight-loss temperature of 611℃, which is a high-performance organic conductive fiber. 国家重点基础研究发展973计划（2014CB643604）；江苏省杰出青年基金（BK20140006）
