| Outline of Final Research Achievements |
Using the silica/ polypropylene (PP) and silica/epoxy resin nanocomposite systems as examples, a novel design and functionalization of nanocomposites have been investigated based on interfacial control between polymer and dispersed ultra fine inorganic particles. For the former system, the nanocomposite having both of rigidity and toughness could be fabricated by control an adhesive force acts at silica-PP interfaces. For the latter one, a chemical interaction between the hydroxyl groups on hydrophilic surfaces of dispersed nanosilicas and epoxy matrix might restrict strongly thermal molecular motion of the epoxy polymer chains, resulting in considerable reduction in the its thermal expansion coefficient and elevation of the glass transformation temperature. The results obtained in this study suggest that an interfacial control between polymeric matrix and dispersed inorganic nanoparticles might be a potential candidate for useful design criteria to develop innovative nanocomposites.
