Abstract: |
Cotton fiber is the most common fiber, which has highly absorption to chemicals, low price and high strength. Polyaniline(PANI) is a intrinsic conductive polymer with the altogether clutche electronic structure, stable electrochemical nature, unique doping mechanism, excellent conductive properties after doping and simple preparation process, so it is the most likely to be widely used. PANI conductive polymer has become a hot spot in the conductive polymer area. In this study, a conductive composite fiber was prepared. The base material was cotton fiber, the solvents or doping acids of the reaction were several different acids, the oxidation reagent was ammonium persulfate, and the method was “in situ polymerization”, then the polyaniline/cotton(PANI/C) composite materials were prepared, the conductivity of products which had been prepared under different conditions were studied, which main be the affection of reaction conditions to the conductivity of PANI/C fiber, including the acid type of doping, soaking time, reaction time, reaction temperature and the amount of antioxidant. By the means of analysing cost and reaction efficiency comprehensively, the final conclusion was got: oxidating with ammonium persulfate(1.2g), doping with Dodecylbenzenesulfonic acid, soaking 2 hours, reacting on 0℃, reacting 4 hours.
