Contents I. Introduction
The dispersion of nanoparticles in polymeric material is quite difficult if the nanopowders are not wetted on the surface or are agglomerated in the dispersion medium. The optimization of the modification / wetting of the surface of the nanoparticles is achieved by the variation of the organic additives. The dispersion process of the nanoparticles takes into account both the nature of the dispersion medium (high viscosity) and the process and type of equipment used for dispersion. The dispersion of nanoparticles is very difficult due to the high molecular weight of the used polymeric binders and the weak wetting properties of these binders (viscosity, relatively non-polar character). In principle, the dispersion of nanoparticles consists of three distinct stages: i) wetting, ii) deagglomeration and distribution, and iii) stabilization. These three stages have a great influence on the physico-chemical characteristics of the compounds in the role of paints and primers, [1], [2], [3].
