“…A study of the TrFE RAFT polymerisation mechanism will be reported elsewhere. 22 The complete assignments of the chain-end signals for the PTrFE product made by RAFT was made possible by a set of 1D and 2D 1 H, 19 F and 13 C NMR experiments.…”

Well-defined fluoropolymers exhibit unique properties such as excellent oil and water repellency, satisfactory thermal stability, low refractive index, and low surface energy.The origin of these properties is attributed to the presence of strong electronegative and low polarizable Fluorine atom in the backbone of such polymers which leads to a strong C F bond (with a high bond dissociation energy of 485 kJ mol −1 ). Due to these features, these polymers have found applications as functional coatings, thermoplastics, biomedical items, separators and binders for Li-ion batteries, fuel cell membranes, piezoelectric devices, high quality wires and cables, etc. Usually, fluoropolymers are synthesized by conventional radical (co)polymerization of fluoroalkenes which leads to the production of (co)polymers with ill-defined end group, uncontrolled molar mass, and high dispersity values. In the last two decades, significant developments of various reversible deactivation radical polymerization (RDRP) techniques have helped the design of macromolecular architectures (including block, graft, star, dendrimers) on demand. However, for relevant new applications, well-defined fluoropolymers with well-defined macromolecular architectures (e.g. block copolymers as thermoplastic elastomers and electroactive polymers or graft copolymers for fuel cell membranes) are required.Several RDRP methods developed in the last couple of decades have paved the way for the synthesis of (co)polymers with well-defined molar mass, dispersity, chain end-functionality and

“…The SI-RAFT approach is of particular interest for the fluoropolymers as recent work showed that VDF as well as TrFE polymerisation could be controlled using xanthate agents. [44][45][46][47] Indeed, even if those monomers are prone to backwards additions, the RAFT polymerisation using O-Ethyl-S-(1methoxycarbonyl) ethyldithiocarbonate could afford an acceptable degree of control. In the present study, piezoelectric composites integrating barium titanate (BTO) nanoparticles incorporated into a P(VDFco-TrFE) copolymer matrix were prepared and their piezoelectric properties investigated.…”
