The present invention provides a charge transport film which is prepared through subjecting a coating film including at least one charge transporting agent to an atmospheric pressure plasma treatment, wherein electron transfer between the charge transport film and a substance that contacts with the charge transport film is promoted, and deterioration in performance due to diffusion and mixing or crystallization of low molecular weight components, such as a charge transporting agent, incorporated in a cured film is suppressed also in the case of film formation by a wet method, and which exhibits excellent charge transportability and stability over time; a production method with good productivity; and a light-emitting element and photoelectric conversion element equipped with the charge transport film, the atmospheric pressure plasma treatment being preferably a treatment that applies plasma, which is generated using a plasma generating apparatus and conveyed using an inert gas, to the coating film.
本发明提供了一种充电传输膜,该膜是通过将至少包括一种充电传输剂的涂层膜暴露于大气压等离子体处理下制备的。在该膜与接触其的物质之间促进电子转移,同时抑制低分子量组分(例如充电传输剂)在固化膜中扩散、混合或结晶所导致的性能退化,即使是通过湿法形成膜的情况下也是如此。该膜表现出优异的电荷传输性和稳定性。本发明还提供了一种生产方法,具有良好的生产效率;以及配备该充电传输膜的发光元件和光电转换元件,其中大气压等离子体处理优选地是将使用等离子体产生装置生成的等离子体用惰性气体传送到涂层膜上的处理。
