Abstract
Abstract In this work, the synthesis of titanium dioxide nanoparticles in plasma discharge was carried out under ultrasonic cavitation. It was found that applied acoustoplasma method allows to synthesize nanosized particles of titanium dioxide with the controlled shape and narrow size distribution. Polymer composite materials based on synthesized nanoparticles of titanium dioxide and epoxy polymer have been obtained by the in situ method by curing with preliminary ultrasonic dispersing. The composition and structure of the obtained TiO2 polymer composite materials have been studied by scanning electron microscopy. The mechanical properties of the obtained film polymer composite materials were investigated to determine the tensile strength, elastic modulus and relative deformation. It was found that nanoparticles in optimal concentration (3%) lead to the reinforcement of obtained composite materials.
