Abstract: Coating compositions are described including silica nanoparticles functionalized with an alkenyl silane, a dispersing agent, and a compound including a polyethylene oxide segment containing at least one hydroxyl group, at least one silane, and optionally a hydrophobic group. The coating compositions further include at least two multifunctional (meth) acrylate monomers. Also described are articles including the dried and cured coating composition disposed on a substrate. The articles exhibit anti-fog characteristics and often also mechanical durability.
