제목 synthesisof sulfonted polyphenylsilsesquioxane and polyhedral phenyl silsesquioxnae, andstudy of ion conductivity
초록 To apply the drect methanol fuel cell membrane (DMFC), a simple prepared Polyphenylsilsesquioxane and polyhedralphenyl silsesquioxane were sulfonated by chlorosulfonic acid. sulfonation was crried out as follow 30 , 60, 120, 480 and 1440 min and also confirmed sulfonate yield. And then sulfonated-PPSQ blended with PVA(poly vinyl alcohol) and cast film. Prepared film was characterized by ion conductivity, WAX, AFM, SEM, XPS etc.. ion conductivity showed about 5x10-4 s/cm and WAX and SEM showed well mixed film condition.
