Functional Macromolecular Materials
Block copolymers provide an ideal platform to control and modulate the interaction of visible light with matter on the nanoscale. Compared with other materials used in bottom-up self-assembly, such as colloids, BCPs offer several advantages, including rapid kinetics, macroscopic ordering of self-assembled structures, and high tolerance for functional additives. By tuning the molecular structure of the underlying BCPs, they can be directed to form more complex microstructures. A wide variety of photonic architectures, ranging from long-range ordered structures (e.g., closely-packed micelles, hexagonally-packed cylinders, double diamond, gyroids, cubic, and correlated networks) to systems with short-range order like photonic glasses, have been successfully self-assembled from BCPs.
We are particularly interested in
the synthesis of biocompatible and biodegradable BCPs systems;
the kinetics of the BCPs self-assembly process, how the confined self-assembly of BCPs within a droplet can be used to produce photonic structure;
methods to enhance the self-assembly or to add functionality;
manufacturing functional materials based on macromolecular systems.
