Glutaraldehyde-Cross-Linked Poly(acrylic acid-co-acrylamide)/Poly(vinyl alcohol) Superabsorbent Membranes

Abstract:

The superabsorbent membranes were prepared with acrylic acid (AA) and acrylamide (AM) as the monomers, poly (vinyl alcohol) (PVA) as toughening components, potassium persulfate (KPS) as the initiator agent, and glutaraldehyde (GA) as cross-linker by means of aqueous solution polymerization. Their structures were analyzed by FTIR spectroscopy. The effects of synthesis and heat-treatment conditions on water absorbency of superabsorbent membranes were investigated. Their water absorbency with different pH was studied as well. The results showed that the superabsorbent membranes exhibited intelligently pH-responsiveness.
