Study on the optical properties of acrylic-modified silica nanocomposite coatings prepared via miniemulsion polymerization

Encapsulation of modified silica nanoparticles was carried out by means of miniemulsion polymerization.The modification of silica nanoparticles was conducted via an extremely efficient method. Miniemulsion polymerization of acrylic monomers in the presence of modified silica nanoparticles results encapsulated silica nanoparticles. Different samples with various amounts of modified silica content were prepared. The optical properties of the dried films of the prepared nanocomposite latexes were evaluated and results indicated that the resulting nanocomposite coatings have high transparency in visible region, while they show opacity in UV region. Also, according to the AFM images and gloss measurement results, it was found that modification process could efficiently improve dispersion of silica nanoparticles in polymer matrix
