Nanoporous materials with a pore size ranging from 1 nm to 100 nm have demonstrated applications in a number of multidisciplinary fields. In particular, the large internal surface area of nanoporous materials optimizes their use as a functional structure which absorbs or interacts with atoms, ions, and molecules. In this study, we first demonstrated co-continuous phase separation morphology with a nanometer scale using spinodal decomposition of polymer blend, which is homopolymer /random copolymer blend with mild interaction strength. Selective extraction of random copolymer led to co-continuous nano-channel, but thin wetting layer of the homopolymer-rich phase at the surface due to lower surface energy of homopolymer resulted in closed surface. Next, UV ozone surface treatment was introduced to achieve open surface of nanoporous thin film as well as increasing wettability. It was confirmed that the nanoporous film can be used as a template for interpenetrating network morphology. |
