| Outline of Final Research Achievements |
A novel method for the preparation of microstructure-controlled inorganic/organic composites has been investigated based on self-assembling phenomena of stabilized aqueous suspension systems of polymer latex mixed with inorganic nanoparticles. In this method, during condensing and drying of the suspension systems which have a high dispersion stability without hetero-coagulation, inorganic nanoparticles are trapped as the latex forms the continuous polymer matrix phase, resulting in the preparation of a microstructure controlled composite. By controlling the ratios of particle numbers and diameters of latex and inorganic nanoparticles in the suspension system, the microstructure of the composite could be varied from nano-dispersion type to open- or closed-cell like network one. It was found that the proposed method might possess a potential for a practical technique to product the unique materials which contribute to the reduction of fuel consumption and exhaust gas in motor vehicles.
