“…The most thermally stable homopolymer M2 C10 ( T 10% ‐ 10 K/min: 360 °C in N 2 and 292 °C in air—Figure ) showed higher thermal stability than crosslinked PFPAEs with acrylate bonds ( T 10% ‐ N 2 = 256–280 °C) . They were also comparable to materials based on stronger triazole bonds under air ( T 10% = 305 and 336 °C) containing PFPAEs and perfluoroalkyl chains . However, the maleimides obviously showed a faster degradation kinetic in presence of air and seemed to be more sensitive to oxidation degradation even if these non‐crosslinked polymers provided good results in terms of thermal stability.…”

Perfluoropolyalkylethers derived from hexafluoropropylene oxide were functionalized with maleimide groups. Irradiated by UV‐light, the new maleimide macromonomers demonstrated very fast polymerization kinetics with a curing time as fast as 8 s. The effect on photopolymerization of different features such as the molecular weight of the fluorinated chain and the chain length of the hydrogenated spacer were studied, as well as the influence of the type of photoinitiator and the presence of air. Thermal and surface properties of the UV‐cured polymers were examined and were typical to fluoropolymers in view of water–oil repellent coatings. © 2018 Wiley Periodicals, Inc. J. Polym.

“…As 8.5% of the HFP units are adjacent to TFE, 1.8 mol % of all monomers are located in HFP–TFE diads, and 0.9 mol % of all monomers are TFE units located next to HFP units. Twenty‐one mole percentage of all monomers are TFE units that form either TFE–TFE–TFE triads or are located next to a VDF unit . However, the ppm resolution we could achieve does not allow further quantification.…”

Random THV terpolymers consisting of tetrafluoroethylene (TFE), hexafluoropropylene (HFP), and vinylidene fluoride (VDF) are viable alternatives to polytetrafluoroethylene (PTFE) combining excellent chemical stability and thermoplastic processability. Although the properties of THV may be modified by crystallization, little is known on how crystallization is influenced by the chain microstructure of THV. We analyzed the chain microstructure of THV‐221G by solid‐state 19F NMR spectroscopy under fast magic angle spinning, revealing that THV‐221G contains 43.8 mol % TFE, 46.0 mol % VDF, and 10.2 mol % HFP. Sequence analysis revealed that the TFE units are preferentially located next to other TFE units. The HFP units, which are obstacles to crystallization because of their bulky CF3 side groups, are preferentially located next to VDF units. WAXS measurements correspondingly revealed the presence of THV‐221G crystals with PTFE‐like packing and of further THV‐221G crystal populations with widened d‐spacings caused by the incorporation of certain amounts of HFP units into the THV‐221G crystals. Under confinement imposed by the cylindrical nanopores of self‐ordered alumina, the THV‐221G melting point decreased with decreasing pore diameter. Although direct impingement of the growing THV‐221G crystals on the pore walls is unlikely, the geometric confinement limits the access of growing THV‐221G crystals to crystallizable THV‐221G chain segments. © 2019 Wiley Periodicals, Inc.

“…Similarly, alkyne-terminated poly(lactic acid) (PLLA) and PVDF (N3-PVDF-N3) homopolymers "clicked" together to obtain double crystalline PLLA-b-PVDF-b-PLLA triblock copolymers [47]. The same strategy was applied for the synthesis of well-defined poly(3-hexyl thiophene)-b-PVDF-b-poly(3-hexyl thiophene) copolymers [16,48,164].…”

This review highlights the synthesis, properties and applications, as well as the potential, of poly(vinylidene fluoride) (PVDF)-based complex macromolecular architectures (CMAs), a class of materials that has not received much attention in the literature. PVDF, the second in production fluoropolymer, is an attractive material due to its outstanding properties (high thermal stability and chemical inertness) along with its piezo-, pyro-and ferro-electrical performance. Even though only a small number of reports on PVDF-based CMAs have been published, growing interest in the synthesis/properties of non-linear structures (graft, miktoarm star, star and dendrimers) has emerged due to their potential for application in areas such as drug/gene delivery, electronics and energy harvesting devices. The aim of this review is to present primary strategies for the synthesis of PVDF-based polymer materials with CMAs and critically discuss strategies and opportunities that may facilitate their commercialization. It can be anticipated that PVDF-based CMA polymers will play a progressively important role in materials science and nanotechnology, both in academia and industry.
