“…The cured polymer was also observed with a strain-hardening behavior due to the reorientation of polymer chains during stretching. Similarly, a difunctional monomer, DEFA, and a trifunctional monomer, TMFA, based on trans -3-(2-furyl)acrylic acid were photo-cross-linked to give polymers with good thermal oxidation stability (Scheme C) . The addition of a sensitizer in the system was found to significantly improve the double bond conversion and polymerization rate.…”

Light-induced cross-linking of liquid monomers has found widespread applications in various fields, such as dentistry, coatings, tissue engineering, and 3D printing. These processes typically rely on monomers derived from petrochemicals, which are volatile in price and are becoming increasingly depleted, compelling researchers to explore alternative sources from forestry and agricultural crops. The renewability of these resources makes them a promising option for developing substitutive materials with similar or superior properties. The various structural subunits in biomass offer alternative building blocks for petroleum-based photopolymers including the double bond-containing and hydrophobic fatty acids and terpenes, hydrophilic carbohydrates and proteins, aromatic furfural compounds from carbohydrates, and phenolic moieties in lignin. They can be transformed into photopolymers by the inherent or chemically introduced photocurable bonds. This review seeks to highlight recent advancements in transforming renewable platform chemicals into photocurable systems for photopolymerization processes and examines the thermomechanical properties and applications of the resulting cured materials. Furthermore, potential issues for improvement are also identified, such as the cost-effectiveness of biomass-based photopolymers and the risk in competition with food production. The perspectives on future directions for improving the renewability in this area are also given.
