Effect of nanoparticles on mechanical properties in composite coated materials enhanced by metal nanoparticles

Abstract

The development of modern high-tech urgently needs high-performance materials with low elastic modulus, high yield strength, and large elastic strain performance. However, traditional metal materials lack the characteristics of combining the advantages of these high-performance materials. The metal nanoparticles, with super large elastic strain and ultra-high yield strength, enhance the incomparable superior performance of traditional single materials and have a wide application prospect in many modern high-tech industries. In addition, the nanoparticles will reunite in the collective, which has a certain impact on the mechanical properties of the composite coating materials. Several metal nanoparticles were selected as reinforcing materials and epoxy resin polymer as a matrix material to explore and analyze the influence of nanoparticles in the composite coating materials of metal nanoparticles. The hydrothermal method was used to enhance the properties of the epoxy resin polymer, disperse the epoxy resin, make the Huangyang resin composite coating, and study the effect of nanometer content on the mechanical properties of the composite coating. According to the research results, the appropriate amount of nanometers can optimize the performance of the coating of epoxy resin. When the number of nanoparticles added is 0.05%, the mechanical properties of the coating reach the best.
