Synthesis of graphene oxide/polyacrylamide composite
To obtain nanofiltration membranes with high-performance in desalination and water purification, membranes of graphene oxide (GO), reduced graphene oxide (rGO) and GO/polyacrylamide (PAM) are prepared by a vacuum filtration method. This method is conducted in aqueous solution without any organic solvents. The graphene-based membranes (GBMs) are characterized by UV–visible spectroscopy, Fourier-transform infrared spectroscopy, transmission electron microscopy, atomic force microscopy
Graphene Oxide is an insulative materials, but its chemical treatment by light , heat or Chemical reduction can restore most properties of pristine Graphene. Due to high affinity in water molecules by these group, GO is hydrophilic and can be desolved in water. Application of Graphene Oxide: Water purification, Polymers
Graphene oxide (GO)/polyacrylamide (PAM) composite
Composite hydrogels were prepared in the mixtures of graphene oxide (GO) and polyacrylamide (PAM) in water. The gelation behavior of the hydrogels was studied in detail.
GO/polyacrylamide (PAM) composite hydrogel was fabricated through in situ acrylonitrile polymerization in GO-water solution (Liu et al., 2012). The tensile strength of GO/PAM hydrogel was about 4.5 times higher than the pure PAM hydrogel, and the breaking elongation was 30 times exceeded than the PAM, but the content of GO was only 0.0079 wt%.

Graphene Improves the Biocompatibility of Polyacrylamide
In this direction, many efforts have been made to fabricate hybrid graphene-based hydrogels with enhanced properties, mainly using graphene oxide (GO) 24, 25, graphene oxide peroxide (GOP) 26, or
To improve the dispersibility of graphene oxide (GO) in solvents, the grafting of polyacrylamide (PAM) from the GO surface was performed by redox polymerization system. The hydrophilic nature and high polarity of PAM have made effective dispersion of GO. Then, Pd nanoparticles (Pd NPs) were anchored on the surface of polyacrylamide grafted reduced graphene oxide nanosheets (PAM-g-rGO/Pd).
