OBTAINING THE METAL-CONTAINING NANOPARTICLES IN POLYETHYLENE MATRIX BY MECHANO-CHEMICAL METHOD AND STUDY OF THEIR PROPERTIES
S.K.Ragimova

Metal-containing nanoparticles in the matrix of high-pressure polyethylene are obtained by the mechanochemical method without the use of organic solvents by high-speed thermal decomposition of salts of organic acids under conditions of high shear deformations. The phase composition and structure of the obtained nanocomposites were studied by X-ray phase, scanning electron microscope, and thermogra-vimetric analyzes. It is shown that the formation of nanoparticles of metal oxides in the polymer matrix, contribute to the stabilization of the composite, raising the temperature of the onset of its thermal-oxidative degradation. Micrographs of the obtained nanocomposites indicate the formation of layered structures that possess high fracture toughness.
