    摘要: Described herein is composite article comprising a substrate; and on at least one face of the substrate a multilayered coating disposed thereon. The multilayered coating comprises (i) an abrasion-resistant layer adjacent to the substrate, wherein the abrasion-resistant layer comprises inorganic oxide nanoparticles and a polymer binder; and (ii) an antireflection layer adjacent to the abrasion-resistant layer opposite the substrate, wherein the antireflection layer comprises a fluorosilane polymer, wherein the fluorosilane polymer comprises: at least one monomeric unit A represented by the formula (I) wherein R1 represents H or methyl, L1 represents a covalent bond or a divalent aliphatic group having from 1 to 10 carbon atoms, each Y1 independently represents a hydrocarbyl group having from 1 to 6 carbon atoms, each Y2 independently represents a hydrolyzable group, g is 0, 1, or 2; and at least one divalent monomeric unit B represented by the formula (I) wherein R2, R3, and R4 represent H, methyl, trifluoromethyl, or F, wherein at least one of R2, R3, and R4 is F, Rf 1 represents a covalent bond or a divalent group selected from the group consisting of -(CF2O)a-, -(CF2CF2O)b-,-(CF2CF2CF2O)c-,-(CF2CF2CF2CF2O)d-,-(CF2CF(CF3)O)e-, and combinations thereof, wherein a, b, c, d, and e represent integers in the range of from 0 to 130, and wherein 1 ≤ a + b + c + d + e ≤ 130, and Rf 2 is a perfluoroalkyl group.
