It is rapidly advancing into formulations of paints, inks and coatings. Nanomaterials fall into three broad categories: metal oxides, nano-clays, and carbon nanotubes. Metal oxide nanoparticles include nanoscale zinc oxide, titanium oxide, iron oxide, cerium oxide and zirconium oxide, as well as mixed metal compounds such as indium-tin oxide and zirconium and titanium, as well as mixed metal compounds such as indium - tin oxide. This little matter has had an impact on many disciplines, such as physics, chemistry and biology. paint and coating nano-decorative needs (eg, color and gloss), functional purposes (eg conductivity, from microorganisms) and protection of paints and coatings (eg scratch resistance, UV stability). Especially in nano-sized metal oxides such as TiO2 and ZnO or aluminum, cerium, silica and nano-sized pigment find application in new paint and coating formulations. When the substance decreases in size it changes its color and interaction properties with other substance such as chemical reactivity. Changes in properties cause changes in electronic properties. By particle size reduction, the surface area of the material is increased. Due to this, a higher percentage of atoms can interact with other substances, for example, with the matrix of resins. Surface activity is an important aspect of nanomaterials. Agglomeration and aggregation block the surface area from contact with other substances. Only well-dispersed or mono-dispersed particles allow the full useful potential of the substance to be used. As a result, good dispersion reduces the amount of nanomaterials needed to achieve the same effect. This aspect is of great importance for the commercialization of product formulations containing nanomaterials, as most nanomaterials are still quite expensive. Today, many nanomaterials are produced in a dry process. As a result, the particles have to be mixed into liquid formulations. This is where most nanoparticles agglomerate during wetting. Carbon nanotubes in particular are very sticky, making it difficult to disperse in liquids such as water, ethanol, an oil, a polymer, or an epoxy resin. Conventional processing devices, for example, high shear or rotor-stator mixers, high pressure homogenizers, and colloid and grinders are insufficient to separate nanoparticles into individual particles. In particular, ultrasonic cavitation is very effective in breaking bulks, aggregates, and even primers for a problem smaller than a few nanometers to double microns. When used for ultrasound milling high-concentration series, streams of liquid jets obtained from ultrasonic cavitation, particles collide with each other up to 1000km/h. This breaks the forces in the Van der Waals Agglomerates and even the primary particles.
