Reduced graphene oxide decorated superporous polyacrylamide based interpenetrating network hydrogel as dye adsorbent

Herein, nano-CaCO3 is utilized as exfoliating pore forming agent to enhance the structural porosity of reduced graphene oxide based hybrid polyacrylamide (PAAm) hydrogel for the application of dye removal. The structural incorporation of microcrystalline chains (MCC) to the hydrogel structure is adopted to form stable interpenetrating polymer network, whereas; in situ reduction is performed onto the leached nanocomposite hydrogel to enhance the...
