Composites based on chitosan- and gold-modified carbon fibers

We report the fabrication of composite materials containing gold particles deposited on the surface of carbon fibers, in particular, immobilized in films of chitosan, a natural biopolymer. The fabrication process involves gold-chitosan electrocodeposition on unmodified fibers or gold deposition on c...

Description
Summary:We report the fabrication of composite materials containing gold particles deposited on the surface of carbon fibers, in particular, immobilized in films of chitosan, a natural biopolymer. The fabrication process involves gold-chitosan electrocodeposition on unmodified fibers or gold deposition on chitosan-carbon materials used as electrodes. Scanning electron microscopy, energy dispersive X-ray analysis, and X-ray diffraction results are used to gain insight into the role of ion exchange, complexation, and electrochemical factors in the formation of the composites.
