“…The refractive indexes of the MTQ-F resin and A 3 Si 4 are 1.4355 and 1.4493, respectively. The lowered MTQ-F refractive index against A 3 Si 4 is due to the perfluorinated chains which reduce the refractive index . As described above, when the A 3 Si 4 content is increased to more than 60 wt %, the uniformity of the coating surface deteriorates significantly in the range of a few micrometers, resulting in a refractive index difference between the coating surface and the substrate.…”

“…The lowered MTQ-F refractive index against A 3 Si 4 is due to the perfluorinated chains which reduce the refractive index. 39 As described above, when the A 3 Si 4 content is increased to more than 60 wt %, the uniformity of the coating surface deteriorates significantly in the range of a few micrometers, resulting in a refractive index difference between the coating surface and the substrate. Therefore, the change in transmittance of MTQ-F/A 3 Si 4 coatings may be due to a combination of coating roughness increase and light scattering caused by changes in the refractive index of the coating surface.…”

Transparent, hard, and flexible multifunctional coatings have a wide range of applications; however, most of them need organic solvents. Here, we present a solvent-free and UV-cured coating made from fluorinated epoxy MTQ silicone resin combined with branched triepoxy siloxane as the reactive diluent. After UVinitiated ring-opening polymerization in the presence of a triarylsulfonium hexafluoroantimonate catalyst, the resultant cured coating exhibits high transparency (∼92%, 550 nm), pencil hardness (7H), and flexibility (1 mm bending diameter) due to the formed organic−inorganic nanostructures in a highly cross-linked network. The triepoxy siloxane significantly reduces the viscosity before curing and increases cross-link density of the coating. The coating without any volatile content shows a smooth surface with low roughness (R q = 0.46 nm) and delivers an anti-smudge ability owing to perfluorinated chains inherited from the MTQ resin. Furthermore, even after 3000 abrasion cycles, the coating still has a water contact angle greater than 90°, displaying excellent wear resistance. Our work provides a promising way to access high-performance multifunctional coatings in a more sustainable manner.
