Partially Bio-based Colorless and Transparent Poly(amide-imide)s Derived from 2,5-Furandicarboxylic Acid

Recent advances in the development of green furan ring-containing polymeric materials based on renewable plant biomass

“…Copolycondensation of FDCA and TPA chloroanhydrides with prepolymerized fluorinated diamino-polyamide, followed by the treatment of materials with acetic anhydride, results in partially biobased block copoly(amide-imide)s suitable for colorless transparent film casting. 161 Poly(ester-amide) analogues of poly(propylene furanoate), synthesized from FDCA, PG and 1,3-diaminopropane, exhibit good mechanical properties and high thermal/thermo-oxidative stability. 162 Copolymerization of FDCA with diols and diamidodiols results in poly(ester-amide)s with rapid crystallization and increased crystallinity compared to analogous polyesters due to the suppression of intramolecular hydrogen bonds by the alkylene spacer (Fig.…”

High-Performance Polyimides Derived from Biomass: Design, Synthesis, and Properties

“…Polyimides (PIs) are inescapable and irreplaceable raw materials in engineering plastics, aerospace, and military fields owing to their confluence in heat resistance, − good electrical conductivity, ,, and strong mechanical properties. ,− However, the traditional PIs are derived from fossil-based raw materials, which not only bring environmental pollution during the refining process but also speed up fossil fuel depletion. , Sustainable material concepts emphasize reduced fossil-based polymer dependence. − Selective transformations of biomass to create PIs provide a promising alternative since biogenic feedstocks use solar energy and CO 2 to produce compounds . In addition, the carcinogenicity of petroleum-derived diamines have posed health challenges for users and sparked widespread controversy. − Currently, bio-based PIs have been limited to the addition of bio-based content, which is far from the early goals of revolutionary replacement. − This limitation is mainly attributed to the design contradiction between bio-based sources and polymer properties.…”

“…The general synthesis process for PIs is the polycondensation of dianhydride and diamine, in which the performance of PIs is determined by the structure of chosen monomers. , Therefore, rational design of bioderived monomers before polymerization could yield the specific green PIs. − Evidence of research results demonstrated that the introduction of aliphatic chains or the trifluoromethyl group (−CF 3 ) contributes to the transmittance of PIs. For instance, PIs prepared from modified monomers such as sorbitol, 4-aminocinnamic acid, and inositol show good performance in terms of transmittance. ,,, Additionally, some researchers disclosed that using monomers containing a benzene ring provide superior thermal stability, such as lignin-based and adenine-based PIs. ,, More recently, the designed monomers containing hydrogen bonding bring additional benefits in PIs, ,,, which with a bio-based content of 17.6% of modified furan-2,5-dicarboxylic acid showed excellent balance in superior physiochemical properties .…”

Preparation of poly(melamine‐formaldehyde‐2,2′‐bis(trifluoromethyl)benzidine) high‐performance fibers

“…Xu et al 18 introduced TFMB into the polymer structure through copolymerization modification, which effectively improved the heat resistance of polyisoimide, as well as the ablation protection properties of the composites. Jang et al 19 prepared poly (amide‐imide) s (CPAIs) with an increase in the proportion of TFMB‐containing segments, and the mechanical properties of the materials improved. Therefore, the TFMB structure is introduced between the MF molecular chains, which is expected to improve the mechanical properties of fibers.…”
