Title:
METHOD FOR FORMING SIMULTANEOUSLY SUPERHYDROPHOBIC AND SUPEROLEOPHOBIC SURFACE ON 6000-SERIES ALUMINUM ALLOY OMITTING PRE-PATTERNING STEP IN ANODIZATION PROCESS
Document Type and Number:
WIPO Patent Application WO/2023/191242
Kind Code:
A1
Abstract:
A method for manufacturing a superhydrophilic anodized film on a 6000-series aluminum alloy, according to the present invention, enables the manufacture of a uniform anodized film even without a pre-patterning step, thus reducing manufacturing costs, and can impart superhydrophobicity and superoleophobicity to the anodized film due to a coating composition using a crosslinked PDMS derivative represented by chemical formula 1 and an organic solvent in a specific mixing ratio, wherein the coating composition is prepared at low cost and enables adjustment of the thickness of a coating film to several nanometers to several tens of nanometers, and thus can also be applied to the coating of microstructured oxide films.
