“…In the literature, there are many investigations of metal oxide coatings on polymers such as polycarbonates (PC), poly(ethylene terephthalate) (PET), poly(methyl methacrylate) (PMMA), polydimethylsiloxane (PDMS), polyimide, poly(propylene) (PP), etc. [4,6,[15][16][17] While in most of these studies, silicon oxide (SiO x ) was deposited on the polymers, aluminum oxide (AlO x ) has received little attention. Yet, AlO x has remained one of the most widely used metal oxides for nonpolymeric surfaces due to its combination of wear resistance, high thermal and chemical stability, and electrical resistivity.…”

Aluminum‐oxide‐coated PLA pellets, particles derived from aluminum oxide sol‐gel, and calcinated α‐Al2O3 powders were used to fabricate PLA/AlOx composites. The formation of aluminum oxide was confirmed by FTIR and EDS. SEM images suggested the melt compounding system provided a fairly homogeneous dispersion of AlOx particles in the PLA matrix. XRD analysis showed PLA and PLA/AlOx composites were both amorphous. The incorporation of AlOx particles did not alter the melting temperature of PLA. However, the shape and intensity of the melting endotherms was significantly changed, suggesting bimodal melting behavior. UV‐Vis transmission spectra suggested that PLA/AlOx composites may act as a better UV barrier than neat PLA.magnified image

“…These coatings are often produced by physical vapour deposition [1][2][3][4], chemical vapour deposition [4][5][6], and sol-gel coatings [7][8][9][10]. The coating properties can be tailored by controlling the deposition parameters and coating composition according to different functional requirements.…”

“…For example, Wu et al [25] incorporated colloidal silica in the coating formulation that was prepared with 3-glycidoxypropyltrimethoxysilane, tetraethylorthosilicate and ethylenediamine (EDA). The cross-linking density, hardness, fracture toughness and elastic modulus were increased on addition of EDA and colloidal silica.…”

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.
