摘要：

A new strategy for nanoparticles dispersion into polymer matrix is described in this work. In order to improve the properties of the polyester composites, multiwall carbon nanotubes were chemically coated by a molecular layer of iron (III) oxide. Following a two phases method that includes energy supply into polymer, an optimum ratio between enthalpy and entropy was obtained. Considering physical-chemical interaction inside the dispersed system, during its evolution from raw material to nanocomposite, different types of energy, harmless for the system but acting in the proper direction for an effective dispersion, were applied. XRF, FTIR and SEM analysis were used to emphasis the effect of oscillating magnetic field on nanoparticles dispersion. Also, the influence of dispersion method on composite properties was discussed.
