Preparation, characterization and properties of PVDF-g-PAMPS/PMMA-co-PAMPS/silica nanoparticle as a new proton exchange nanocomposite membrane

What is it about?

In this study, preparation and characterization of PVDF/PMMA-co-PAMPS/silica nanocomposite membranes as a new proton exchange membrane were investigated. Polyvinylidene fluoride (PVDF) containing pendant sulfonic acid groups was synthesized by grafting through RAFT polymerization of 2-acrylamido-2-methyl-propanesulfonic acid (AMPS) from vinyl pendent groups of already modified PVDF as a macro-monomer. The synthesized PVDF graft copolymer (PVDF-g-PAMPS) was blended with miscible copolymer containing sulfonated segments (PMMA-co-PAMPS) and sulfonic acid functionalized silica nanoparticles in order to achieve high performance nanocomposite proton exchange membrane.
