Preparation of TiO2 Nanoparticles with Two Phases as additives into Local Paints
Aim of the research includes work to improve and modify local paints Specification (Modern Paints) by adding nanomaterials to the local paints. Titanium dioxide (TiO2 ) nanomaterials are prepared which has more than one phase. Two phases Anatase and Rutile of TiO2 was prepared which are used in industrial paint applications. Composite titanium dioxide considered one of the most important raw material in the manufacture of dyes, especially the white ones because of the white color and brightness, which is owned in addition to the high refractive index and Photocatalyst Properties, especially UV irradiation that associated with surfaces that cleans itself by self and that of the most important characteristics of being hydrophilic materials. In this work Anatase and Rutile phases was synthesis by sol-gel method and mixture of different concentration of the above phases of titanium dioxide with the use of polyethylene glaycol (PEG) as a dispersant were mixed by magnetic blender then added gradually to the local paints on the market. This addition are made using an electrical blender. The results of this work have been investigated and examined using transmission electron microscopy (TEM) and electron microscopy scanner (SEM) to examine and determine the size and shape of nanoparticles added to local dyes. The optical absorbance of TiO2 nanoparticles was measured by UV-Visible Spectrophotometer in order to estimate such as the energy gap and the X-ray diffraction (XRD) device to determine and identify the phase of the nanoparticles that are mixed and which are in two phases as well as the use of Zeta-potential device to determine the surface charge and then stability of nanoparticles(for two phases of titanium doxide nanoparticles), and finally the study of the effective influence of the particles of titanium nanoparticles on local dyes by improving the Iraqi standard of local paints through the most Local paints through the most important tests related dyes Washability and examine the contrast.
