Can graphene oxide be used as a gelator?

Gelation behavior Graphene oxide (GO) have plenty of oxygen-containing groups, which can be used as a gelator to prepare composite hydrogel. Polyacrylamide (PAM), a soluble polymer, can be used as a cross-linker to form composite hydrogels with other gelator.

Can polyacrylamide be used as a cross-linker to form composite hydrogels?

Polyacrylamide (PAM), a soluble polymer, can be used as a cross-linker to form composite hydrogels with other gelator. In this paper, GO/PAM composite hydrogels were obtained by mixing appropriate amounts of PAM and GO solution in water, and the photo of the sample was shown in Fig. 1.

What is graphene composite hydrogel?

Compared to traditional hydrogels, the graphene composite hydrogels not only have high mechanical strength and toughness, but also possess outstanding electrical and thermal performance, which immensely broaden the hydrogels applications , , , .

Are graphene oxide hydrogels biocompatible?

Biocompatible swelling graphene oxide reinforced double network hydrogels with high toughness and stiffness Conductive graphene oxide hydrogels reduced and bridged by l-cysteine to support cell adhesion and growth J. Mater. Chem.

Does go/polyacrylamide (PAM) interact with a polyacrylamide composite hydrogel?

In this article, GO/polyacrylamide (PAM) composite hydrogel was prepared, in which the PAM acted as the cross-linker and the main driven force was various noncovalent interactions. The effect of the concentration of PAM and GO to the gelation were studied in detail.

Is graphene oxide a good filler for hydrogels?

Graphene oxide (GO) is a well-known two-dimensional water-dispersible nanosheet, and believed as one of the best fillers to improve the mechanical properties of hydrogels [, , ].
