Particle-Nested Inverse Opal Structures as Hierarchically Structured Large-Scale Membranes with Tunable Separation Properties |
| 초록 |
A novel multiscale porous architecture where an individual particle is nested inside a hollow chamber of inverse-opal (IO) frame is created using a large scale self-assembly of core–shell structured colloidal particles and subsequent selective removal of the outer shells of the colloids. Since the nested particle is smaller than the size of individual IO chamber, the interconnected nanochannels are spontaneously formed within the structured frame. Since the nanochannel size can be controlled in a range between 5 and 50 nm and the membrane structure is demonstrated over a large area (2-inch wafer) in the form of free-standing films, CPN-IO structures can be applied for the separation of nanoparticles with high selectivity. In addition, we present theoretical calculation for estimating the effective nanochannel size inside the CPN-IO by means of constructing a relevant geometric model. |
