Polymeric films made from polyhedral oligomeric silsesquioxane (POSS) and a hydrophilic comonomer

摘要

A composite membrane includes a filtration membrane and a layer on a surface of the filtration membrane. The layer includes a polymer including a polyhedral oligomeric silsesquioxane (POSS) derivative with a hydrophilic moiety attached to at least one vertex thereof. A method for making a composite membrane includes applying to a surface of a filtration membrane a photopolymerizable composition including a POSS compound, a hydrophilic comonomer, and a photoinitiator. The composition is cured to form a hydrophilic layer on the filtration membrane.
