摘要:
Compositions are disclosed comprising electrically conducting polyaniline and particular substituted compounds that simultaneously form hydrogen bonds and ring-ring interactions with, respectively, the NH-groups and the six-membered rings of the conducting polyanilines. The present conducting polyaniline compositions show drastically enhanced processibility and their blends with insulating or semiconducting materials exhibit significantly improved electrical properties.
摘要:
An easily processable conductive polymer material based on a polyaniline or a derivative thereof and a protonic doping acid is prepared in the invention:
(a) by producing a mixture which comprises 1-20 wt.% polyaniline or its derivative, 50-90 wt.% protonic doping acid, calculated as dodecylbenzene acid, and 1-45 wt.% a component which is water and/or C₁-C₃ alcohol, (b) by feeding the mixture obtained from step (a) into a mixing apparatus, in which it is mixed by shear forces at a temperature of 50-400 °C, and (c) by recovering the blend obtained from step (b) from the melt-mixing apparatus, and (d) by carrying any further treatment of the blend recovered in step (c).
