摘　　要：对芳纶纤维表面进行碱性镀镍,并对纤维的表面形态与性能进行测试。经过预处理的芳纶纤维,在硫酸镍30g/L,次磷酸钠25g/L,柠檬酸钠20g/L,氯化铵17g/L,温度25℃条件下进行镀镍处理。测试结果得到,镀镍后芳纶纤维的电阻率为51.2~61.9Ω·cm,纤维拉伸断裂强力为21.23cN。通过扫描电子显微镜观察,镀镍芳纶纤维表面的镀层较均匀。The aramid fiber surface nickel plating technology was investigated,and the morphology and property of fiber surface were tested.After fiber pre-treating,under the conditions of nickel salt 30g/l,sodium hypophosphite 25g/l,sodium citrate 20g/l,ammonia chloride 17g/l,and temperature 25℃,nickel plating processing was done for fiber.The results showed that the electrical resistivity of fiber was 51.2~61.9Ω·cm,the breaking strength 21.23 cN.The more uniform plating on the surface of fiber was observed using S.E.M.
