| Abstract: | Nanometer zinc oxide was prepared by solid phase reaction. And the ultraviolet visible spectral properties of nanometer zinc oxide colloidal solution dispersed in both water and oil phases were studied. The results show that the absorbance of the colloidal solution to ultraviolet light increases with the decrease of wavelength and reaches about 2.5 at the wavelength of 200 nm. When the mass fraction of nanometer zinc oxide becomes lower, the transmittance of the colloidal solution to visible light gets higher, and it is much higher than that of normal zinc oxide under the same conditions, indicating that nanometer zinc oxide dispersed in both water and oil phases has high transmittance to visible light and good shield to ultraviolet light. Therefore it is suitable for the replacement of organic ultraviolet absorber and titanium dioxide in cosmetics. |
