Abstract

One of the technologies that are being develop for self cleaning applications is to utilize TiO2 photocatalytic material through a photocatalytic chamical reaction process assisted by the energy of ultraviolet rays. Photocatalytic effect decomposes the impurities in the form of organic compounds. TiO2 synthesized by using precusor of TiCl3. The synthesis uncorporates ammonia washing and calcination at 300 celcius degree for 4 hours to obtain TiO2 solution was coated on the glass sample in the form of paste made by mixing PEG 4000, chloroform, and TiO2 powder. TiO2 composition was varied, i.e. 0 gram, 1 gram, 1,5 grams, 2 grams, 2,5 grams, while PEG and chloroform amounts fixed for all variations observed. Coating were was under taken by the doctor blade technique. Self cleaning testing was using two types of impurities, namely mud and dyes. The test was done in two ways, namely hydrophilic and photocatalytic properties tests. The results showed that the best self-cleaning properties was obtained on the sample with a compositionof TiO2 of 3 grams with the ability to eliminate impurities up to 96% under direct sun and 74% in UV radiation. It has a transmittance difference of up to 58,8%. The hydrophonic properties depend on photocatalytics. However, due to profuse agglomeration of TiO2 the hydrophilic properties decreases.
