“…Amerio et al [54] formulated hybrid coating by a dual curing process that combined sol-gel reaction with UV light induced polymerization. Authors incorporated bisphenol-A ethoxylate dimethylacrylate as an organic binder, methacryloxypropyl-trimethoxysilane as coupling agent and TEOS as crosslinker.…”

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.

“…In the past decades the development of organic-inorganic composites containing polymeric phases as the organic component [1][2][3][4][5] and further on polymer nanocomposites [6][7][8][9][10] has been receiving a great deal of attention due to the unique combination of light weight, processability of polymers with the outstanding chemical and thermal stabilities of the inorganic components. This technology was extended to different fields, which includes, reinforced polymeric materials, polymeric membranes for several application as for instance: gas-separation [11], fuel cell applications [9,12], pervaporation [13,14]; protecting coatings [1,15] to name a few.…”

Alumina nanoparticles were dispersed in poly(amide 12-b-tetramethylene oxide) copolymer through extrusion. The alumina particles were functionalized with 3-(2 trimethoxysilylethyl) cyclohexene oxide. The following PEBAX TM / Al 2 O 3 proportions were prepared: 0.1, 1.0, 5.0, and 10.0% w/w. The thermal stability of the nanocomposites was evaluated by thermograviemtric analysis under N 2 and was comparable to the neat PEBAX TM polymer. The thermo-oxidative degradation of the polymeric matrix by oxygen was strongly hindered by the functionalized alumina. The rule of mixture would predict that the thermal degradation should be strongly dominated by PEBAX TM matrix. Therefore, the physical mixture of PEBAX TM and silanized alumina should be almost as stable as pure PEBAX TM . However, the experimental results suggest that the nanocomposites are more stable than the mixture of their components. This stabilization effect is evident in the temperature range between 300˚C and 400˚C, in which the degradation of the PA12 block takes place.

“…Use of nanosilica showed improvement in the scratch resistance in acrylic based polyurethane automotive coating (Zhu et al, 2008), nano-ZnO imparts UV resistance (Dhoke et al, 2009), whereas nano-CaCO 3 shows hiding power improvement in epoxy powder coatings (Yu et al, 2006). Nanosilica when embedded in acrylic polyurethane based coatings shows improvement in properties like scratch resistance (Manfred et al, 2000;Chen et al, 2005;Amerio et al, 2008;Zhu et al, 2008). Calcium carbonate is a common inorganic compound known as limestone.…”

“…The polymer chains will now be entangled around inorganic particle. Amerio et al (2008) reported synthesis of inorganic nanoparticles functionalised hybrid coatings containing nanosilica. These were obtained by a dual-curing process combining the sol-gel reaction with UV-induced polymerisation technique.…”

Thermosetting acrylic (TSA) resin was prepared by solution polymerisation of acrylic acid and methyl methacrylate (MMA). Hybrid polymer consisting of acrylic polyol-polyurethane was prepared by addition of hydroxy ethyl acrylate and hexamethylene diisocyanate (HMDI). Incorporation of Functionalised nanocalcium carbonate and bentonite nanoclay were accomplished by in situ method during the synthesis of both the polymers. Loading of nano-CaCO 3 and nanoclay was varied from 0 to 4 wt.% to investigate variation in mechanical, optical and high performance properties. The superiority of nanoclay in enhancing the mechanical and performance properties like the salt spray and humidity resistance in comparison to that of nano-CaCO 3 was clearly established. It was also observed that, addition of nanomaterials in hybrid resins system shows superior results compared to neat acrylic system and in situ additions of these nanomaterials improve the dispersion and stability in the matrix.La résine acrylique thermodurcissable (RAT) aété préparée par polymérization en solution de l'acide acrylique et du méthacrylate de méthyle (MAM). Le polymère hybride composé de polyol-polyuréthanne acrylique aété préparé par l'ajout d'acrylate de 2-hydroxyéthyle et de diisocyanate d'hexaméthylène (DIHM). L'incorporation de carbonate de calcium nano et de nanoargile de bentonite fonctionnalisés aété accomplie par une méthode in situ lors de la synthèse des deux polymères. Le chargement du CaCO 3 nano et de la nanoargile variait de 0à 4% pds pourétudier la variation des propriétés mécaniques, optiques et de rendementélevé. On a clairementétabli la supériorité de la nanoargile pour ce qui est d'accroître les propriétés mécaniques et de rendement comme le jet salin et la résistanceà l'humidité en comparaisonà celles du CaCO 3 nano. On aégalement observé que l'ajout de nanomatériaux dans le système de résines hybrides fournit des résultats supérieurs comparativement au système acrylique pur et les ajouts in situ de ces nanomatériaux améliorent la dispersion et la stabilité dans la matrice.
