| Research Abstract |
Various mesoporous polymeric materials have been developed and they are considered as potential candidates for advanced separation materials. It is still challenging, however, to develop economically viable and durable separation materials from low-cost, mass-produced materials. Here we investigated the fabrication of a nanofibrous network structure from common polymers, based on a microphase separation technique from frozen polymer solutions. The resulting polymer nanofiber networks exhibit large free surface areas as well as mesopores. These mesoporous polymer materials are able to rapidly adsorb and desorb a large amount of carbon dioxide and are also capable of condensing organic vapors. Furthermore, the nanofibers made of engineering plastics exhibit surprisingly high, temperature-dependent adsorption of organic solvents from aqueous solution.
