摘要
以FeC l3为氧化剂,采用原位化学聚合的方法制备了聚噻吩/SBA-15新型复合材料,并对其结构和性能进行了表征。结果表明,小角X射线衍射和氮气吸附与脱附说明复合材料具有规则的介孔结构并且孔径明显小于分子筛SBA-15的孔径,红外光谱分析进一步证明PT进入了SBA-15的介孔孔道内,热重分析表明,聚噻吩进入孔道之后热稳定性得到了提高。
A new composite,polythiophene(PT) confined in mesoporous silica(SBA-15) was synthesized.PT was formed in the pores of SBA-15 by subsequent oxidative polymerization with FeCl3.Different techniques were employed to characterize the resulting composite.SAXRD and N2 adsorption/desorption analysis showed that the composite possessed typical mesoporous structure,and the residual pore volume of composite was significantly lower than that of pure empty SBA-15.FTIR spectra confirmed the presence of polythiophene inside pore channels of the host and TG proved confinement effect in the channel system.
