“…The SIC formation behaviour of PEF has received attention in the last decade in the scientific literature. Not only the crystalline structure of SIC [ 129 , 130 , 131 , 137 ], but also the formation of SIC and the influence of stretching conditions, differ from that of PET [ 132 , 138 , 139 , 140 ]. This difference is mainly attributed to the lower entanglement density of PEF [ 128 ], meaning that PEF needs to be stretched more before a similar amount of orientation is built up.…”

The Road to Bring FDCA and PEF to the Market

Biobased polymers and materials are desperately needed to replace fossil-based materials in the world’s transition to a more sustainable lifestyle. In this article, Avantium describes the path from invention towards commercialization of their YXY® plants-to-plastics Technology, which catalytically converts plant-based sugars into FDCA—the chemical building block for PEF (polyethylene furanoate). PEF is a plant-based, highly recyclable plastic, with superior performance properties compared to today’s widely used petroleum-based packaging materials. The myriad of topics that must be addressed in the process of bringing a new monomer and polymer to market are discussed, including process development and application development, regulatory requirements, IP protection, commercial partnerships, by-product valorisation, life cycle assessment (LCA), recyclability and circular economy fit, and end-of-life. Advice is provided for others considering embarking on a similar journey, as well as an outlook on the next, exciting steps towards large-scale production of FDCA and PEF at Avantium’s Flagship Plant and beyond.

“…As it can be seen, the as-received PHV appeared amorphous. However, the annealed, at multiple temperatures, as well as the strain-induced sample exhibited the same XRD pattern as the initial material, without a signal of strain hardening as in the case of PEF and PET. − In contrast with PHV, its homologues poly(hexamethylene terephthalate) (PHT) and poly(hexamethylene 2,5-furan dicarboxylate) (PHF) are semicrystalline materials with fast crystallization rates. − Furthermore, in contrast with PHT and PHF, PHV has a methoxy substituent on its repeating unit and an ether bond in place of the −COO which seem to negatively affect chain folding of the otherwise flexible methylene sequence. Methoxy group substituents also affect the conformational regularity and chain packing ability of poly(ethylene syringate) …”

The negative environmental effects of conventional polymeric materials have intensified the research toward the production of biobased counterparts. Vanillic acid (VA), a vanillin oxidation product, is a relatively new and most promising aromatic monomer for the synthesis of biobased polyesters. In this work, the synthesis of a new, high molecular weight alipharomatic polyester, poly(hexylene vanillate) (PHV), using 4-(6-hydroxyethoxy)-3-methoxybenzoic acid via a two-stage melt polycondensation method is reported. The success of the polymerization was confirmed using nuclear magnetic resonance spectroscopy (NMR) and Fourier-transformed infrared spectroscopy (FTIR), while the number-average molecular weight (Mn) was estimated by size-exclusion chromatography (SEC). Moreover, the thermal behavior of PHV was determined with differential scanning calorimetry (DSC), and insights on the thermal stability and degradation mechanism of PHV were given. The mechanical and thermomechanical properties of the synthesized material were investigated, revealing a thermoplastic elastomer behavior, with elastic recovery at room temperature, associated with the formation of a mesophase status. Finally, rheological tests were applied, indicating that PHV is easily processable and fully recoverable upon yielding and flow cessation.

“…Accordingly, it is essential to optimize main process conditions in the roll-to-roll manufacturing system. However, excessive deformation may occur in the material due to changes in the elastic modulus and coefficient of thermal expansion that are caused when the web is heated to a high temperature in the drying section [ 49 , 50 ].…”

Web Wrinkle Defects due to Temperature Profile in Roll-to-Roll Manufacturing Systems

The roll-to-roll manufacturing system is extensively used for mass producing products made of plastic, paper, and fabric in several traditional industries. When flexible substrates, also known as webs, are heated and transported inside the dryer, an inconsistent temperature distribution occurs on the material in the machine direction (MD) and cross-machine direction (CMD). If rollers are not aligned in parallel on the same plane in the roll-to-roll web handling process, or if roller misalignment exists, strain deviation occurs in the web, resulting in lateral displacement and web wrinkles. Therefore, this study examined a wrinkle, which is a thermal deformation that occurs when an inconsistent web temperature distribution is formed on the material inside a dryer. The changes in the elastic modulus and thermal expansion of the web were also examined. Experiments were conducted using a PET film, and its elastic modulus and thermal expansion were examined. The results showed that the presence of a web wrinkle defect can cause a thickness deviation in the functional layer manufactured on the web. Moreover, an appropriate operating speed should be set to reduce the CMD temperature deviation, thereby reducing instances of wrinkle defects.
