Nanocoating is the result of a coating application of nanomaterials to build a consistent network of molecules in a coating or paint to protect surfaces of various materials. Boron nitride (h-BN) is in 2D form with excellent thermal and chemical stability. Graphene is an allotrope of carbon in the 2D form and a hexagonal lattice with extraordinary physical and chemical properties. By adding functionalized Graphene or h-BNs into paints or coatings, they will absorb the harmful UV part of sunlight, prevent coating degradation, and the impact of the environmental factors on the coatings to enhance longevity and durability. In this study, graphene & h-BNs were modified with [3- (2-Aminoethylamino) propyl] trimethoxysilane and uniformly added into the polyurethane paint with different amounts to increase hardness, water resistance, and decrease UV degradation of substrates. The samples were characterized by using Fourier Transform Infrared Spectroscopy (FTIR), UV Vis, Scanning Electron Microscope (SEM), water contact angle, and Differential Scanning Calorimetry (DSC).
