Abstract:PVDF membranes are extensively applied in ultrafiltration processes of aqueous solutions of different chemical substances owing to its outstanding properties, such as high mechanical strength, thermal stability, and chemical resistance. However, hydrophobicity of this polymer largely limits the practical application of PVDF. Therefore, it is very important to develop methods of modifying the surface of PVDF membranes with the aim to improve their properties. Polyethyleneimine, as a modifying agent, has already… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
