Superhydrophobic and self-cleaning powders having micron-scale diameter and nano-scale surface roughness and fabrication method thereof
The invention discloses nano/micron binary structured powders for superhydrophobic, self-cleaning applications. The powders are featured by micron-scale diameter and nano-scale surface roughness. In one embodiment, the average diameter is about 1-25 μm, and the average roughness Ra is about 3-100 nm. The nano/micron binary structured powders may be made of silica, metal oxide, or combinations thereof.
