摘要
为揭示颗粒光散射与文物字迹淡化作用的关联性,利用具有负电性的脱质子化聚丙烯酸(PAA)与带正电的TiO_2颗粒间的静电相互作用,可获得有色纸张负载颗粒物的模型样,分别考察了模拟样中颗粒间隙在不同折光率介质下的微观结构及反射光谱。结果表明:纸张表面负载TiO_2颗粒后光散射程度增大,纸张颜色变浅;当利用较高折光率离子液体填充颗粒孔隙时,淡化的颜色在一定程度上得到了恢复。利用上述原理对一例淡化字迹的唐代经文进行了显现,取得了良好效果。
To reveal the relationship between scattering derived particles and faded handwriting, the colored paper loaded particles as simulation sample was prepared by electrostatic interaction between negatively charged poly (acrylic acid) on paper and positively charged TiO2 particles in solution. The microstructures and reflectance spectra in different refractive media of modeled paper were investigated, respectively. The results showed that after loaded TiO2 particles, the paper possesses higher scattering intensity and light color, while, the paper was introduced a high refractive index ionic liquid, the faded color could be recovered. Using above principle, a faded buddhish text was developed successfully. This research result is very useful in developing of faded colored drawing.
