PH-responsive PVDF Composite Membranes Blended with Amphiphilic Poly (methacrylic acid)-block-polydimethylsiloxane-poly (methacrylic acid)

In this work, a well-defined amphiphilic triblock copolymer poly (methacrylic acid)-block-polydimethylsiloxane-poly (methacrylic acid) (PMAA-b-PDMS-b-PMAA) synthesized via atom transfer radical polymerization was employed for the preparation of pH-responsive poly (vinylidene fluoride) (PVDF) membrane by facile blending method. The resultant blend membrane showed significantly pH-responsive characteristics as confirmed by filtration experiments.
