摘要/Abstract

摘要： 采用化学氧化法在不同温度下制备聚噻吩和聚3辛基噻吩，通过红外光谱（FTIR）, X衍射分析（XRD），核磁共振谱图（NMR），X光电子能谱（XPS）和紫外可见光谱（UVVis）等手段对聚合物进行了研究.结果表明，聚噻吩侧链基团和制备温度会影响聚合物的构型结构，引起聚合物结晶度的变化.聚3-辛基噻吩结晶度最低，低温制备的聚噻吩结晶度最高.导电性能研究表明，聚噻吩的构型结构和结晶度直接影响其电导率.

Abstract: Polythiophene and Poly(3octylthiophene) were synthesized by direct oxidative polymerization under different temperatures. The chemical structure of samples were characterized by FTIR, XRD, NMR,XPS and UVVis respectively. The results showed that the strcture and the degree of crystallinity(DC) of samples depended on the length of side chain and reaction temperature. Poly(3octylthiophene) has a lower DC.Polythiophene prepared under low temperature has a higher DC. Experimental results suggested that there is certain relationship between DC, chemical structure and conductivity of samples.
