Development of Anticorrosive Polymer Nanocomposite Coating for Corrosion Protection in Marine Environment

Abstract

The marine environment is considered to be a highly aggressive environment for metal materials. Steels are the most common materials being used for shipbuilding. Corrosion is a major cause of structural deterioration in marine and offshore structures. Corrosion of carbon steel in marine environment becomes serious due to the highly corrosive nature of seawater with high salinity and microorganism. To protect metallic materials particularly steel against corrosion occurrence various organic and inorganic coatings are used. The most used are the polymeric protective coatings. The nanostructured TiO2 polymer coating is able to offer higher protection to steel against corrosion, and performed relatively better than other polymer coatings.

Nanocomposite coatings on steel for enhancing the corrosion resistance: A review

“…[27][28][29] NPs were observed to modify the surface energy of the inherently hydrophobic siloxane polymers and hence improve the performance of nanocomposite coating immersed in aggressive media. 30 There are a number of ways to improve the properties of nanocomposites by incorporating NPs, fibers, glass beads, etc. Reinforcements are found to improve thermal resistance, corrosion resistance and mechanical properties of metal matrix due to their unique properties.…”

“…A wide range of epoxy resins are produced industrially for different technological applications. 39 Mardare et al 30,40 experimented with the effect of pristine and TiO 2 incorporated epoxy paint on the corrosion properties of naval steel plates immersed in sea water. A two component polyamide with glossy acrylic PU was coated at a thickness of $80 mm on steel.…”

“…Polymer nanocomposite coatings have been thoroughly investigated in which their applications span from imaging, anticorrosion, marine, smart packaging materials, automotive industry to high technology applications [ 145 , 146 , 147 ]. Nanocomposite coatings can provide high-efficiency gas barrier to the substrate foil [ 148 ] and they can provide superior anti-scratch and anti-corrosion properties.…”

“…Mardare and Benea [117] evaluated the performance of anticorrosive polymer nanocomposites coatings in the marine environment. For this purpose, they selected naval steel for the experiments in sea water.…”

“…Three steel surfaces named as E32 uncoated steel; E32 with primer (painting) and E32 with primer + TiO 2 nanoparticles were prepared to evaluate their performance against corrosion in seawater. From the results, it was found that the corrosion rate was very high in the case of E32 uncoated steel [117]. Contrarily, E32 with primer + TiO 2 nanoparticles surface layer showed a tremendously lower corrosion rate which indicated that nanoparticle coatings have higher corrosion resistance in seawater as shown in Figure 12.…”
