Mechanical Properties of Composite Films Reinforced with Ceramic Tin Oxide Nanoparticles

In this paper, the mechanical properties of thin films of filled ethylene-vinyl acetate copolymer and specially synthesized tin oxide nanoparticles are investigated. Tin oxide nanoparticles synthesized in a plasma discharge under the action of ultrasonic cavitation have a size of 50–60 nm, and under ultrasonic exposure, the particle size is 30–40 nm. Using these two types of nanoparticles (before and after ultrasonic exposure), samples of films from composite materials were obtained and studied. The results of studying the fractures of films obtained at the temperature of liquid nitrogen by scanning electron microscopy show that the structure of the material is integral, there are no visible large defects and cavities. Physical and mechanical tests of a film made of a composite material with different contents of tin oxide nanoparticles were carried out. The results of mechanical tests show that ultrasonic treatment of tin oxide nanoparticles before their impregnation into a polymer matrix has a positive effect on the physical and mechanical properties of films made from the studied composite material.
