FIELD: nanodiagnostics.
SUBSTANCE: method for analysing the evolution of nanoinclusions in thin-film nanocomposites is disclosed, which consists of measuring the temperature dependence of internal friction using the inverted pendulum method, quantifying internal friction as the inverse of the quality factor of an oscillatory system, by the number of recorded periods of damped oscillations. The temperature dependence of internal friction is plotted based on the values of 1/Q calculated at different temperatures for a series of samples obtained under different synthesis conditions, and the evolution of nanoinclusions is estimated based on the shift of the internal friction peak, establishing the correspondence of the peak maximum to the temperature of the nanoinclusion phase transition from solid to liquid state, a decrease in the area of peaks with a decrease in the characteristic sizes of nanoinclusions under varying synthesis conditions.
EFFECT: invention provides relative simplicity of analysing evolution of nanoinclusions in thin-film nanocomposites.
