Abstract
A reduced graphene oxide (rGO)/chitosan oligomers (CSO)/silver nanoparticle (AgNPs) composite was designed and prepared via a self-assembly process with rGO through a microwave assisted method. The material, isolated as a nano-crystalline graphenic material, was characterized by ATR-FTIR and UV-Vis spectroscopies, X-ray powder diffraction, TEM microscopy, and energy dispersive X-ray spectroscopy. The nano-rGO/CSO/AgNPs composite can be described as a biopolymer in which AgNPs have been anchored on the surface of CSO-functionalized graphitic rGO sheets.
