The electrodeposition of graphene oxide (GO) by covalently linked electroactive monomer, carbazole (Cbz) is first demonstrated herein. This is based on the electropolymerization and electrodeposition of covalently linked Cbz units when a potential is applied. During the electrochemical process, the Cbz groups electropolymerize and carry the GO nanosheets as it electrodeposits 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 electropatterned graphene-based devices. In addition, GO-Cbz is a promising material for the fabrication of nanocomposite coatings for anticorrosion application. In as little as 1 wt % GO-Cbz loading, a protection efficiency as high as 95.4% was achieved.
本文首次展示了通过共价连接的电活性单体咔唑（Cbz）电沉积氧化石墨烯（GO）的方法。这是基于施加电势时共价连接的Cbz单元的电聚合和电沉积。在电化学过程中，Cbz基团发生电聚合，并在其电沉积到基底上时携带GO纳米片。此外，GO-Cbz片选择性地沉积在基底的导电区域上，这表明其在制造电图案化石墨烯基器件方面具有潜力。此外，GO-Cbz是用于制造防腐应用纳米复合涂层的有前景的材料。在仅1 wt%的GO-Cbz负载量下，实现了高达95.4%的保护效率。
