The membrane of cobalt electropolyurushiol coordination polymer was obtained by the reaction of cobalt chloride isopropyl alcohol solution with electropolyurushiol.The membrane of coordination polymer was characterized by FT-IR
XPS
DTA-TG
DMTA and AES
and its composition and structure were determined.Each Co2+ ion was coordinated with hydroxyls of two units in the EPU molecule
and cross-link was formed further because of producing σ coordination bond
thus hydrophobic membrane of coordination polymer was formed.Therefore its glass transition temperature increased and heat resistance was enhanced considerably.It was found that the coordination polymer membrane activated by Na2SO3 can catalyze polymerization of VAc in water phase in room temperature.
