Polyamide/polyaniline conductive fiber was prepared by in-situ polymerization

FTIR and microscope characterization showed that PANI had been coated on the surface of the fiber

and the conductivity of the composite fiber was tested

the single variable method was used to study the influence factors that aniline polymerized with different conditions for the conductivity of the fiber

and the effect of reaction temperature on the reaction process and the conductivity was discussed

the optimum conditions as follows: polyamide fiber was pre-treated by soaking in 30% HCOOH for 20min

aniline is 0. 8M

ammonium persulfate is 1M

doping agent is HCl (0. 8M)

polymerized in ice-water bath for 4h. Finally

the conductivity of polyamide/polyaniline conductive fiber obtained can reach to 3. 7S/m.
