A graphene oxide modified cellulose nanocrystal/PNIPAAm IPN hydrogel for the adsorption of Congo red and methylene blue

Abstract

A simple strategy is developed to fabricate a graphene oxide modified cellulose nanocrystal/PNIPAAm IPN (GO-CNC/PNIPAAm IPN) hydrogel. It is a high-efficiency and low-cost adsorbent for the removal the anionic dye CR and cationic dye MB.
