Synthesis and characterization of Au-immobilized nanoparticles onto cellulose-ethylenediamine-grafted reduced graphite oxide sheets
The synthesis of Au-immobilized nanoparticles onto graphite oxide sheets (GO) having attached cellulose fibrous was investigated as well as their electrical properties. The synthesis of GO-based materials was accomplished in two steps through ethyleneamine nucleophilic addition onto carboxylic acid and epoxide groups located on the GO sheets' surface followed by the grafting of chloro-cellulose onto the activated graphite oxide sheets. Finally, the corresponding material was doped with gold nanoparticles after a chemical reduction and their electrical properties were studied as a function of temperature. (C) 2016 Elsevier B.V.
