Title:
METHOD FOR SIMULTANEOUSLY ACHIEVING SUPERHYDROPHOBIC AND SUPEROLEOPHOBIC SURFACE ON 1000 SERIES ALUMINUM ALLOY IN ANODIC OXIDATION PROCESS WITHOUT PRE-PATTERNING STEP
Document Type and Number:
WIPO Patent Application WO/2023/195594
Kind Code:
A1
Abstract:
A method for manufacturing a superhydrophilic anodic oxide film on a 1000 series aluminum alloy according to the present invention can manufacture a uniform anodic oxide film even without a pre-patterning step, thereby reducing manufacturing costs, and can impart superhydrophobicity and superoleophobicity to the anodic oxide film due to a coating composition using a cross-linked PDMS derivative represented by chemical formula 1 and an organic solvent in a specific mixing ratio, wherein the coating composition is inexpensive to manufacture and can be applied to the coating of a microstructured oxide film because a coating film thickness can be adjusted from several to several tens of nm.
