Polyaniline-deposited paper composites doped with three inorganic acids were prepared via in situ polymerization, and their flame-retardant properties were investigated. Both the conductivity and flame retardancy of the composite increased with the increase of the amount of the polyaniline deposited. The doping acid played a very key role in both the conductivity and flame retardancy of the composite. The comprehensive properties of the composite could be improved when codoped with an equimolar mixture of H(3)PO(4) and H(2)SO(4) or H(3)PO(4) and HCl. The decay of the flame retardancy of the composite in atmosphere was due to the dedoping of the polyaniline deposited on cellulose fibers.
通过原位聚合制备了掺杂三种无机酸的聚苯胺沉积纸复合材料，并研究了它们的阻燃性能。复合材料的电导率和阻燃性能均随沉积聚苯胺量的增加而提高。掺杂酸在复合材料的电导率和阻燃性能中都起着非常关键的作用。当用等摩尔混合的 H3PO4和 H2SO4或 H3PO4和 HCl 共掺杂时，复合材料的综合性能可以得到提高。复合材料在大气中的阻燃性能下降是由于沉积在纤维素纤维上的聚苯胺脱掺杂所致。
