In this communication, a new in-vacuum electropolymerization process combined with vapor-phase deposition using ionic liquid (IL) is proposed, in which source molecules are sequentially introduced into an IL layer coated on a patterned electrode substrate under the control of applied electrode potential. Based on this process concept, the direct polymerization of terthiophene into polythiophene films in IL was successfully demonstrated. The process can be numerically simulated to reproduce well the dynamic time-response of the oxidative current to the vapor deposition sequence and to prove its capability to precisely control electropolymerization by the saturated oxidative current density proportional to the vapor deposition rate.

在离子液体中将气相沉积的源分子在真空中进行电聚合成聚合物膜

在这种交流中，提出了一种新的真空电聚合工艺，该工艺与使用离子液体（IL）进行气相沉积相结合，在该工艺中，在施加的电极电势的控制下，将源分子顺序引入到涂覆在有图案的电极基板上的IL层中。基于该工艺概念，成功地证明了在IL中将噻吩直接聚合成聚噻吩薄膜。可以对该过程进行数值模拟，以很好地再现氧化电流对气相沉积序列的动态时间响应，并证明其能够通过与气相沉积速率成比例的饱和氧化电流密度来精确控制电聚合的能力。
