Abstract
|
Biobased nanoparticles hold promise for polymer stabilization due to their renewable and eco-friendly properties; however, improving their anti-aging efficiency remains challenging due to the complexity of tuning their structure. This work synthesizes mesoporous polydopamine nanoparticles (MPDA) through a simple supramolecular assembly process using templates to form a highly ordered mesoporous structure. The potential of MPDA as a sustainable and efficient alternative for polymer stabilization was explored. In comparison with solid polydopamine nanoparticles (NPDA), MPDA exhibits a 111% increase in oxidation induction time and a 9 oC higher initial degradation temperature (T5%) in thermogravimetric analysis, demonstrating its superior performance in enhancing polymer stability. MPDA’s unique mesoporous structure provides an improved specific surface area, which not only boosts its antioxidant performance but also significantly enhances its ability to chelate metal ions, thereby improving the oxidative and thermal stability of polymers. The findings not only provide new insights into the design of advanced stabilizers but also highlight the potential of MPDA in enhancing the durability and recyclability of materials for a wide range of applications.
