摘要: 采用原位复合法制备出聚苯胺/钛酸钡复合粒子,借助TEM、XRD、FT-IR、 XPS、TG等分析手段研究了复合粒子的形貌、结构及其热性能.结果表明,复合粒子的粒径为1 μm左右,BaTiO3以40 nm左右的晶粒分散于聚苯胺基体之中,聚苯胺与钛酸钡之间存在化学键合作用,同时在一定程度上减少了纳米粒子的团聚.

Abstract: Polyaniline-barium titanate (PAn/BaTiO3) nanocomposite particles have been prepared by in situ composite technique in the presence of barium titanate nanoparticles which are synthesized by sol-gel processing.The conformation,structure and thermal properties of PAn/BaTiO3 nanocomposites particles are characterized by TEM,XRD,FT-IR ,XPS and TG.The results show that the BaTiO3 nanoparticles with diameter of about 40 nm are dispersed in polyaniline,while the diameter of the composite particles is about 1 μm.There are chemical bonds between PAn and BaTiO3 in PAn/BaTiO3 nanocomposites , at the same time,the complex can reduce the agglomeration of BaTiO3 particles to some extent.
