摘要
采用金刚石压贴超高压装置对聚苯胺进行超高压处理，并在超高压下进行聚苯胺的电阻和红外光谱的就位测定。发现聚苯胺的电阻随压力的增加而减小，但压力超过３．６ＧＰａ后又急剧增大。ＦＴ－ＩＲ测定的结果表明。
Polyaniline was handled under ultrahigh pressure generated by a diamond anvil cell. An in situ measurement of the conductivity and FT IR spectroscopy of polyaniline was done under ultrahigh pressure. It was found that the resistance decreased as the pressure increased, but the resistance increased drastically when the pressure exceeded 3.6GPa. The FT IR results indicated that the ultrahigh pressure would result in an irreversible structural change of the quinone units in polyaniline molecular chains.
