Preparation and corrosion behavior of Ni and Ni–graphene composite coatings

Electrical conductivity, thermal conductivity, and rheological properties of graphene oxide-based nanofluids

“…The absorption peak of GO related to conjugation system showed blue shift when compared with that of graphene (270 nm). Reduction of electronic conjugation during oxidation of graphite causes the HOMO and LUMO to be further away in GO and results in a lower k max (Kumar et al 2013). The band gap energy, E g , was estimated from UVVis absorption using Tauc's equation (Goharshadi and Hadadian 2012):…”

Producing cobalt–graphene composite coating by pulse electrodeposition with excellent wear and corrosion resistance

“…Thus, the (1 1 0) preferred orientations still exist. In addition, there is a competition between the nucleation and crystal growth during the growth of the electrodeposited layer [24], the GO nanosheets absorbed on to the cathode surface hinder the crystal growth and increase nucleation sites for reduction of Co ions during deposition, which results in grain refining in the GO/Co composite coating [15].…”

“…Therefore, the composite coatings with superior properties from the codeposition of GO with metal ions can be expected and are feasible. Recently, some works have been done in studying the application of GO in nickel (Ni) electrodeposition [14,15]. Kuang solution with GO sheets in suspension.…”

“…They demonstrated that the thermal conductivity and hardness of the composite film were significantly improved due to the incorporations of GO nanosheets. Kumar et al [15] found that the Ni-graphene composite coating displayed higher corrosion resistance than the bare Ni coating. However, there has no study on the friction and wear property of the composite coating in their study.…”

A corrosion-protective coating based on a solution-processable polymer-grafted graphene oxide nanocomposite

“…Graphene, a single layer of sp 2 -bonded carbon atoms, exhibits a collection of properties such as superior mechanical strength, low chemical reactivity, impermeability to most gases, high transparency and flexibility, and high thermal and electrical conductivity, which make it uniquely suited as a coating material [6][7][8][9][10][11][12][13].…”
