【摘要】 采用对甲苯磺酸(PTSA)和磺基水杨酸(SSA)两种有机磺酸作掺杂剂原位合成制备了聚苯胺沉积型导电和阻燃双功能纸。研究结果表明,纸的导电和阻燃性能均与掺杂酸的并入有密切关系。纸的电导率与氧指数(OI)值均随掺杂酸浓度的增加而增加,SSA掺杂纸样的导电和阻燃性能均优于PTSA掺杂纸样以及以前所研究的无机酸掺杂纸样。SSA掺杂纸样的导电稳定性明显好于PTSA掺杂纸样,而两种有机磺酸掺杂的纸样的OI值40天内均仅下降了1%左右。与PTSA掺杂纸样相比,SSA掺杂纸样较高的掺杂水平对其优异的导电和阻燃性能负责。更多还原

【Abstract】 Two kinds of organic sulfonic acids,i.e.,/7-toluenesulfonic acid(PTSA) and sulfosalicylic acid(SSA),were used as doping acid to prepare the polyniline-deposited bifunctional paper with conductivity and flame retardancy.The results indicated that both the conductivity and the flame retardancy of the paper had a close relationship with the incorporation of doping acid.Both the conductivity and the oxygen index(01) value increased with the increase of the doping acid concentration.SSA performed better than PTSA and the inorganic acids studied previously for bom the conductivity and the 01 value of bifunctional paper.The conductivity of the paper doped with SSA was more stable than mat of the paper doped with PTSA,and the 01 value only decreased about 1%within 40 days for the bifunctional paper doped with the two doping acids.Compared with the polyaniline-deposited paper doped with PTSA,the higher doping level was responsible for the better conductivity and flame retandency of the polyaniline-deposited paper doped with SSA.更多还原
