Abstract

Surface coatings are important in terms of aesthetic and protection against the environmental and harsh conditions such as corrosion, erosion, abrasion, mechanical forces. Importance of coating is due to this fact that by use of a sub-micrometer film special substrates can be protected and find an appropriate role in the application sought. However, improvement in properties of coating is so important and one of the best methods to improve their properties is using nanotechnology. Polyhedral oligomeric silsesquioxane (POSS) is a special type of silica family with the imperial structure of RSiO1.5. This is a cage-like molecule that has been able to take on a special space in coating industry. It can affect mechanical properties (modulus, elongation at break, yield strength, impact resistance), surface properties (hydrophilicity, hydrophobicity, surface friction, and surface roughness), thermochemical properties (curing time and curing behavior), rheological properties, chemical resistance, and permeability. In this chapter, the effect of POSS addition on the mechanical properties, surface properties, flame retardant effect, and corrosion resistance has been studied.
