An anchor for help: a cross-linking moiety for block copolymer membrane stabilization for ultrafiltration applications in water

Block copolymer membranes are an exciting class of materials used to separate small contaminants from water. Covalent cross-linking of the membrane matrix is one approach to alleviate stability issues, which limit their application nowadays. In the current work, membranes from amphiphilic block copo...

Description
Summary:Block copolymer membranes are an exciting class of materials used to separate small contaminants from water. Covalent cross-linking of the membrane matrix is one approach to alleviate stability issues, which limit their application nowadays. In the current work, membranes from amphiphilic block copolymers are manufactured and cross-linked using a UV-active radical initiator moiety. In this work, the authors show the increased compacting resistance of a SNIPS membrane featuring cross-linkable, allylic double bonds in the membrane matrix.
