Poly(vinylidene fluoride) (PVDF) is a representative piezoelectric material, and is used in many applications such as energy storage and sensor. These piezoelectric materials can be blended or chemically bonded with light emitting materials to produce the synchronized piezoelectric-luminescent (SPL) materials. In this study, we developed the SPL material by graft copolymerization of PVDF and polyfluorene-based polymer. P(F6OH-F8-TBT), a red-light emitting polymer, was synthesized via Suzuki polycondensation. For graft copolymerization with PVDF, Macro chain transfer agent (Macro CTA) was fabricated by esterification between the hydroxyl group of P(F6OH-F8-TBT) and xanthate. Finally, P(F6OH-F8-TBT)-g-PVDF with the PVDF chain as a side chain was synthesized through radical addition fragmentation transfer (RAFT) polymerization. The synthesized polymers were characterized for structure, and luminescence and piezoelectric performances were evaluated by fabricating the device. |
