POLYMERIC FILM MADE FROM CAGE TYPE POLYHEDRAL OLIGOMERIC SILSESQUIOXANE (POSS) AND HYDROPHILIC COMONOMER

摘要

PROBLEM TO BE SOLVED: To provide a polymeric film made from cage type polyhedral oligomeric silsesquioxane (POSS) and a hydrophilic comonomer.;SOLUTION: A composite membrane includes a filtration membrane and a layer on the surface of the filtration membrane. The layer includes a polymer including a cage type polyhedral oligomeric silsesquioxane (POSS) derivative having a hydrophilic moiety bonded to at least one vertex thereof. A method for making the composite membrane includes a step of applying a photopolymerizable composition including a POSS compound, the hydrophilic comonomer and a photoinitiator to the surface of the filtration membrane. The composition is cured to form a hydrophilic layer on the filtration membrane.;COPYRIGHT: (C)2011,JPO&INPIT
