The color filter with the red, green and blue pigment derived from mill-base processing is known as essential components of the liquid crystal display (LCD). Among these, the color properties of Cu-Phthalocyanine(Cu-Pc) mainly have used as blue pigment. Particularly, the particle size and distribution have played an important role in the performance of color filter. In this study, we fabricated Cu-Pc/modified SiO2 core-shell composite particles to enhance dispersion and storage stability in organic solvent. The surface of Cu-Pc was coated with SiO2 by hydrolysis of Na2SiO3. The obtained particles were then modified with 3-mercaptopropyltrimethoxysilane to form composite particles containing thiol groups. After surface modification of composite particles, 3 different type of copolymers designed as a role of the binders were grafted onto the surface of composite particles via radical polymerization by thiolene reaction. |
