Whether it is in the textiles, paints and coatings, energy sector, polymers, plastics, woods, sugar chemistry, pharmacy, aerospace and the automotive industries, the multiplicity of applications of furans and their derivatives, have made steady, impressive, and progressive impacts over the last 9 decades. After World War II, due to the shift in focus towards the petroleum-based chemical feedstocks, research, and development studies of these impressive class of lignocellulosic-derived chemicals, slowed down markedly. The trend, however, has reversed remarkably in recent time, due to the pursuit for "green" and sustainable chemical feedstocks, coupled with the increasing concerns over climate change, volatile oil prices and the attendant undesirable environmental issues, associated with fossil hydrocarbons. Chemicals obtained from "green" inedible lignocellulosic biomass, such as: the furans and their derivatives, ranks amongst the most promising, sustainable, and industrially applicable alternatives to various petroleum-derived chemicals; further offering an enormous assortment of unique compounds/materials, and properties analogous to and even exceeding those derived from fossil hydrocarbons. This article reviews selected progresses, so far made, in the field of furans and its derivatives and their application portfolios; while recognising the immense contributions of Peters and Dunlop, who in no small measures, advanced the furan chemical industry during their research efforts at the Oat Hull Research Centre at the Quaker Oats Company, Cedar Rapids, USA.

“…[14] FDCA is an important building block for renewable biodegradable polymers and has been used in the packaging industry [15] to replace PET and also in flexible polymer films for optoelectronics. [16] Aliphatic C-4 diacids such as succinic and malic acid are important platform chemicals and a gateway to several high value intermediates used in the pharmaceutical and chemical industry. Due to the renewable nature and non-toxicity of these compounds they have found use as high-value monomers providing unique functional properties for next generation materials.…”

Scheme 7. Kinetic resolution of aromatic mandelic acid derivatives. Enantioselective hydrolysis of α-hydroxynitriles using nitrilases offer a facile approach to chiral hydroxy acids with theoretical yields of 100% in a dynamic kinetic resolution (DKR) process. Robertson et. al. identified 137 nitrilases after screening 651 environmental samples of which 44 were found to be (R) and 4 were (S)-selective on mandelonitrile. [36] Further investigation revealed nitrilase I and II to be proficient in the DKR of arylnitriles (rac-14 and 15) towards the synthesis of a panel of mandelic acid (R)-14 and phenyllactic acid derivatives (S)-15.[37] Scheme 8.Chemo-enzymatic DKR of α-hydroxynitriles towards the production of aromatic hydroxy acids. Dehydrogenases provide an alternative route to hydroxy acids via the asymmetric reduction of the pro-chiral ketone in α-keto esters. Fusion proteins consisting of glutathione Stransferase N-terminally linked to putative dehydrogenases from S. cerevisiae (Ypr1p and Gre1p) were used to reduce ethyl 2-oxo-4-phenylbutanoate to the corresponding alcohol with high enaniopurity.[38] Further systematic investigation by the same group on 18 reductases fused with GST showed activity towards α-and β-keto esters. [39] Five enzymes encoded from the yeast gene YDLI24w, YAL060w, YGL157w, YDR541c and YGL151w displayed excellent enantioselectivity across all three α-keto esters, affording the corresponding alcohol in >99% ee. Xu and co-workers engineered a highly stereoselective D-lactate dehydrogenase (D-LDH) towards a panel of aliphatic and aromatic αketoesters.[40] The Y52L mutant of D-LDH showed enhanced activity compared to the wildtype across the whole substrate panel (scheme 9). Scheme 9. Panel of α-keto acids using engineered D-lactate dehydrogenase (D-LDH). Values in brackets show % change in specific activity between wt and Y52L mutant.

“…Despite the interest in FDCA-based polyesters, there is a limited amount of information on the development of furan-based nanocomposites. The existing studies mainly focus on the addition of carbon-based nanofillers and nanoclays in PEF [ 15 , 26 , 27 , 28 , 29 , 30 ], but some research also deals with PBF [ 31 ], poly(propylene furanoate) (PPF) [ 32 , 33 ], or poly(hexamethylene furanoate) (PHF) [ 22 ], mainly prepared by in-situ polymerization in presence of a nanofiller suspension. In these cases, nanofillers are added to increase the mechanical properties but especially the crystallization kinetics and the gas barrier performance [ 22 ].…”

Mechanical and Functional Properties of Novel Biobased Poly(decylene-2,5-furanoate)/Carbon Nanotubes Nanocomposite Films

The present work investigates the microstructural, thermo-mechanical, and electrical properties of a promising, but still not thoroughly studied, biobased polymer, i.e., poly(decylene furanoate) (PDeF), and its performance when multi-walled carbon nanotubes (CNTs) are added. After sample preparation by solution mixing and film casting, the microstructural investigation evidences that the fracture surface becomes smoother and more homogeneous with a small fraction of CNTs, and that the production process is suitable to achieve good disentanglement and dispersion of CNTs within the matrix, although some aggregates are still observable. CNTs act as nucleating agents for PDeF crystals, as evidenced by differential scanning calorimetry, as the crystallinity degree increases from 43.2% of neat PDeF to 55.0% with a CNT content of 2 phr, while the crystallization temperature increases from 68.4 °C of PDeF to 91.7 °C of PDeF-CNT-2. A similar trend in crystallinity is confirmed by X-ray diffraction, after detailed Rietveld analysis with a three-phase model. CNTs also remarkably improve the mechanical performance of the bioderived polymer, as the elastic modulus increases up to 123% and the stress at break up to 131%. The strain at break also increases by +71% when a small amount of 0.25 phr of CNTs are added, which is probably the consequence of a more homogeneous microstructure. The long-term mechanical performance is also improved upon CNT addition, as the creep compliance decreases considerably, which was observed for both the elastic and the viscoelastic component. Finally, the films become electrically dissipative for a CNT content of 1 phr and conductive for a CNT amount of 2 phr. This study contributes to highlight the properties of bioderived furan-based polymer PDeF and evidences the potential of CNTs as a promising nanofiller for this matrix.
