The morphology was analyzed using light and transmission electron microscopy. The composites were investigated by creep-recovery experiments, in addition to conventional dynamic-mechanical measurements. While the changes of the storage modulus G(') are not very distinctive for low filler concentrations, the differences in the recoverable compliance measured by creep-recovery experiments become significant. The better the quality of dispersion, the higher is the recoverable compliance.
