Abstract

Abstract In the present paper, the degree of the modification depending on the content of carbon copper-containing nanoforms is studied for polymers such as polycarbonate, polymethylmethacrylate and polyvinyl alcohol which have different structure and different content of oxygen bound to carbon. It is shown that for obtaining the maximal degree of the modification of the above polymers, the content of carbon copper-containing nanoforms should be in the range of 10−2–10−3%. In this case the structure of the nano-modified polymers is formed similar to the structure of the nanoforms. The degree of the modification depends on the amount of oxygen atoms in the polymer structure. The larger is the number of oxygen atoms, the smaller is the content of the nanoforms necessary for the polymer modification; in polycarbonate, the modification starts when the content of the nanostructures is 10−5%, in polymethylmethacrylate, the modification is observed at the nanostructure content of 10−4%, and for the polyvinyl alcohol modification the minimal content of 10−3% is necessary.
