纳米金属Pt催化苯胺无电聚合的方法研究

Study on the Method of Electroless Polymerization of Aniline Catalyzed by Platinum Nanoparticles

在酸性条件下,采用纳米金属Pt催化合成聚苯胺,以透射电子显微镜(TEM)、傅立叶红外光谱(FT IR)对产物的晶貌、分散状态和谱学性质进行表征.系统地研究了质子酸介质,苯胺浓度等因素对苯胺聚合速度及其性质的影响,并简要讨论了其影响因素.

In acid solution, polyaniline (PAN) was polymerized using Pt nanoparticles as catalyst for the first time. The crystal image, distribution and the spectroscopy character of obtained products were characterized by TEM (Transmission electron microscopy) and FT-IR (Fourier transform infrared spectroscopy). The polymerization rate and the properities of PAN synthesized in different acid solution with different density of aniline have been studied systematically, and the possible effect and polymerization mechanism has also been discussed briefly.
