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.

“…Hybrid films containing TEOS and MTES showed a decrease in hardness from 1.75 to 0.35 GPa as the MTES content increased [31]. The nature of the organic group bonded to the silica network has a large effect on hardness, for example, hybrids with methyl groups are up to 4 times harder than hybrids with phenyl groups [32]. In addition, hardness varies with synthesis conditions, such as the type and amount of catalyst, the amount of the solvent, and the temperature of heat treatment [33].…”

Melting gels are a class of organically modified silica gels that are rigid at room temperature, flow at temperature T1 and consolidate at temperature T2 (T2 [ T1), when crosslinking is complete. The process of (a) softening, (b) becoming rigid and (c) re-softening can be repeated many times. Mixtures of mono-substituted alkoxysilanes and di-substituted alkoxysilanes have been studied in a systematic way to identify suitable melting gel compositions. The mixtures and the resulting melting gels have been characterized for their softening temperatures and consolidation temperatures. With an interest in using these materials for sealing microelectronics, their physical properties have been measured.

International audienceWe computed by a modified tight binding approximation, the total electronic energy of three different hybrid polymers: H-Sio(2), CH3-SiO2 and C6H5-SiO2. We made the hypothesis that the structures of these polymers are amorphous. Computational results regarding the total electronic energy and experimental data [1] on the toughness of these three hybrid polymers were compared. A good qualitative agreement was found between computations and experiment
