Sustainable Bio-based Polyurethane Adhesives Utilizing PPG2000 and Renewable Polyols: Synthesis, Characterization, and Mechanical Properties

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: April 2, 2025

Developing high-performance, sustainable adhesives for automotive, aerospace, and industrial applications remains a major challenge due to the inherent trade-off between mechanical strength thermal stability in bio-based materials. While previous studies have explored polyurethane (PU) adhesives, achieving superior adhesion durability challenging when compared petroleum-based counterparts. This study presents novel adhesive system utilizing polypropylene glycol (PPG2000), isophorone diisocyanate (IPDI), renewable polyols (isosorbide-derived polyols, diglycerol, glycerol). The were synthesized via controlled one-shot polymerization process with 4-tert-butylphenol as an end-capping agent, enabling precise modulation of crosslink density molecular architecture. Fourier-transform infrared (FT-IR) spectroscopy confirmed complete urethane bond formation, isocyanate group (NCO%) titration validated stoichiometric conversion. Gel permeation chromatography (GPC) revealed distinct weight distributions, which influence performance by affecting density, elasticity, depending on polyol structure. Thermal analysis showed that isosorbide-derived formulations exhibited up 25°C higher degradation onset temperature 10°C increase glass transition (Tg) adhesives. Meanwhile, containing diglycerol glycerol demonstrated 39% shear (32.5 MPa) 77% improved impact resistance (36.8 relative reference system, attributed optimized segmental mobility crosslinking effects. work establishes strategic framework designing while acknowledging limitations such potential variability raw material sources suggesting future research into long-term environmental performance, not only surpasses conventional systems but also aligns principles green chemistry innovation. These findings offer pathway next-generation structural applications.

Conversion of Lignin to Nitrogenous Chemicals and Functional Materials

Materials, Journal Year: 2024, Volume and Issue: 17(20), P. 5110 - 5110

Published: Oct. 19, 2024

Lignin has long been regarded as waste, readily separated and discarded from the pulp paper industry. However, most abundant aromatic renewable biopolymer in nature, lignin can replace petroleum resources to prepare chemicals containing benzene rings. Therefore, high-value transformation of attracted interest both academia Nitrogen-containing compounds functionalized materials are a class that have wide applications chemistry, science, energy storage, other fields. Converting into nitrogenous is utilization pathway. Currently, there large amount literature exploring conversion lignin. comprehensive review lacking. The research progress functional reviewed this article. This article provides an overview chemical structure types industrial lignin, methods modification, well nitrogen-containing prepared various including their wastewater treatment, slow-release fertilizer, adhesive, coating, biomedical In addition, challenges limitations lignin-based encountered during development also discussed. It believed will act key reference inspiration for researchers biomass material field.
