SURFACE TREATMENT COMPOSITION CAPABLE OF IMPARTING UNDERWATER SUPEROLEOPHOBICITY

摘要

The invention relates to a surface treatment composition containing functionalized micro/nanoparticles, said functionalized micro/nanoparticles comprising a core particle having a diameter in the range of 50-5,000 nm, said core particle carrying a plurality of covalently bound silane polymer residues on the surfacewherein the hydrophilic polymer residue is residue of a polymer selected from polyethylene glycol, polypropylene glycol, polyvinyl alcohol, polyacrylamide, polyoxazoline, polyethyleneimine, acrylic polymers, poly(vinylpyrrolidone), polysaccharides, chitosan and copolymers thereof. This surface treatment composition can be used to impart underwater superoleophobicity to surfaces by treating such surfaces with the surface treatment composition. The invention also relates to the use of the aforementioned surface treatment composition for imparting underwater superoleophobicity to a surface, for imparting stain repellency to a surface and/or for imparting antimicrobial properties to a surface, said use comprising treating the surface with the treatment composition.
