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

摘要

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.
