Nanomechanical Analysis of Hybrid Silicones and Hybrid Epoxy Coatings—A Brief Review

Abstract

This review article is written on the investigations of nanomechanical properties of coatings by using nanoindentation techniques. The focus is on the studies that were conducted on epoxy polymer, silicones and their hybrid materials. The article describes a large number of developmental studies that are conducted on coatings. Materials properties such as nanoindentation hardness, modulus, scratch, wear and viscoelastic behavior have been described. Moreover, the article summarizes various studies that mention the use of different nanoparticles in coating formulations that could improve the mechanical strength and service life span of the coatings. The mode and mechanism of material's failure has been outlined and discussed.

Effect of sulfuric acid solution on thermal conductivity and impact strength of epoxy resin reinforced by silicon dioxide powder

“…The thermal conductivity is different depending on the type of material and the nature of the movement of the molecules Solid conductive materials, in which free electrons are responsible for the transmission of heat energy as well as phonons, In heat-insulating polymers where there are no free electrons, the heat is transmitted by flexible waves, due to the oscillation of the particles, as a result of the proximity of the molecules and their association with the bonds, this oscillation will move to the neighboring molecules so The heat is then transferred and these flexible waves are called phonons [7]. Fig.1 shows the method of measurement of thermal conductivity thermal conductivity can be calculated from the following relationship [8]:…”

The study of the bending property of the epoxy (Ep / MgO) and (Ep/SiO2) composites in natural conditions and after immersion in chemical solution

“…And their homogeneous distribution within the base material will reduce the amount of deviation and thus increase the Young's modulus [18,19]. Fig.…”

Nanoscale Characterization of Glass Flake Filled Vinyl Ester Anti-Corrosion Coatings

“…These types of tests are even more complicated and also limited by the properties of the glue. The mechanical properties of coatings can be evaluated by using the nanoindentation test [19,20]. In addition, nanoindentation can be used to estimate the fracture toughness of coatings, which cannot be measured by other conventional penetration tests [21].…”
