Abstract

TiO2 anatase and rutile having composition of 1%, 1.5%, and 2 % have been applied as a self-cleaning in water based paint containing dispersant polyethylene glycol (PEG) with molecular weight of 6000. Anatase TiO2 is used for self-cleaning and rutile TiO2 for ultraviolet protection. Mud and dye were used as pollutant for self cleaning test. Atomic Force Microscopy (AFM) was employed for evaluating TiO2distribution. Image J was used to calculate area of pollutant and distribution of TiO2. The results show that 2% TiO2 with ratio of anatase : rutile 90:10 has the minimum pollutant area indicating the best self cleaning properties. FTIR characterizations show absorbance peak at 1080 cm-1 wave numbers indicating characteristic peaks of PEG. The increase of peaks at around that wave number indicates maximum TiO2 aggregation. It was found that 2% TiO2 with ratio of anatase : rutile 90:10 has the minimum peak at that particular wave number. The AFM image for this composition shows that aggregate distribution of TiO2 in the film paints are more homogenous compare with other samples leading to an improved self cleaning properties.
