Abstract
The coatings of TiO2 and SiO2 nanoparticles mixed with latex paint on the sample are studied. The sample coin is coated primarily with latex paint alone and then with additives such as TiO2 and SiO2 nanoparticles separately with the same percentage of concentration. The sample is illumined by a coherent source of light and produces tiny bright and dark fingerprints by the interference effect of the scattered laser. This cigar-like granular pattern image is known as a speckle pattern which is recorded continuously during the drying process of paint. The modified properties due to the additives in paint on the coin are studied by speckle photography. The surface profile plotting method is adopted for the roughness analysis on the sample. Histogram and gray level co-occurrence matrix perform the intensity analysis in the paint. The brightness examine by means of bright/dark pixel counting method.
