    Abstract: The present invention pertains to a process for manufacturing a solid composite layer, said process comprising the following steps: (i) providing a mixture comprising: at least one functional fluoropolymer comprising at least one hydroxyl group [polymer (F)], at least one metal compound of formula (I) [compound (M)]: X4-mAYm wherein X is a hydrocarbon group, optionally comprising one or more functional groups, m is an integer from 1 to 4, A is a metal selected from the group consisting of Si, Ti and Zr, and Y is a hydrolysable group selected from the group consisting of an alkoxy group, an acyloxy group and a hydroxyl group, and at least one inorganic filler material [filler (I)] in an amount of from 50% to 95% by weight, with respect to the total weight of said polymer (F) and said filler (I); (ii) reacting at least a fraction of said hydroxyl group(s) of at least one polymer (F) with at least a fraction of said hydrolysable group(s) Y of at least one compound (M), so as to provide a fluoropolymer composition comprising at least one grafted fluoropolymer [polymer (Fg)] comprising pendant groups of formula -Ym-1-AX4-m, wherein m, Y, A and X have the same meaning as defined above; and (iii) processing the fluoropolymer composition obtained in step (ii), so as to obtain a solid composite layer. The invention also pertains to the solid composite fluoropolymer layers obtained from said process and to uses of said solid composite fluoropolymer layers as separators in electrochemical devices.
