Reduced Graphene Oxide Functionalized with Cobalt Ferrite Nanocomposites for Enhanced Efficient and Lightweight Electromagnetic Wave Absorption

In this paper, reduced graphene oxide functionalized with cobalt ferrite nanocomposites (CoFe@rGO) as a novel type of electromagnetic wave (EW) absorbing materials was successfully prepared by a three-step chemical method including hydrothermal synthesis, annealing process and mixing with paraffin. The effect of the sample thickness and the amount of paraffin on the EW absorption properties of ...

Antimicrobial Bamboo Materials Functionalized with ZnO and Graphene Oxide Nanocomposites

Bamboo materials with improved antibacterial performance based on ZnO and graphene oxide (GO) were fabricated by vacuum impregnation and hydrothermal strategies. The Zn2+ ions and GO nanosheets were firstly infiltrated into the bamboo structure, followed by dehydration and crystallization upon hydrothermal treatment, leading to the formation of ZnO/GO nanocomposites anchored in the bulk bamboo....

Thermally reduced kaolin-graphene oxide nanocomposites for gas sensing

Highly sensitive graphene-based gas sensors can be made using large-area single layer graphene, but the cost of large-area pure graphene is high, making the simpler reduced graphene oxide (rGO) an attractive alternative. To use rGO for gas sensing, however, require a high active surface area and slightly different approach is needed. Here, we report on a simple method to produce kaolin-graphene...

Reduced graphene oxide/iron carbide nanocomposites for magnetic and supercapacitor applications

Reduced graphene oxide/Fe3C hybrids were prepared through Fe-based intercalation of graphite oxide (GtO). Altering pH (acidic to basic) of aqueous GtO dispersion, the immobilization of Fe-based intercalant bearing amino benzoate groups (IFe) was strongly affected following either the nucleophilic substitution (sample: IGO) or ion exchange path (sample: IGO/b). Subsequent pyrolysis of the interc...
