Cousins of naturally occurring opal gemstones, these materials promise a broad range of novel and tunable properties that could enable new functionalities in applications such as ultrafiltration, microfluidics, catalysis, drug delivery, photonics, and ferroic devices. This project uses theory and experiment to identify colloid-chemical conditions under which ICCs are most easily formed. It seeks to determine practical fabrication conditions as the first step towards assessment of manufacturability and demonstration of prototype materials and devices. If these experiments are successful, they could open up a whole new field of study.
