【摘要】 首次在超临界CO2与离子液体两相体系中实现了聚吡咯(PPyr)薄膜的电化学合成.与纯离子液体相比,该体系中合成的PPyr膜具有均匀平滑的表面.随着CO2压力的增加,膜的生长速度减慢,膜的表面变得更加均匀平滑.更多还原

【Abstract】 Polypyrrole(PPyr) thin film was synthesized in a supercritical carbon dioxide(scCO2)/ionic liquid biphase system with electrochemical method for the first time.The PPyr films synthesized in the scCO2 / ionic liquid biphase system have smooth and uniform surface better than that obtained from pure ionic liquid.As the pressure of carbon dioxide is increased,the film growth rate is decreased and the film surface becomes more smooth and uniform.更多还原
