Description

We prepared nanocomposite films containing the nanodiamond, which has excellent water-dispersibiliy and high refractive index (2.42). In this study, a water-soluble poly(vinyl alcohol) was used as a matrix. The dispersion state of nanodiamond in a poly(vinyl alcohol) matrix was observed using atomic force microscope (AFM), and the optical properties were investigated. AFM images showed that the nanodiamonds were highly dispersed without recognizable aggregation in the polymer matrix. The resulting nanocomposite film was transparent, and the light scattering was definitely observed. Although the nanodiamond was mainly used in applications based on its mechanical property, this material could also offer the potential applications in optical materials such as transparent screen.
