Functional crosslinked nanostructures from block copolymers

Nanostructure fabrication from block copolymers in my group normally involves polymer design, synthesis, self-assembly, selective domain crosslinking and sometimes degradation. The preparation of thin film with nanochannels was used to illustrate the strategy we took. The nanochannels generated in thin films functioned as chemical valves. The nanochannels also served as templates for semiconductor or magnetic nanoparticle preparation.
