英文摘要： The rheological behaviors and morphological structures of high-filled nanoparticle/rubber series were investigated mainly by using rheology and a combination of other advancing testing methods (low angle X-Ray Diffraction, nuclear magnetism resonance, transmission electron microscopy, etc.) in this application, especially the influence mechanism of the high-filled nanoparticles (network) on the terminal region viscoelasticity and molecular relaxation behaviors of rubbers. On that basis, a filler network structure model which involve with all factor and clear physical image was developed and established. And the dependency relationship between network structural parameters and surface, structural, size, volume fraction of particle and rubber matrix was also determined. Multilayer or multiscale descriptions of the morphological structure and property can realize structural control and optimization of property for high-filled nanoparticle/rubber series. This research is one of the most attractive fundamental theoretical questions, which is closely related to many rheological behaviors of nano-fillers reinforced rubber. The research is the necessary basing on resolving the relationship between the structure and properties reinforced elastomer material and guiding the future accuracy design of rubber formula. Hence, the result of this application will play an important role in further expending the study fields with great theory significance and actual value, which is favored to achieve innovation and highly academic value.
