Outline of Final Research Achievements

Previous researches on mesoporous polymers have been focused on control of pore size and porous morphology. However, materials design of pore framework has not been deeply investigated. Here we performed fabrication of mesoporous polymers with multi-component polymeric framework. We have developed flash-freezing nanocrystallization method for polymer solutions, which leads to mesoporous polymers with large mesopores volumes as well as high specific surface area. We applied the method to multi-component polymer solutions containing inorganic nanoparticles. The flash-freezing nanocrystallization method successfully gave mesoporous structure of multi-component polymer systems that contains silica nanoparticles and carbon blacks. The nanoparticle-containing mesoporous hybrids gave mesopore volumes larger than 0.5 cm3/g and specific surface area higher than 200 m2/g.
