摘要:
采用纳米金属Pt催化合成聚苯胺 ,以透射电子显微镜 (TEM )和傅里叶红外光谱 (FT -IR)对产物的晶貌、分散状态和谱学性质进行表征。比较了纳米Pt颗粒与Pt片对苯胺聚合速度的影响 ,并对影响因素及聚合机理进行了简要讨论。结果表明 :用纳米金属Pt催化苯胺无电聚合可以大大缩短反应时间 ,在相同的条件下反应 2~ 3h就能在酸性介质中得到掺杂性的聚苯胺 ;用此方法合成聚苯胺 ,其FT -IR谱图与该征态的聚苯胺相比吸收峰产生“蓝移”现象。
Abstract:
Pt nanoparticles as catalyst were used to polymerize polyaniline. The crystal imag e, the dist ributable property and the spectroscopy character of the obtained products were characterized by T EM ( t ransmission elect ron microscopy ) and FT - IR ( Fourier t ransform inf rare spect roscopy) . T he ef fect of Pt nanopart icles on the polymerization rate w as compared w ith that of Pt plate, and the possible element s and polymerizat ion mechanism were also brief ly discussed. Results show that: using Pt nanopart icles as electroless polymerizat ion catalyst can greatly shorten the react ion time, the acid-doped PAN can be fabricated w ithin 2~ 3 hours in the same condition and the FT- IR spectrum of PAN synthesized by this method has the characterist ics of ” blue-shift“.
