Analysis of nitroxyl paramagnetic probe TEMPO rotational diffusion reveals the dynamic heterogeneity of the systems because of their structural inhomogeneity. Optical micro images show that introduction of TEOS into polyimide is accompanied with formation in the system of micro heterogeneities. Their mean size and quantity depend on inorganic part content.
