The influence of metal nanoparticles on the mechanical properties of composite materials

Abstract

ExtEndEd AbstrAct:The article presents the results of studies on changes in mechanical and physical properties of polymeric construction materials after the introduction of metal nanoparticles. As an example of metal nanoparticles the influence of nanoparticles of copper has been considered. The ways of formation of copper with dimensions of nanometers, a brief methodology and structure of the obtained filler are shown. Copper nanoparticles have unique anti-bacterial, thermal and conductive properties. These properties substantially remain in the polymer material. The resulting composite material has technological properties of polymers and unique physical properties of the filler.Polymer material was selected among the products of large-tonnage production: polyvinyl chloride, elastomers, polyethylene, polypropylene, polystyrene. The selection of copper ions from the nanoparticles depends on the type of stabilizing agent and on the chemical nature of the environment. The performance of antimicrobial properties in polymer materials is achieved by the dosage of copper in the amount of 1-2% by weight. To give a material the conductive properties of copper nanoparticles a higher concentration of metal is required. To use only
