本研究的目的是制备和表征等离子体聚合阴离子交换膜。在这项研究中，等离子体聚合与4-乙烯基吡啶和六氟丙烯，然后季铵化使用1-溴丙烷进行制备阴离子交换层到聚烯烃基多孔基板。考察了聚合时间、基材厚度、孔径以及热压处理对聚合物孔结构的影响。通过XPS和FT-IR分析，确定了产物的化学组成和季铵化反应。衬底越薄，电导率越高。qPM 9 -15显示电导率为44.9 mS/cm。qPM 22 -5的最大功率密度（MPD）（32.6 mW/cm 2）上级qPM 20 -5（19.2 mW/cm 2），这是由于高电导率。进行热压处理。qPM 18 - 30 H的吸水率（17.2%）、电导率（78.7 mS/cm）和t-（0.93）。通过使用qPM 18 - 30 H存档OCV（0.89 V）、MPD（32.4 mW/cm 2）。

The objectives of this study are to prepare and characterize the plasma polymerized anion exchange membranes. In this study, plasma-polymerization with 4-vinylpyridine and hexafluoropropylene followed by quaternization using 1-bromopropane was conducted to fabricate anion exchange layer onto polyolefin based porous substrates. The effect of polymerizationtime, the thickness and porous size of the substrates and hot-press treatment was estimated. From the results of XPS and FT-IR, the chemical composition and quaternization was confirmed. The thinner the substrates were, the higher the conductivity became. qPM9-15 showed the conductivity of 44.9 mS/cm. The maximum power density (MPD) of qPM22-5 (32.6 mW/cm2) was superior to that of qPM20-5 (19.2 mW/cm2) due to the high conductivity. Hot-press treatment was conducted. qPM18-30H had the water uptake (17.2 %), conductivity (78.7 mS/cm) and t- (0.93). The OCV (0.89 V), MPD (32.4 mW/cm2) was archived by using qPM18-30H.
