Nano - crystalline titanium dioxide (TiO(2)) in rutile
crystal form, generally used to indicate particles less than 100 nm in diameter, is mainly
applied as pigment, adsorbent and UV absorber. The incorporation of a nano-sized titanium dioxide
powder into a liquid media is made by dispersion process, that the final product consists of fine
particles distribution throught the medium. So it is regarded as necessary for us to investigate
in detail the factors which may have important effect upon the homogenious distribution of TiO(2)
nanoparticles in clearcoat as liquid media. In this work, titanium dioxide nano-powders were
prepared by the co-precipitation method. Using various techniques, including transmission
electron microscopy (TEM) and X-ray diffraction (XRD), obtained powders were studied in order to
find the possible elements of affecting the microstructures and grain size. The aim of this study
is to determine the photostabilisation efficiency of TiO(2) in a clear coat as UV absorber
considering the preparation of stable dispersions by using different surfactants and percentage
of TiO(2).
