Abstract
ABSTRACT In recent years, carbon quantum dots (CQDs) have been employed in the functionalization research of fiber-based materials due to their distinctive physicochemical properties. We used citric acid and urea as precursors and combined with hydrothermal method to prepare green and non-toxic carbon quantum dots (NCQDs), which were loaded into four-color twisted bamboo fiber bundles and possessed photoluminescence effect by simple impregnation method. Based on the verification of the structure and fluorescence properties of NCQDs, the fluorescent twisted bamboo fiber tows were comparatively analyzed for their chemical composition, microscopic morphology, mechanical properties, color difference, and thermal stability. The results showed that the four groups of fluorescent twisted bamboo fiber tows emitted uniform and bright blue fluorescent effects under UV light irradiation, and increased the tensile strength by 19.77% ~ 39.27% and the sexual modulus by 66.11% ~ 88.78% compared with the original twisted bamboo fiber tows. The impregnated carbon quantum dot solution enhances the functionality of the fiber bundle while enriching the color expression. It is expected to be a potential application material in the fields of smart marking, fluorescent anti-counterfeiting, interior decoration, and home textile industry.
