The present invention pertains to a fluoropolymer hybrid organic/inorganic composite, to a film comprising said fluoropolymer hybrid organic/inorganic composite and to uses of said film in various applications, especially in electrochemical and in photo-electrochemical applications. 1. A process for manufacturing a fluoropolymer hybrid organic/inorganic composite (FH) , said process comprising: [ {'br': None, 'sub': 4-m', 'm, 'XM(OY)\u2003\u2003(I)'}, 'a pre-gel compound (MP) obtainable by at least partial hydrolysis and/or polycondensation, in the presence of a liquid medium, of at least one metal compound (M) of formula (I), 'wherein M is a metal selected from the group consisting of Si, Ti and Zr, X and Y, equal to or different from each other and at each occurrence, are selected from hydrocarbon groups, optionally comprising one or more functional groups, and m is an integer comprised between 1 and 4, and', 'at least one polymer (FF), wherein polymer (FF) is at least one functional fluoropolymer comprising at least one hydroxyl group;, '(i) providing a pre-composite (FP) by processing in molten phase [ {'br': None, 'sub': 2', 'A', 'n', 'B, 'HO—(CHCHRO)—R\u2003\u2003(II)'}, 'at least one poly(alkylene oxide) (PAO) of formula (II), {'sub': A', '1', '5', 'B', '3, 'wherein Ris a hydrogen atom or a C-Calkyl group, Ris a hydrogen atom or a —CHalkyl group and n is an integer comprised between 2000 and 40000,'}, 'at least one metal salt (M),', 'optionally, at least one fluoropolymer [polymer (F)], equal to or different from the polymer (FF), and', 'optionally, one or more inorganic fillers; and, '(ii) providing a composition by compounding the pre-composite (FP) provided in step (i) with(iii) processing in molten phase the composition provided in step (ii).2. The process according to claim 1 , wherein the polymer (FF) comprises at least 0.01% by moles of recurring units derived from at least one monomer (OH).3. The process according to claim 1 , wherein the polymer (FF) ...
