Controlled Growth of Tungsten Oxide Films by Hydrothermal Synthesis for Underwater Superoleophobicity Regulation
Through controlling the pH of the precursor, we have achieved creatively controllable growth of tungsten oxide on stainless steel meshes with different morphologies via a simple hydrothermal method. Consequently, under the synergistic action of micro/nanostructures and the intrinsic hydrophilic property, the underwater superoleophobicity of tungsten oxide films can also be regulated successfully, which is helpful in the design of functional nanomaterials with various morphologies.
