Synthesis of Chitosan Polymer Dot Based Macromolecular UV Absorbers and Their Application in Natural Rubber
摘要
Abstract
Using chitosan as the raw material,chitosan-based polymer dots(PCSDs)fluorescent materials were synthesized via a microwave-assisted reaction.Subsequently,a novel macromolecular ultraviolet(UV)absorber,PCSDs-g-UV-0,was prepared by grafting the small-molecule UV absorber benzophenone(UV-0)onto the PCSDs under Mannich reaction conditions.The product was characterized to confirm its proposed structure.Finally,the application performance of the synthesized macromolecular UV absorber was evaluated by incorporating PCSDs-g-UV-0 into natural rubber and comparing its efficacy with that of the low-molecular-weight UV-0.The resistance to UV-induced aging was assessed by measuring the mass-loss ratio,carbonyl index,and vinyl index before and after accelerated aging.The results demonstrate that PCSDs-g-UV-0 imparts significantly superior anti-UV aging performance compared with UV-0.关键词
