Abstract
A hydrophilic anti-fog nano paint for endoscope is provided. The paint includes, in parts by weight, 1-10 parts of plant polyphenols, 0.1-2 parts of metal ions, 0.1-0.5 parts of biomass molecules, 10-20 parts of additives and 250 parts of solvents. When coated on a substrate surface and dried, the paint forms a coating in which the plant polyphenols and metal ions combine to form a plant polyphenol-metal nano complex. Together with biomass molecules, the plant polyphenol-metal nano complex produces a hydrophilic nanofilm on the laparoscope surface, thereby enhancing the hydrophilicity of the lens interface.
