Abstract: The invention pertains to a process for manufacturing a fluoropolymer hybrid organic/inorganic composite comprising: (i) partially hydrolysing and/or polycondensing, in the presence of an aqueous medium, a metal compound of formula (I): X4-mAYim, wherein X is a hydrocarbon group, Y is a hydrolysable group selected from the group consisting of an alkoxy group, an acyloxy group and a hydroxyl group, A is a metal selected from the group consisting of Si, Ti and Zr, and m is an integer from 1 to 4, so as to obtain an aqueous medium comprising a pre-gelled metal compound comprising one or more inorganic domains consisting of ≡A-O-A≡ bonds and one or more residual hydrolysable groups Y [compound (M)], and then (ii) reacting in the molten state at least a fraction of hydroxyl groups of a functional fluoropolymer [polymer (F)] with at least a fraction of hydrolysable groups Y of said pre-gelled metal compound [compound (M)], so as to obtain a fluoropolymer hybrid organic/inorganic composite. The invention also pertains to uses of said fluoropolymer hybrid organic/inorganic composite in several applications.
Abstract translation: 本发明涉及一种制备含氟聚合物杂化有机/无机复合材料的方法，包括：（i）在含水介质存在下部分水解和/或缩聚式（I）的金属化合物：X4-mayim，其中X 是烃基，Y是选自烷氧基，酰氧基和羟基的可水解基团，A是选自Si，Ti和Zr的金属，m是从 1至4，以获得包含由≡AOA≡键和一个或多个残余可水解基团Y [化合物（M）]组成的一种或多种无机域的预凝胶金属化合物的水性介质，然后（ii） 在熔融状态下使至少一部分所述预胶化金属化合物[化合物（M）]的可水解基团Y的官能含氟聚合物[聚合物（F）]的羟基的至少一部分反应，以获得 含氟聚合物杂化有机/无机复合材料 e。 本发明还涉及在几种应用中所述含氟聚合物杂化有机/无机复合材料的用途。
