Nanostructure fabrication using block copolymers

A brief overview is provided of recent developments in the use of block copolymer self-assembly to create morphologies that may be used to template the fabrication of nanostructures in other materials. The patterning of semiconductor surfaces using block copolymer film masks and the production of high-density arrays of magnetic domains are discussed. The use of block copolymer micelles as 'nanoreactors' to prepare metal and semiconductor nantoparticles is considered, and methods to pattern nanoparticles are highlighted. A number of approaches to design nanocapsules are summarized. Finally, applications of bulk nanostructures to make mesoporous materials with controlled pore structures and sizes, or to create photonic crystals, are discussed.
