壳聚糖基聚合物点荧光材料的合成及其对纸张的抗紫外老化性能
Synthesis of Chitosan-based Polymer Carbon Dots Fluorescent Materials and Their UV Aging Resistance Properties for Paper
摘要
Abstract
Fluorescent materials P( CS-g-CA) Ds were prepared by hydrothermal method using chi-tosan, citric acid, and N-(2-hydroxyethyl) ethylenediamine as raw materials. It was found that graf-ted citric acid could significantly increase the quantum yield of chitosan polymer carbon dots. The P( CS-g-CA) Ds were characterized by infrared spectroscopy, ultraviolet spectroscopy ( UV) , X-ray powder diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy, thermal de-composition and photoluminescence spectra. The fluorescence performance tests at different pH val-ues show that P( CS-g-CA) Ds have excellent stability in the pH range of 4 -12. The application performance of P( CS-g-CA) Ds in rice paper was studied by testing the carbonyl index and the vinyl index of the paper before and after UV aging. The results demonstrate that P(CS-g-CA)Ds have good UV aging resistance performance.关键词
