| 中文摘要: |
| 通过乳液聚合法制备了荧光聚合物聚苯乙烯荧光乳液，对其合成条件进行了优化。通过红外光谱仪、凝胶渗透色谱仪确定其结构；利用紫外 可见分光光度计、荧光分光光度计测定其光学性能。将该荧光聚合物涂布于纸张表面后，通过测量接触角对比发现，经过处理的纸张表面接触角比空白纸张大20°，且初始白度提高了16.0 个百分点；在紫外老化箱中老化处理48 h后，涂有该荧光聚合物的纸张白度比空白纸张和涂有荧光单体的纸张分别少下降了8.79个百分点和8.08个百分点。 |
| Abstract: |
| Polystyrene fluorescent emulsion was prepared by emulsion polymerization,and its synthesis conditions were optimized. Its structure was determined by FT-IR and gel permeation chromatography(GPC).The optical properties were measured by UV and fluorescence spectra. The contact angle of the paper coated the emulsion was 20° larger than the blank paper, and its whiteness increased by 15.6%. After UV light irradiation for 48 h, compared with the blank paper and the paper coated with micromolecule fluorescent whitening agent, the whiteness reduction of the paper coated with the polymer decreased by 8.79 and 8.08 percentage points, respectively. |
