“…The preparation of this fluoroalkene was achieved in a two-step procedure starting from a telomerisation reaction [3] of VDF with 1-iodo-perfluoro-n-hexane followed by the dehydroiodination of the monoadduct (C 6 F 13 CH 2 CF 2 I), as shown in Scheme 2.…”

“…As a matter of fact, the appropriate choice of the comonomer enables one to bring complementary properties [3]: cyclohexyl group for the solubility, hydroxy and epoxy functions for curability, carboxylic group for adhesion, amido bridge for mechanical properties and perfluorinated group for enhanced surface properties.…”

“…Although many copolymerisations of VDF with a wide variety of hydrogenated [5,6] or fluorinated comonomers [3] have already been successfully achieved, that of VDF with 2H-perfluoroalkenes have been scarcely investigated. To our knowledge, the only survey concerns the use of 2-hydropentafluoropropylene (PFP) yielding original fluorinated copolymers studied by the 3M [7] and the Montedison [8] companies to circumvent VDF/hexafluoropropylene elastomers (called Daiel 1 , Tecnoflon 1 , Viton 1 or Fluorel 1 ) [1,[9][10][11][12].…”

“…Fluorinated copolymers [1][2][3] are attractive for their exceptional properties and, in spite of their high price, show a lower crystallinity-rate than that of the fluorohomopolymers [4]. As a matter of fact, the appropriate choice of the comonomer enables one to bring complementary properties [3]: cyclohexyl group for the solubility, hydroxy and epoxy functions for curability, carboxylic group for adhesion, amido bridge for mechanical properties and perfluorinated group for enhanced surface properties.…”

The synthesis and the radical copolymerisation of 2-hydroperfluorooct-1-ene (HPO) with vinylidene fluoride (VDF), initiated by tertiobutyl peroxypivalate (TBPPI) at 75 8C, are presented. That fluorinated alkene (HPO) was synthesised in two steps starting from the thermal or redox telomerisation of VDF with C 6 F 13 I (after purification of the monoadduct compound by rectification) followed by a dehydroiodination in the presence of various alkalies. Their influences are discussed toward the yield of the reaction. The compositions of the resulting random-type copolymers were calculated by means of 19 F NMR spectroscopy and allowed one to quantify the respective amounts of each monomeric unit in the copolymer. From the Tidwell and Mortimer method, the reactivity ratios (r i ) of both comonomers for this copolymerisation were determined showing a higher incorporation of VDF: r VDF = 12.0 AE 3.0 and r F 2 C¼CHC 6 F 13 ¼ 0:9 AE 0:4 at 74 8C. #

“…Fluorinated polymers [1][2][3][4][5] are interesting materials thanks to their outstanding properties, such as their thermal stability, chemical inertness (to solvents, oils, water, acids and bases), low refractive index, permittivity, dissipation factor and water absorptivity, in addition to their excellent weatherability, durability and resistance to oxidation. Actually, two families of fluorinated polymers can be considered: (i) those where the fluorinated groups are located in the polymer backbone, which are chemically inert, thermally stable and have low refractive index and low dielectric constant, and (ii) those containing a fluorinated dangling group that enhances the surface properties.…”

The structure, thermal properties and surface wettability of a novel alternating poly(VCN-alt-FAVE8) copolymer based on vinylidene cyanide (VCN) and perfluorooctyl ethyl vinyl ether (FAVE8) were investigated via both temperature-variable wide-angle X-ray powder diffraction (WAXD) and thin-film WAXD using a small angle incidence synchrotron radiation source, differential scanning calorimetry and contact angle measurements, respectively. The results of the WAXD and thin-film WAXD indicated that the alternating copolymer possessed a smectic liquid-crystalline phase at ambient temperature with a couple of fluoroalkyl side chains forming a bilayer with a 3.24 nm spacing and that the fluoroalkyl side chains in a thin-film on a Si wafer align perpendicularly to the surface. The isotropization temperature of the alternating copolymer was 150 1C, which was higher than the 29.5 1C for the poly(FAVE8) homopolymer. The spin-coated poly(VCN-alt-FAVE8) copolymer thin-film yielded high static contact angles for both water and oil similar to those for poly(perfluorooctyl ethyl acrylate), which is known as a superhydrophobic polymer. Dynamic contact angle and X-ray photoelectron spectroscopy measurements in both the dry and hydrated states suggested that the polar cyano and ether groups are enriched at the surface in the wet state, and this reorganization of the surface polar groups caused a large hysteresis of the contact angle.

In this study, a new phthalonitrile derivative namely 4‐[(2,4‐difluorophenyl)ethynyl]phthalonitrile (1) and its metal phthalocyanines (2 and 3) were synthesized. The resultant compounds were conjugated to silver nanoparticles and characterized using transmission electron microscopy (TEM) images. The biological properties of compounds (1–3), their nanoconjugates (4–6), and silver nanoparticles (7) were examined for the first time in this study. The antioxidant activities of biological candidates (1–7) were studied by applying the 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radical scavenging assay. The highest antioxidant activity was obtained 97.47 % for 200 mg/L manganese phthalocyanine‐silver nanoconjugates (6). The antimicrobial and antimicrobial photodynamic therapy (APDT) activities of biological candidates (1–7) were examined using a micro‐dilution assay. The highest MIC value was obtained 8 mg/L for nanoconjugate 6 against E. hirae. The studied compounds and their silver nanoconjugates exhibited high APDT activities against all the studied microorganisms. The most effective APDT activities were obtained 4 mg/L for nanoconjugates (5 and 6) against L. pneumophila and E. hirae, respectively. All the studied biological candidates displayed high cell viability inhibition activities against E. coli cell growth. The biofilm inhibition activities of the tested biological candidates were also investigated against S. aureus and P. Aeruginosa. Biological candidates (1–6) can be considered efficient metal nanoparticle‐based materials for multi‐disciplinary biological applications.
