LASER ABLATION FOR COPPER OXIDE NANOWIRES GROWTH AND ITS APPLICATION FOR OIL-WATER SEPARATION
… the CuO NWs array on a Cu foil was achieved with laser-fabricated microholes through pulsed 1064 nm laser texturing. Microhole-lined hierarchical functional surfaces are created in a controllable and catalyst-free process. The resulting superhydrophilic nano-textured surface demonstrated efficient …
