Nanotechnology is a branch of science and engineering that involves the synthesis, modification, characterisation and application of nanoscale materials in diverse fields. They provide excellent surface coverage and are successfully used as corrosion inhibitors. However, most of the nanomaterials are not effective and require special treatments or modifications for proper anticorrosive activities. The present review article features the current approaches and practices that have been adopted to enhance the anticorrosive performance of nanoscale materials. One of the most growing interests in this direction is the use of covalently and non-covalently functionalised nanomaterials. The functionalised nanomaterials show remarkable improvement in corrosion protection performance. The covalently functionalised nanomaterials show better dispersibility and thereby better efficiency in aqueous electrolytes. In the anticorrosive formulations, nanomaterials avoid the penetration of corrosive species and thereby increase durability and corrosion inhibition. The nanomaterials in anticorrosive formulations also enhance weathering resistance, UV resistance, mechanical performance, thermal stability and hydrophobic property.

The purpose of this study is to determine the impact of nano-clay and nano-silica particles on the vibrational characteristics of composite cylindrical panels in corrosive environments. In this context, due to the presence of diluted sulfuric acid as the corrosive solution, the coupling effects of material degradation and hygroscopic loading on the natural frequencies are taken into consideration. In order to achieve this, it is first explored through experiment how adding nanoparticles affects the coefficient of hygroscopic expansion of the glass/epoxy specimens. Using this coefficient, the in-plane loading caused by corrosive solution is then applied in the equations. The mechanical properties and hygroscopic expansion coefficients of the composite samples exposed to the corrosive environment are first determined by certain experimental testing. The equations of motion are derived using the first-order shear deformation theory (FSDT), and the vibration problem is solved using the generalized differential quadrature (GDQ) technique. Investigation is conducted into the effects of various nanoparticles, immersion time, geometrical elements, and boundary conditions on the natural frequencies of the cylindrical panels. It is found that adding nanoparticles can significantly improve the mechanical properties, the corrosion resistance, and the natural frequencies of composites in which the nano-clay is more effective. For example, adding nano-clay and nano-silica particles, respectively, results in 32.32% and 26.29% increase in elasticity modulus of reinforced glass/epoxy composite. In addition, 12.71% and 47.32% improvements are observed in the natural frequency of the nano-clay reinforced composite panel before and after 90 days of immersion in sulfuric acid. In comparison, the nano-silica particles are responsible for 7.80% and 23.03% increase in natural frequency before and after immersion time.
