【摘要】 合成了取代型多金属氧酸盐与HC l共掺杂聚苯胺HC l-S iW11Co/PAn材料,测试了其热稳定性、荧光性质、导电性、电化学性质及磁学性质等功能特性。实验结果表明,合成的掺杂态聚苯胺新材料HC l-S iW11Co/PAn比本征态聚苯胺(PAn)的热分解温度提高162℃;具有荧光性质和较强的导电能力,室温电导率σ=0.54 S/cm。合成的新材料体系呈顺磁性,磁化强度相对于多金属氧酸盐S iW11Co显著增强。合成的新材料为电化学活性材料。
【Abstract】 SiW11Co/Polyaniline（PAn） was synthesized by co-insertion of HCl together with substituted（heteropolyanion）.Its thermal stability,fluorescence property,conductivity,cyclic voltammetric（behavior） and magnetism were investigated.The results revealed that SiW11Co/PAn had better thermal stability.Its decomposition temperature is about 162 ℃ higher than that of PAn base.The conductivity of the material is（0.54 S/cm）.It has reversible electrochemical property.Its saturation magnetization is higher than that of the heteropolyacid,and at the same time,the system shows paramagnetism.
