Conductive Paper Manufactured with the Composite of PAn/Pulp Fiber(I)——Effects of Adsorption and Polymerization Conditions on the Performances of Conductive Paper

In this paper,aniline was polymerized into the micro-pore wall of the pulp fiber by in-situ adsorption polymerization process in order to manufacture conductive paper.The effects of different reaction conditions including amount of oxidant(potassium persulfate or ammonium persulfate),reaction temperature and reaction time on the surface resistance of conductive paper were studied in detail.The optimum adsorption polymerization conditions were: polymerization time 105 minutes,reaction temperature 5°C.The mass ratio of oxidant to aniline is dependent on the types of oxidant.When potassium persulfate was used as oxidant,the optimum mass ratio of oxidant to aniline was 1∶2 and the surface resistivity of the conductive paper was 481 Ω/cm~2.However,the optimum mass ratio of oxidant to aniline was 3∶4 and the surface resistivity was up to 108 Ω/cm~2 when ammonium persulfate was used as oxidant.Thus,ammonium persulfate is better than potassium persulfate as oxidant.
