Methods of grafting a liquid crystalline coating onto a substrate, and articles comprising a substrate with a liquid crystalline coating are disclosed. The liquid crystalline coatings can be formed by (a) applying a primer layer comprising a Type II photoinitiator to a surface of the substrate, then (b) applying a coating mixture that comprises one or more liquid crystalline monomers to the surface of the substrate, and then (c) irradiating the coating mixture to form the liquid crystalline coating.
