  Abstract

Due to the frequent occurrence of abnormal weather phenomena caused by environmental pollution, environmental regulations have been strengthened, increasing the demand for eco-friendly products that limit volatile organic compounds (VOCs) and biocarbon content. This study introduced bio-based polyols to manufacture waterborne polyurethane to address this issue. Waterborne polyurethanes are environmentally friendly resins that do not emit VOCs, as they replace organic solvents with water. This study developed bio-based self-healing waterborne polyurethane using 2-hydroxyethyl disulfide, incorporating disulfide bonds. The resulting polyurethane demonstrated good flexibility (glass transition temperature, Tg, -70.64 oC) and excellent thermal stability (5% weight loss at 280.34 oC). Furthermore, it exhibited eco-friendly characteristics with a biocarbon content of 39%, surpassing the bio-based carbon content regulation of 20-25%. When a crosslinker was applied, the polyurethane achieved a self-healing efficiency of 86.96% and maintained stable peel strength across various flexible substrates.
