저온균일침전법으로 제조된 TiO2 분말의 아크릴레진에서의 분산특성 및 광분해 효과

Abstract

Dispersion stabilities and photocatalytic activities of rutile TiO2 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 TiO2 in the acrylic resin placed in the neutral region whereas that of TiO2 in the water placed in the acidic region, indicating that zeta potential and agglomeration of TiO2 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.
