A relationship between viscoelastic properties and morphology of the nanomatrix-structured material, in comparison with that of the island-matrix structured material, in which the nanomatrix structure and island-matrix structure were formed by graft-polymerization of styrene onto natural rubber latex, was investigated. Three-dimensional observation of the nanomatrix structure was carried out with a field emission scanning electron microscopy equipped with focused ion beam (FIB-SEM) and transmission electron microscope (TEM) and transmission electron microtomography (TEMT). It was observed when nanomatrix structure was formed in natural rubber, the value of plateau modulus of rubber significantly increased in comparison to that of natural rubber. Meanwhile, the plateau modulus increased slightly when the island-matrix structure was formed in natural rubber. Nanomatrix structures was proven to be a suitable structure to improve the viscoelastic property of rubbery material.
