Preparation of polymer-carbon nanotubes composite hydrogel and its application as forward osmosis draw agent

In this study, we functionalized multiwall carbon nanotube with polar groups including COOH and OH groups (F.MWCNT) and synthesized composite polymer hydrogel via dispersion in monomer solution and by using a simple poly (acrylic acid-co-maleic anhydride) (PAA-co-PMA) crosslinking reaction. Incorporation of the F.MWCNT phase into the PAA-co-PMA hydrogel network was verified using Fourier transformation infrared spectroscopy (FTIR) and scanning...
