Abstract

Polymer photo-oxidation aging is a significant issue in plastics engineering, leading to reduced performance, shorter lifespan, and additional pollution. Anti-aging agents, including antioxidants and ultraviolet (UV)-shielding agents, are used to ameliorate the above problems. However, multi-component agents involve complex synthesis, mixed processing, and environmental concerns. Therefore, developing robust, multi-functional, one-component anti-aging agents is crucial. This study proposed a new class of one-component poly(coumarin) anti-aging agents, synthesized through enzymatic polymerization of coumarin. These agents exhibited a broader UV absorption spectrum and higher antioxidative capacity than commercial UV-shielding agent UV326 and antioxidant AO1010. Calculating the O-H bond dissociation energy and reaction energy barrier with peroxy free radicals (ROO˙) showed that the material could effectively attenuate UV radiation and scavenge free radicals, improving anti-aging properties. Further studies indicated the potential of poly(coumarin) anti-aging agents for enhanced polymer photostability and improved food preservation packaging. Consequently, poly(coumarin) nanoparticles can act as versatile anti-aging compounds, potentially replacing conventional multi-component agents and providing a new foundation for one-component materials with multiple functions.

期刊介绍： Materials Horizons is a leading journal in materials science that focuses on publishing exceptionally high-quality and innovative research. The journal prioritizes original research that introduces new concepts or ways of thinking, rather than solely reporting technological advancements. However, groundbreaking articles featuring record-breaking material performance may also be published. To be considered for publication, the work must be of significant interest to our community-spanning readership. Starting from 2021, all articles published in Materials Horizons will be indexed in MEDLINE©. The journal publishes various types of articles, including Communications, Reviews, Opinion pieces, Focus articles, and Comments. It serves as a core journal for researchers from academia, government, and industry across all areas of materials research. Materials Horizons is a Transformative Journal and compliant with Plan S. It has an impact factor of 13.3 and is indexed in MEDLINE.
