Controlled perfluorination of poly(2,3,4,5,6-pentafluorostyrene) (PPFS) and PPFS-functionalized fumed silica by thiol-para-fluoro coupling: Towards the design of self-cleaning (nano)composite films

Synthesis and surface properties of amphiphilic fluorine‐containing diblock copolymers

“…Earlier, we have established that cotton/polyester fabric treated with PHEMA absorbs rapidly both water and DI due to capillary effects 26 . The treatment of cotton/polyester fabric with PPFS made its surface hydrophobic with the θ Н 2 О = 102 ± 2° and θ CH 2 I 2 = 80 ± 2° (Table 4), which are rather close to the ones determined by Yin et al 11 for PPFS films.…”

“…A lot of approaches for both applying roughness and structuring the surface as well as for covering the surface with different compounds with low surface energy have been proposed. Up to now, a variety of rough surfaces have been prepared using chemical etching, 6 lithography, 7 laser microstructuring, 8 applying nanoparticles, [9][10][11][12] or nanofibers 13 of different nature, mechanical treatment such as pressing rough templates to the substrate 14 and many other methods, such as depositing candle soot on a substrate. 15 Substances containing nonpolar groups such as CH 2 , CH 3 , CF 2 , CF 3 , can be used before or after roughening to achieve low surface energy.…”

Azide–para-Fluoro Substitution on Polymers: Multipurpose Precursors for Efficient Sequential Postpolymerization Modification

“…Unlike other electrophilic groups (such as the halobenzyl functionality), the PFB group is not prone to unwanted hydrolysis or alcoholysis . Not surprisingly, the recent years have seen a growing interest , in the post-synthesis modification of PFB-functional polymers, such as poly­(2,3,4,5,6-pentafluorostyrene) (pPFS) and poly­(2,3,4,5,6-pentafluorobenzyl methacrylate) (pPFBMA) with thiols, including for the cross linking of copolymer nanoparticles, the modification of surfaces, , the manipulation of conjugated polymers, , and the synthesis of polymer networks, stimulus-responsive polymers, bifunctional copolymers, − and glycopolymers. , Recently, our group has showed that pPFBMA can also be modified with amines and carbonylthiolates, though with less efficiency . Efficient chemistry on polymer-bound PFB groups is thus largely limited by the availability of functional thiols.…”

Synthesis and Solid-State Properties of PolyC3 (Co)polymers Containing (CH2–CH2–C(COOR)2) Repeat Units with Densely Packed Fluorocarbon Lateral Chains

“…Qualitatively comparing the above solubility data with other polymers described in the literature having a similar fluorinated lateral chain suggests that 4 is noticeably less soluble. Polyacrylates of different types, − poly­(vinyl ether)­s, , poly­(2-oxazoline)­s, and poly­( para -substituted tetrafluorostyrene), all exhibit solubility at room temperature in organic solvents such as chloroform and, in the few cases they do not (mostly in the acrylate series), are soluble in fluorinated solvents. One exception to the above rule might be the substituted polymethylene (PolyC 1 ) discussed in the Introduction although its solubility in fluorinated solvents has not been reported yet …”
