| Popis: | Anatase is one of a common and favorable material use in the manufacturing industry due to its uniqueness and functional performances to human and environment The study was focused on the performance of anatase mixed with glaze and applied on ceramic tiles by a dip coating method Two different sizes (micron and nano size) of anatase powder were used to observe their performance as antibacterial materials The anatase powder in micron size was varied at 5 wt%, 10 wt % and 15 wt%, whereas nano size anatase was fixed at 10 wt% The anatase powders were mixed with the glaze compound and then coated on the tile surface Sample produced were characterized through physical appearance, scanning electron microscopy (SEM) analysis and antibacterial test Antibacterial testing by using E Coli was done on tiles and was observed by counting the colonies of bacterial growth in 0 hr, 2 hrs, 4 hrs and 8 hrs The addition of anatase slightly change the colour of the tile produced Whereas SEM results show the distribution of anatase powder in the tiles surface The antibacterial properties increased when the composition of anatase increased However, nano size anatase gave better antibacterial properties compared to micron size because of larger surface area of the antibacterial agents on the tiles. |
