Abstract
Initial contact angles have been measured for sessile droplets of dispersions, from which ring-shaped deposits are being formed. Factors that affect the initial contact angles, i.e., the regime of droplet application; droplet volume; method of substrate surface treatment; and the concentration, charge, and nature of dispersion particles, have been analyzed. It has been found that, depending on the method of substrate cleaning, the contact angle may be changed by 47°. At the same time, the regime of droplet application may change the contact angle by 13°. The presence of particles may either increase or decrease the contact angle by 5°, depending on their nature. The structure of a formed deposit has been shown to depend on the contact angle and the degree of chemical homogeneity of a substrate surface.
