Antifogging coatings with superhydrophilic performance by manipulating composition and structure have obtained significant consideration over recent years attributed to their ability readily form a thin water film, which does not deteriorate light transmission. In this work, an advanced organic-inorganic nonhomogeneous antifogging coating has been successfully fabricated. The bottom layer was comprised of silica nanoparticles, forming the three-dimensional (3D) network skeleton via condensation silicon hydroxyl, enhanced resistance coating; while top formed silica-polymer nanocomposite, conferred good capability due its abundant hydrophilic groups. composite exhibited size-dependent surface properties, when average particle size 10 nm, nanocomposite remarkable frost-resisting properties. Furthermore, also showed higher stability than pure polymer coating, it remained outstanding after soaking in for 6 hours, or 120 hours exposure UV irritation.
