To observe the self cleaning effect, the leather samples to which nano TiO2 had been applied and control samples were stained with mud , coffee and sebum. The stained samples were exposed to UV for 24 hours. It was determined that leather samples treated with nano TiO2 exhibited a photocatalytic effect and a self cleaning effect, which increased depending on the amount of nano TiO2.Note de contenu : - Materials
