【 摘 要 】

The in-situ polymerization method was used to prepare poly (3,4-ethylene-dioxythiophene dioxide thiophene)-polystyrene sulfonate/polyacrylonitrile (PEDOT-PSS/PAN) composite conductive fiber. The results indicate that more PEDOT particles grow on the surface of in-situ PEDOT-PSS/PAN composite fibers than PAN fiber, which has the conductivity of 9.83 S/cm nearly twice of that of the composite fiber before in-situ polymerization. The crystallinity of the in-situ PEDOT-PSS/PAN composite fiber is a little lower than that of the fiber before in-situ polymerization, but the thermal stability goes by contraries. Furthermore, the in-situ polymerization process has minor effects on the mechanical properties of the fibers. The breaking strengths, elongation at break and initial modulus of the in-situ PEDOT-PSS/PAN composite fiber are 0.67 CN/dtex, 33.90% and 4.63 CN/dtex respectively, which can be waved. It is estimated that this in-situ PEDOT-PSS/PAN composite conductive fiber will have the electromagnetic wave absorption function, which can be used in military as wave absorption material.
