Study on spontaneously-formed transparent conducting organic/inorganic nanocomposite materials

点击翻译按钮获取中文摘要

When vacuum evaporated metals were contacted on a green-colored electropolymerized polycarbazole film, decoloration reaction (hybridization reaction) occurred to give novel transparent conducting polymer films. The mechanistic and chemical analyses revealed that the hybridization reaction was the combination of corrosion reaction and dedoping reaction. If we use Ga metal and its arroys, the hybridization reaction was found to proceed at room temperatures simply by their contact with the polycarbazole film. Additionally, use of soluble polycaribazoles made possible the hybridization reaction in the solution phase to produce transparent conducting inks.
