Abstract Perfluorinated poly(2,3,4,5,6-pentafluorostyrene) (PPFS) and PPFS-functionalized silica (nano)particles derivatives were synthesized and further combined to prepare organic/inorganic (nano)composite films. First, the post-polymerization modification of PPFS with 1H,1H,2H,2H-perfluorodecanethiol (PFDT) via a versatile thiol-para-fluoro coupling was optimized to synthesize fluoropolymers PPFS-PFDT with randomly distributed perfluorinated groups, which hydrophobicity was tuned by the degree of substitution (DS). Then, the coupling reaction was successfully applied to the perfluorination of PPFS-functionalized fumed silica. A library of fluorinated polymers (PPFS or PPFS-PFDT with different DS) were combined with modified silica to elaborate multiscale-textured nanocomposite films exhibiting self-cleaning properties.

通过硫醇-对氟偶联控制聚（2,3,4,5,6-五氟苯乙烯）（PPFS）和 PPFS 功能化气相二氧化硅的全氟化：朝向自清洁（纳米）复合膜的设计

摘要 合成全氟聚（2,3,4,5,6-五氟苯乙烯）（PPFS）和 PPFS 功能化二氧化硅（纳米）粒子衍生物，并进一步结合制备有机/无机（纳米）复合薄膜。首先，通过多功能硫醇-对氟偶联对 PPFS 与 1H,1H,2H,2H-全氟癸硫醇 (PFDT) 进行聚合后改性，以合成具有随机分布的全氟化基团的含氟聚合物 PPFS-PFDT，其疏水性由取代度 (DS)。然后，偶联反应成功地应用于PPFS功能化气相二氧化硅的全氟化。氟化聚合物库（具有不同 DS 的 PPFS 或 PPFS-PFDT）与改性二氧化硅结合，以精心制作具有自清洁性能的多尺度纹理纳米复合薄膜。
