Synthesis of Urethane Acrylate by Introducing Acrylic Groups to Enhance the Wear Resistance of Bio-Based Polyurethane

Bio-based polyurethanes (Bio-PUs) have attracted significant attention as eco-friendly alternatives to petroleum-based polymers. However, their industrial applications are often limited by poor mechanical durability, particularly insufficient wear resistance. To address this limitation, this study demonstrates a novel approach to enhance the abrasion resistance of Bio-PU by introducing acrylic groups to synthesize a high-performance urethane acrylate hybrid system.

Bio-PU prepolymers were chemically modified through functionalization with acrylic monomers, followed by a subsequent curing process to form a robust crosslinked network. The successful incorporation of acrylic groups and the chemical structure of the fabricated urethane acrylate were confirmed using Fourier-transform infrared spectroscopy (FT-IR). The effects of the acrylic content on the mechanical, thermal, and surface properties of the hybrid polymers were systematically investigated.
