A synchronously chemically closed-loop and high-performance approach for furan-based copolyesters with robustness, high gas barriers, and high puncture resistance

Abstract

Utilizing bio-based resources is an essential part of the sustainable development of plastics. Meanwhile, the end-of-life options of this bio-based plastic must be considered to avoid contributing to the accumulation...

Hollow Microporous Organic Polymer@Hypercrosslinked Polymer Catalysts Bearing N-Heterocyclic Carbene–Iron Species for the Synthesis of Biomass-Derived Polymer Platforms

“…On the other hand, while catalytic systems for the transesterification of biomass-derived furan esters with diols have been reported, polyesters were obtained through successive polymeric condensation. − Thus, catalytic systems to produce polymer platforms, furan diols, are rare in the literature . In this regard, the catalytic system of this work supplies a new entry of Fe-based heterogeneous catalysts for the production of furan diol polymer platforms through biomass conversion.…”

Hytrel-like Copolymers Based on Furan Polyester: The Effect of Poly(Butylene Furanoate) Segment on Microstructure and Mechanical/Elastic Performance

“…This aims to protect the natural environment against overexploitation of fossil deposits, reduce energy consumption and greenhouse gas emissions during the production of both plant-derived monomers and polymers, as well as to achieve more efficient use of by-products in agricultural production. The investigations of the recycling of furan polyesters as well as their use in a closed loop are also very promising and beneficial for the natural environment [ 22 , 23 ]. Extensive research on furan polyesters reveals many similarities to terephthalate acid-based polyesters.…”

Fire-Safe Fully Bio-Based Schiff Base Epoxy Thermosets with Excellent Mechanical Properties and Adjustable Degradability

“…5,6 Therefore, more and more researchers have started to use biomass resources for their research. 7−9 So far, biomass raw materials like vegetable oils, 10,11 cardanol, 12,13 furans, 14,15 itaconic acid, 16,17 eugenol, 18,19 vanillin, 20,21 and isoflavones 22,23 have been used in the preparation of epoxy resins.…”

“…At present, most epoxy resins used worldwide are bisphenol A diglycidyl ether epoxy resin (DGEBA), which is prepared by reacting bisphenol A (BPA) with epichlorohydrin (ECH) . However, there are two constraints to the development of traditional petroleum-based epoxy resins: First, with the rapid depletion of resources, environmental pollution and resource shortage have become important issues, while the raw materials of traditional epoxy resins are all from fossil resources, and their large use is not conducive to environmental protection and sustainable development. , Second, numerous studies have shown that BPA, one of the main ingredients of DGEBA, may have adverse effects on human health because it may act as an androgen receptor antagonist. , Therefore, more and more researchers have started to use biomass resources for their research. − So far, biomass raw materials like vegetable oils, , cardanol, , furans, , itaconic acid, , eugenol, , vanillin, , and isoflavones , have been used in the preparation of epoxy resins.…”
