Two kinds of organic sulfonic acids, i.e., p-toluenesulfonic acid (PTSA) and sulfosalicylic acid (SSA), were used as doping acid to prepare the polyaniline-deposited functional cellulosic paper, and both the conductivity and flame retardancy of the functional cellulosic paper were investigated. The results indicated that both the conductivity and the flame retardancy of the paper composite had a close relationship with the incorporation of doping acid. Both the conductivity and the oxygen index (OI) value increased with the increase of the acid concentration. SSA performed much better than PTSA and the inorganic acids studied previously for both the conductivity and the OI value of functional cellulosic paper. The conductivity of the paper doped with SSA was more stable than that of the paper doped with PTSA, and the OI value only decreased about 1 % within 40 days for the functional cellulosic paper doped with the two doping acids. Compared with the polyaniline-deposited paper doped with PTSA, both the much higher doping level and the much smaller and more compact polyaniline particles deposition were probably responsible for the significantly better conductivity and flame retardancy of the polyaniline-deposited paper doped with SSA.
