摘要 A series of photosensitive hydrophilic agents (T20) comprising Tween‐20, isophorone diisocyanate, and 2‐hydroxyethyl methacrylate moieties were synthesized and used in the preparation of antifog/frost resistant (AFF) hard coatings on plastic substrates. By means of a hydrophilic/hydrophobic bilayer design, the prepared coatings demonstrated not only AFF property but also water resistibility. The bottom layer is an organic–inorganic composite consisting of SiO2 nanoparticles embedded in a polymeric network of crosslinked dipentaethritol hexaacrylate. The AFF layer incorporates T20 in the formulations and links covalently with the bottom layer through a UV‐curing polymerization process. Various methods, for example, FTIR, SEM, contact angle, and steam/defrosting tests, were employed to characterize the prepared coatings. Optimally, the coatings were found to be transparent, strong (4H, pencil hardness), adhering perfectly (level 5B) to the poly(methyl methacrylate) substrate, and could be soaked in water for 24 h at 25 °C without losing hydrophilicity (contact angle ~0°) or antifogging capability.
