摘要

Polymeric materials incorporating renewable vegetable oils have made significant advancements, primarily due to their ability to greatly reduce our reliance on petroleum-based oils, which can be potentially harmful when used as plasticizers in both industrial and biological sector. Herein, we intend to develop a novel class of polymers derived from renewable olive oil as a sustainable alternative to petroleum-based polymers. Using the thiolene photoclick reaction, polyurethane was synthesized by mixing polyol with two distinct diisocyanates, namely toluene diisocyanate (TDI) and methylenediphenyl diisocyanate (MDI), to produce OLPU I and OLPU II. Extensive analysis through FT-IR confirms the bio-derived nature of the resulting polyurethane polymer. Furthermore, this biodegradable polymer exhibits impressive mechanical properties, balancing rigidity and ductility effectively. In comparison to OLPU I, OLPUII shows high tensile strength of about 8.6 Mpa. Notably, this bio-derived polymer demonstrates exceptional antimicrobial activity, surpassing the performance of synthetic polymers. In comparison to OLPUI, the OLPU II has superior anti-inflammatory activity of 75 ± 4% and the highest antioxidant activity of 88.71 ± 2%. Additionally, the reinforced polyurethane showcases outstanding thermal, mechanical, and antimicrobial characteristics. This makes it a promising solution for addressing environmental sustainability concerns by replacing synthetic polymers in various applications.
