Free-Standing Nanocomposite Multilayers with Various Length-scales, Adjustable Internal Structures and Functionalities |
| 초록 |
We introduce an innovative method for the preparation of nanocomposite films, which allows accurate control over the placement of functional groups as well as the composition and dimensions of individual layers/internal structure. By employing photo-crosslinkable hydrophobic polymers, nanocomposite films were prepared by an efficient photo-crosslinking layer-by-layer process, without perturbing underlying layers and nanostructures. The thickness of individual layers could be controlled from a few to hundreds of nanometers producing highly ordered internal structure and the resulting nanocomposite films exhibit a variety of physical properties. These include prolonged photoluminescent durability, facile color tuning, and the ability to prepare functional free-standing films that can have the one-dimensional photonic band gap and furthermore be patterned by photolithography. This robust method opens a new route for the design of functional film devices based on nanocomposite films. |
