    Abstract: The present invention pertains to a process for manufacturing a fluoropolymer hybrid organic/inorganic composite, said process comprising: (i) providing a mixture comprising: (a) at least one fluoropolymer comprising recurring units derived from at least one fluorinated monomer and at least one comonomer [comonomer (MA)] comprising at least one hydroxyl group [polymer (F)]; (b) at least one metal compound [compound (M)] of formula (I): X4-mAYm, (I) wherein m is an integer from 1 to 4, and, according to certain embodiments, from 1 to 3, A is a metal selected from the group consisting of Si, Ti and Zr, Y is a hydrolysable group, X is a hydrocarbon group, optionally comprising one or more functional groups; (c) a liquid medium comprising at least one compound selected from the group consisting of a diester of formula (IIde) and an ester-amide of formula (IIea): R1—OOC—Zde—COO—R2 (IIde) R1—OOC—Zea—CO—NR3R4 (IIea) wherein: R1 and R2, equal to or different from each other, are independently selected from the group consisting of C1-C20 hydrocarbon groups, R3 and R4, equal to or different from each other, are independently selected from the group consisting of hydrogen, C1-C36 hydrocarbon groups, possibly substituted, being understood that R3 and R4 might be part of a cyclic moiety including the nitrogen atom to which they are bound, said cyclic moiety being possibly substituted and/or possibly comprising one or more than one additional heteroatom, and mixtures thereof, Zde and Zea, equal to or different from each other, are independently a linear or branched C3-C10 divalent alkylene group; and (d) optionally, at least one electrolytic salt (ES); (ii) reacting at least a fraction of hydroxyl groups of said comonomer (MA) of said polymer (F) with at least a fraction of the hydrolysable groups Y of said compound (M), so as to obtain a grafted fluoropolymer [polymer (Fg)] comprising one or more pendant groups of formula —Ym-1AX4-m; and (iii) hydrolysing and/or polycondensing said compound (M) and/or said pendant groups of formula —Ym-1AX4-m to yield a liquid mixture comprising the fluoropolymer hybrid organic/inorganic composite and incorporating said liquid medium.
