- Dispersion stabilities and photocatalytic activities of rutile TiO_2 powders with unique nano-structure synthesized by homogeneous precipitation process at low temperature(HPPLT) have been investigated in the acrylic resin containing fluorostyrene in the range of 0~0.16 mole. Isoelectric point of TiO_2 in the acrylic resin placed in the neutral region whereas that of TiO_2 in the water placed in the acidic region, indicating that zeta potential and agglomeration of TiO_2 powder is strongly dependent on the pH and the type of solvent. To prepare an adhesion, an acrylic resin containing fluorostyrene was synthesized by a radical polymerization. The adhesion of coating layer was increased with increasing fluorostyrene's contents without changing the dispersion stabilities and degrading photocatalytic properties.
