Grafted Carbazole-Assisted Electrodeposition of Graphene Oxide

The electrodeposition of graphene oxide (GO) by covalently linked electroactive :monomer, carbazole (Cbz) is first demonstrated herein. This is based on the electropolyrnerization and electiodeposition of covakntly linked Cbz units when a potential is applied. During the electrochemical process, the Cbz groups electropolymerize and carry the GO nanosheets as it electiodeposits on the substrate. Moreover, the GO-Cbz sheets selectively deposit onto the conducting regions of the substrate, which demonstrates its promise for the fabrication of electropattemed graphene-based devces. In addition, GO-Cbz is a promising material for the fabrication of nanocomposite Coatings for anticorrosion application. In as little as 1 wt % GO-Cbtz loacling, a protection efficiency as high as 95.4% was achieved.
