▎ 摘　　要

NOVELTY - Anti-fog coating comprises urethane acrylate, a photoinitiator and a fluorine-containing temperature-sensitive nanomaterial. The fluorine-containing temperature-sensitive nanomaterial comprises two-dimensional nanomaterial and an N-isopropylacrylamide-based polymer layer coated on the two-dimensional nanomaterial. The fluorine-containing group is connected to the N-isopropylacrylamide-based polymer layer. USE - The anti-fog coating is useful in medical appliance, preferably an endoscope or laparoscope (claimed). ADVANTAGE - The anti-fog coating has stable coating properties, good water resistance and reliability, and can fully meet the long-term application requirements of the anti-fogging coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the anti-fog coating, comrpising mixing and uniformly dispersing polyurethane acrylate, a photoinitiator and a fluorine-containing temperature-sensitive nanomaterial.
