This invention belongs to the field of
coating materials, specifically including an anti-
fog coating, its preparation method, and its application. The raw materials for preparing the anti-
fog coating specifically include the following components: photothermal nanoparticles,
polyvinyl alcohol,
phytic acid solution,
glutaraldehyde solution, and deionized water in a ratio of 0.6 kg: 15 kg: 20 L: 10 L: 150 L. The photothermal nanoparticles are added to deionized water and ultrasonically dispersed to obtain a uniform
nanoparticle suspension.
Polyvinyl alcohol is added to this suspension, and the
system is placed in a high-temperature water bath and magnetically stirred until completely dissolved. Then, an appropriate amount of
phytic acid solution is added, and ultrasonically dispersed until the
phytic acid is fully dissolved. Next,
glutaraldehyde solution is added to the mixture, and magnetically stirred to allow the
glutaraldehyde to fully react with the
system components, obtaining a stable and dispersed coating. Finally, the coating is uniformly applied to the surface of a glass substrate and allowed to air dry naturally in a ventilated area. The resulting coating effectively inhibits the formation of
fog droplets and accelerates the dissipation of existing fog droplets, while maintaining good light
transmittance.
