Furandicarboxylic acid is considered one of the most representative biomass matrix platforms and has been widely used to synthesize various novel biomaterials. In this study, a series of copolymerized poly (aryl ether ketone) resins with excellent properties have been prepared by combining the nonlinear structure of furan ketone with the weakly polarized cyclohexane structure. And the relationship between the structure and properties of the resins has been systematically studied. The results showed that the synthesized resins had excellent thermal properties, and the 5% thermal decomposition temperature could reach up to 478 °C. In addition, the resin exhibits good solubility and can be dissolved in the most common solvents. Its water absorption is deficient, at only 0.71%. At 10 GHz, the lowest dielectric constant of the resin is 3.05. Most importantly, using bio-based monomers in this study provides an environmentally friendly strategy for material design and synthesis, providing a green way to develop high-performance low-dielectric materials.
