TQ153.14; Conductive polyacrylonitrile fibers were prepared by electroless copper plating under weak alkaline conditions, with L-ascorbic acid as reducing agent. The influences of CuSO4·5H2O, L-ascorbic acid, 2,2′-bipyridine and K4Fe(CN)6 concentration on the conductivity and mass gain percentage of the fibers were studied. The morphological structure of the fibers was characterized by scanning electron microscopy(SEM), and the mechanical properties of the fibers were analyzed through the mechanical property test. The results showed that the optimal reaction conditions were as follows: 26 g/L CuSO4·5H2O, 26 g/L L-ascorbic acid, 12 mg/L 2, 2′-bipyridine, 7 mg/L K4Fe(CN)6, and 38℃. The volume resistivity of the conductive PAN fibers prepared by the process was only 3.84×10-3 Ω·cm.
