Polyvinylidene fluoride (PVDF) polymers are known for their piezoelectric and pyroelectric properties. Such properties allow them to be used as functional materials for creation of flexible thin-film pressure and temperature sensors, as well as memory devices based on organic transistors and self-powered electronics. In addition, various copolymers based on polyvinylidene fluoride are often used to reduce the degree of crystallinity and lower the Curie temperature, which are able to combine unique properties with easy of processing. . The synthesis of double and ternary copolymers based on polyvinylidene fluoride with grafted chains of polyethyl methacrylate (PEMA) and polyacrylonitrile (PAN) was carried out by photoinduced reversible deactivation radical polymerization (RDRP). An important advantage of this method was the use of a minimal amount of the catalytic system and the ability to control the molecular weight characteristics of the graft copolymers by changing the amount of ligand and reaction time.
