摘　　要：合成了对甲基苯磺酸(p-TSA)掺杂的导电聚苯胺(PANI)及聚苯胺/氧化钇(PANI/Y2O3)复合材料。比较了不同实验条件对两种材料电导率的影响,研究了两种材料的热稳定性及粒径分布。结果表明,在所研究实验条件下,PANI/Y2O3的电导率低于PANI,而热稳定性则优于PANI;Y2O3的掺入使PANI的粒径减小。In this paper,two electro-conducting materials polyaniline （PANI） and composite polyaniline/yttria（PANI/Y2O3） doped by 4-methylbenzenesulfonic acid were synthesized. Influences of experimental conditions on their conductivities were compared, and their thermal stabilities and particle diameter distributions were studied either. The results showed that the electrical conductivity of PANI/Y2O3 was lower than that of PANI, but its thermostability was higher. The particle diameter of PANI/Y2O3 was smaller than that of PANI.
