Summary: An alternative phosphorous soybean-oil-based polyol was used for flexible polyurethane foams synthesis, with the addition of 5% and 10% expandable graphite (EG) to improve flame retardancy. The combination of phosphorous polyols and EG showed significantly enhanced flame retardancy, with a three times increase in char yield, indicating a potential strategy for future flame retarded FPUFs.

Summary: In this study, novel soybean oil-based waterborne polyurethane coatings and films with significantly improved fracture toughness and flame retardancy were successfully synthesized using chain extenders BH and BDO. The mechanical properties of SPU films were effectively improved by the introduction of BH, showing remarkable enhancements in tensile strength, elongation at break, and fracture toughness. The flame retardancy of SPU films increased gradually with the BH molar content, reaching a high LOI value of 28.2% for SPU80 with 0.9 wt% phosphorus content.

Summary: In this study, the mechanical properties of vegetable oil-based waterborne polyurethane (WPUs) were improved by incorporating sustainable diols. The resulting films demonstrated higher tensile strength and toughness compared to state-of-the-art systems. Among the different diols investigated, WPU-B films exhibited superior performance and increased corrosion resistance. This research provides strategies for controlling the physical properties of environmentally friendly WPUs and developing high-performance coatings for anticorrosion applications.

Summary: This paper explores the use of environmentally friendly and renewable bio-based materials to prepare polyurethane. Epoxy soybean oil and polyethylene glycol were used to prepare soybean oil-based polyester polyols, which were then reacted with isophorone diisocyanate to synthesize soybean oil-based polyurethane. The properties of the polyurethane films were adjusted by changing the reaction conditions, and the results show that the properties of the polyurethane films change accordingly.

Summary: The depletion of natural resources and environmental concerns have led to the development of bio-based non-isocyanate polyurethane (NIPU) resins as sustainable substitutes for harmful isocyanates in the manufacturing of polyurethanes. This review provides a comprehensive analysis of the progress made in utilizing lignin and tannin to produce high-performance NIPU resins for wood adhesive applications. Studies have shown that NIPUs derived from lignin and tannin exhibit enhanced mechanical properties, decreased curing temperatures, and are devoid of isocyanates, making them promising alternatives for wood adhesives.
