International. Iranian scientists produced epoxy/polyamide coatings with better anticorrosive and physico-mechanical properties by using zinc oxide nanoparticles.
Researchers from the Universities of Amir Kabir and Petroleum Industry say that the use of coatings based on nanoparticles significantly increases the useful life of metal structures.
Due to the small particle size and high specific area, zinc oxide nanoparticles are able to create a physical barrier against the diffusion of corrosive compounds in the coating and on the surface of the metal. They also reduce the reach of corrosive materials to the metal surface, which allows to increase the service life of the structure.
In this research, epoxy/polyamide coatings were formulated in various concentrations of zinc oxide nanoparticles. The raw samples were then obtained by exposing the nanocomposite coatings to the previously prepared metal bottoms. The samples were synthesized by heating them in the oven at a specific temperature and time. Finally, the properties of the coatings were determined by carrying out several experiments.
