Abstract
It is of great significance to enhance mechanical properties and thermal stability of high-performance polymers. A new coordination polymer film (Ni/PPy) with high tensile strength and excellent heat resistance has been successfully prepared via a palladium-catalyzed C-C coupling reaction. For newly synthesized polymer film, bipyridine is incorporated into polymer chains during the synthesis process and subsequently crosslinked by nickel acetate. More importantly, Ni-coordination can be removed by external pyrophosphate to recover the linear polymer, which endows the polymer with recyclability. This strategy is expected to be an effective means for increasing the mechanical properties and recyclability of high-performance polymer materials.
