Surface cross-linked hydrogel for forward osmosis

Surface cross-linked hydrogel for forward osmosis

To understand the feasibility of using surface-crosslinked semi-Interpenetrating Network (semi-IPN) hydrogel in powder form (<200 µm) containing Poly N-isopropylacrylamide (PNIPAM) matrix and linear Poly Sodium Acrylate (PSA) as a suitable draw solute. Post-synthesis surface crosslinking was cond...
