The effective reduction of graphene oxide films using RF

2021/3/2Graphene oxide (GO) is an oxygenated derivative of graphene. It has abundant functional groups of oxygen and can be exfoliated and dispersed easily in different solvents including water [ 2, 3 ]. Graphene and its derivatives have enormous expectations for usage in many applications, while its low electrical conductivity is still a challenging problem.

Graphene has attracted great interest for its excellent mechanical, electrical, thermal and optical properties. It can be produced by micro-mechanical exfoliation of highly ordered pyrolytic graphite, epitaxial growth, chemical vapor deposition, and the reduction of graphene oxide (GO).

Tailoring drug release rates in hydrogel

Biocompatible graphene oxide (GO) is increasingly used in hydrogels to chemically immobilize therapeutic agents, or to modify mechanical and thermal properties. GO can provide several therapeutic advantages such as the ability to carry bioactive molecules into hydrogels [ 1 ], as well as providing structural properties leading to increased drug-loading efficiency [ 2 ].
