| 摘 要： | 以Keggin结构铝取代杂多硅钨酸盐异构体α·β_i-K_5 SiW_(11)Al(H_2O)O_(39)]·xH_2O(β_i=β_1,β_2,β_3)为掺杂剂制备了α·β_i-SiW_(11)Al/PANI电子聚合物材料.用红外光谱、紫外光谱、X-射线粉末衍射、SEM、热重分析等对此材料进行了表征,测定了材料的导电性和荧光性,研究了它们的热稳定性.结果表明:掺杂了铝杂多硅钨酸盐异构体的聚苯胺都具有较好的热稳定性,比本征态聚苯胺的分解温度提高了121.9℃,材料最好的电导率为0.83S·cm~(-1).荧光光谱表明,掺杂材料具有相似的荧光性质,对应的荧光发射波长为420和484nm,发蓝绿光.

| Abstract: | α·β_i-SiW_(11)M/PANI electron polymer materials were prepared by using Keggin structure aluminum-sub-stituted heteropolysilicotungstate isomersα,β_i-K_5 SiW_(11) Al(H_2O_2) O_(39)]·xH_2O (β_i=β_1,β_2,β_3) as depart. The materials were characterized by elemental analysis, IR,TG, UV-Vis, SEM and XRD spectra techniques. The conductivity and fluores-cence property were determined, and thermal stability was studied. Results showed that the best conductivity of the mate-rials was 0.83S·cm~(-1) , and they had better thermal stability and decomposition temperatures which were about 121.9℃ higher than that of emeraldine. The results showed that the materials possessed fluorescence property and λ_(em) = 420 and 484nm, and they emitted blue light,in fluoresecce spectrum. |
