Wettability of CNW/ITO Micro Structure for Modification of Surface Hydrophilicity

Although the carbon nanowall is a remarkable material in various fields, it generally shows near hydrophobicity. For modification of hydrophilicity, various modification techniques have been utilized, however, most of the techniques adopted a modification to carbon oxide by chemical processing and plasma treatment, which induce carbon lattice defects, causing the decline of the carbon nanowall quality. While we introduce an eco-friendly modification technique that causes non-defect of carbon lattice and maintains intrinsic carbon nanowall properties by depositing ITO on pristine-carbon nanowall for inducing hydrophilicity. The morphology of carbon nanowall (CNW)/ indium tin oxide (ITO) microstructure was examined by FE-SEM, and the functional group and oxygen components of ITO were investigated by analyzing XPS. The contact angles were measured for wettability analysis according to the surface thickness of ITO.
