Abstract:
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.
KeyWords:
