제목 Superhydrophobic PVDF-based Cellulose Membranes Prepared via Surface-Grafting Polymerization
초록 A PVDF-grafted cellulose membrane (PVDF-g-CM) is prepared as a superhydrophobic membrane for oil/water separation. Surface-initiated grafting polymerization of PVDF was carried out via RAFT/MADIX of PVDF on a RAFT CTA-attached cellulose membrane. PVDF is a hydrophobic fluoropolymer, with low surface energy from the two C-F bonds. Due to the widely known chemical and thermal stability of PVDF, PVDF is a promising candidate as a grafting material for oil/water separation. The superhydrophobic PVDF-g-CM showed a WCA of ~150° and used as a separation membrane for oil/water mixtures. PVDF-g-CM showed high separation efficiencies after multiple cycles and also showed physical, chemical, and thermal stability, compared to the PVDF-coated CM.
