| Research Abstract |
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.
