Fluoropolymers: The Right Material for the Right Applications

Abstract

An overview on the synthesis, properties, and applications of fluoropolymers (PFs) is presented. First, a non-exhaustive summary on the homopolymers from conventional radical polymerization of fluoromonomers is proposed. FPs are interesting materials thanks to their outstanding properties such as thermal, oxidative and chemical resistances, low dissipation factor, refractive index, permittivity, and water absorptivity, as well as excellent durability and weatherability. Various strategies of synthesis are proposed, especially on recent studies on radical (co)polymerization of fluoroalkenes, just like their properties and applications ranging from coatings and energy-related materials (e.g. fuel cell membranes, components for lithium ion batteries, electroactive devices, and photovoltaics) to original fluorinated elastomers, surfactants, thermoplastic elastomers, thermostables, and optical devices.

Ligand Free Palladium‐Catalyzed Synthesis of α‐Trifluoromethylacrylic Acids and Related Acrylates by Three‐Component Reaction

“…More specifically, in a current ongoing research project, we have targeted the synthesis of α‐trifluoromethylacrylic acids and their use in subsequent transformations. In the literature, α‐trifluoromethylacrylic acids exhibited relevant applications in medicinal chemistry and materials science and have emerged as key intermediates for the production of valuable α‐trifluoromethyl asymmetric compounds as well as a high variety of polymers …”

“…In the literature, αtrifluoromethylacrylic acids exhibited relevant applications in medicinal chemistry [3] and materials science [4] and have emerged as key intermediates for the production of valuable α-trifluoromethyl asymmetric compounds [5] as well as a high variety of polymers. [6] As we recently reported the synthesis of alkyl αtrifluoromethylacrylates, [7] we first thought to simply hydrolyze the esters to the corresponding acids. Unfortunately, the various basic and acidic conditions which were tried were unsuccessful from the methyl αtrifluoromethylacrylate (Scheme 1, Eq.…”

Preparation and electroactive phase adjustment of Ag-doped poly(vinylidene fluoride) (PVDF) films

“…Poly(vinylidene uoride) (PVDF) is attractive because of its excellent pyro-, piezo-, and ferroelectricities. [18][19][20][21] Moreover, exibility, light weightness, easy processing, and presence of ve crystallite phases (a, b, g, d, and 3) [22][23][24][25] impart excellent mechanical properties, high thermal and chemical stabilities, and biocompatibility to PVDF. [26][27][28][29] The polar band g-forms are facilitate electrical applications.…”

An overview of the uses of per- and polyfluoroalkyl substances (PFAS)

“…45 In the energy sector, PFAS are known to be employed in solar collectors and photovoltaic cells, and in lithium-ion, vanadium redox, and zinc batteries. In addition, fluoropolymers are also used to coat the blades of wind mills 13 and PFAS can be employed in the continuous separation of carbon dioxide in flue gases (patent CN106914122 from 2017) 45 and as heat transfer fluids in organic Rankine engines. 48 These examples all show that the uses of PFAS are much more extensive than so far reported in the scientific literature.…”
