盐酸掺杂的聚苯胺（PANI.HCl）纳米颗粒和聚（氯乙烯）（PVC）的共混物是通过使用超声波将沉淀的聚苯胺胶体颗粒再分散在PVC的四氢呋喃溶液中并从分散体流延成膜来制备的。该共混物在PANI体积分数为4.02 X 10(-4)时具有极低的渗滤阈值。讨论了直接浇铸在 TEM 网格上的共混物薄膜的透射电子显微镜 (TEM) 显示的共混物形态。高于渗透阈值时分散的 PANI 。 HCl 相显示出球状网络形态，与之前观察到的 PANI 纤维状网络形态相反。通过本方法制备的HCl-聚(乙烯醇)共混物。
Blends of hydrochloric acid-doped polyaniline (PANI . HCl) nanoparticles and poly( vinyl chloride) (PVC) have been prepared by redispersing sedimented colloidal particles of PANI in tetrahydrofuran solutions of PVC using ultrasound and casting the film from the dispersion. The blends have the characteristics of extremely low percolation threshold at a volume fraction of PANI of 4.02 X 10(-4). The morphology of the blends as revealed by transmission electron microscopy (TEM) of the blend films directly cast on TEM grids is discussed. Above the percolation threshold the dispersed PANI . HCl phase shows a globular network morphology in contrast to the fibrillar network morphology observed earlier for PANI . HCl-poly(vinyl alcohol) blends prepared by the present method.
