Abstract

The obtaining of intelligent materials requires strict control of physical and chemical parameters that characterize them. In most cases, especially in the case of the nano- or microcomposite structures, the parameters to be controlled and quantified are of morphological and topological nature. This is a direct consequence of the fact that the chemical and physical properties of the nanoparticles and composite materials are strongly dependent on the geometric dimensions. In order to obtain certain material structures a strict control and conditioning of the nanostructured morphology and topology elements entering the composition of the material base is required. By controlling these parameters one may change the surface physical and chemical properties of the component structural elements (electrical and magnetical polarizability, interface free energy, etc.) so as to set a series of phase equilibria that should favour the obtaining of the desired structural properties. This paper proposes an analytical model for solving the morphology and topology which characterises the functionalized nanostructures. This model allows the establishment of analytical connections between real morphological and topological parameters, and the optoelectronically acquired data. Also, the analytic model allows the finding of its own values which characterize the morphological and topological structure of the nanostructure elements..
