Abstract

The samples obtained by the Hammer method and then doped with 5, 10 and 15 percent gadolinium were studied by the EPR analysis method. The conducted studies were carried out at room temperature. Depending on the degree of addition of gadolinium during the studies an increase in the intensity of the signal and a decrease in the intensity of free radicals were observed. So that, when the amount of gadolinium reaches 15%, the signal of free radicals disappears. The reason for this is that the Gd ion forms a single homogeneous system with the formation of strong bonds between the surface of the graphene oxide sample. In addition, it can be noted that unpaired electrons in the form of free radicals, which are stabilized in the carbon rings in the crystal structure of graphene oxide, cause this connection.
