2025年1月1日 · Key challenges in synthesizing 2,5-furandicarboxylic acid (FDCA), the monomer for PEF, are highlighted, particularly the difficulty in achieving high yield and purity, which limits large-scale production. The review also evaluates the thermo-mechanical properties of PEF, showing its potential for use in demanding engineering applications.

2021年6月1日 · The two monomers used to synthesize a 100% bio-based PEF, namely 2,5- furan dicarboxylic acid (2,5-FDCA) and mono ethylene glycol (MEG), are synthesized simultaneously from a novel electrochemical reactor using bio-based raw materials.

2018年4月27日 · A thorough vibrational spectroscopy and molecular modeling study on poly(ethylene 2,5-furandicarboxylate) (PEF) explores its conformational preferences, in the amorphous and crystalline regions, wh...

Polyethylene 2,5-furandicarboxylate, or PEF for short, is a novel polymer with a chemical structure that has a high resemblance to that of PET. It is produced by polycondensation of the monomers FDCA (2,5-furandicarboxylic acid) and MEG (mono-ethylene glycol), analogous to the polycondensation of the raw materials used to produce PET.

2018年7月11日 · PEF，全称是polyethylene furanoate (PEF)，严格说英文全称是Polyethylene 2,5-furandicarboxylate，中文全称是聚2，5－呋喃二甲酸乙二醇酯，即下图所示的聚合物： 合成PEF材料所需要的原料可以是来自生物质原料，…

2021年2月23日 · We report on the pilot scale synthesis and melt spinning of poly(ethylene furanoate) (PEF), a promising bio-based fiber polymer that can heave mechanical properties in the range of commercial poly(ethylene terephthalate) (PET) fibers.

2022年2月21日 · (furandicarboxylic acid), the building block of PEF (polyethylene furanoate): a plant-based, fully recyclable plastic material with superior performance. FDCA is polymerised with plant-based mono-ethylene glycol (MEG) to make a 100% plant-based PEF polymer. Avantium has successfully demonstrated this YXY® Technology in its pilot

2020年7月30日 · For PEF polymerization, they discovered that C n MIM-based ILs with stronger electronegativity and proton-donating ability are more efficient catalysts. PEF with the highest molecular weight (M n ¯ = 52.5 kg mol −1) was obtained using [C 2 MIM]BF 4 as an efficient, selective, and eco-friendly catalyst.

2023年6月16日 · Poly (ethylene furanoate) (PEF) is a promising bio-based polyester synthesized from FDCA, or its derivate DMFD, and ethylene glycol (EG) with a superior barrier and thermal and mechanical properties to those of PET. The 100% renewable PEF offers a promising alternative to fossil-based commodity plastics in food packaging, such as bottles and films.

2024年10月30日 · PEF is a potential biobased replacement of widely used poly (ethylene terephthalate) (PET), especially since it offers improved mechanical and gas barrier properties compared to PET and other petrol-based terephthalate homologs. Moreover, PEF is recyclable using technology developed for PET.
