聚苯乙烯荧光乳液的制备及其性能研究
Preparation of Polystyrene Fluorescent Emulsion and Its Properties
摘要
Abstract
In order to improve the water solubility of naphthalimide and the combination with the paper, the polystyrene fluorescent emulsion was prepared by emulsion polymerization,and its synthesis condi-tions were optimized. The structure was determined by FT-IR and gel permeation chromatography (GPC). The optical properties were measured by UV and fluorescence spectra. Its morphology was ob-served by scanning electron microscopy and transmission electron microscopy. The fluorescence quantum yield is 78.57%. After polymer coats on the surface of the paper, its initial whiteness increases by 8.19%(ISO). After 48 h UV light irradiation, compared with that of the blank paper and the paper which coats the micromolecule fluorescent whitening agent,the whiteness of the paper which coats the polymer decreases by 3.68%(ISO) and 3.16%(ISO),respectively. The results show that the prepared polymer emulsion and paper adhesion are good,with whitening and yellowing inhibition.关键词
