Morphology design in 2D confinement


Block copolymers

We are investigating the self-assembly of block copolymers in pores with diameters ranging from 20 nm to a few microns in order to fabricate nanorods and microrods with specific internal microphase structures (Fig. 1), as well as mesoporous nanorods and microrods (Fig. 2).
