The need for renewable alternatives to petroleum-based polymers is growing in response environmental concerns and resource depletion. Polyimides (PIs), which are traditionally synthesized from petroleum-derived monomers, raise sustainability issues. In this work, 2,5-furandicarboxylic acid (FDCA) was employed as a sustainable feedstock synthesize bio-based diamine monomer, N,N'-bis(4-aminophenyl)furan-2,5-dicarboxamide (FPA). Subsequently, FPA polymerized with various aromatic dianhydrides through thermal imidization, yielding four distinct polyimide (FPA-PI) films. resulting films exhibited exceptional stability, 5% weight loss temperatures exceeding 425 °C char yields ranging 54% 60%. Mechanical characterization revealed high elastic moduli (2.14-3.20 GPa), moderate tensile strengths (50-99 MPa), favorable aging resistance. Gas permeation tests demonstrated promising CO2/N2 separation performance, FPA-DODDA achieving superior selectivity (27.721) compared commercial such Matrimid®, polysulfone, polycarbonate, while FPA-BPFLDA enhanced CO2 permeability (P(CO2) = 2.526 Barrer), surpassing that of Torlon®. performance these FPA-PI governed synergistically by size-sieving effects solution-diffusion mechanisms. This work not only introduces novel synthetic route but also highlights the potential replacing conventional materials high-temperature gas applications, thereby advancing sustainability.
