Figure 1

Schematic procedure for the fabrication of embossed polymer brush nanodots and their corresponding AFM images.

The schematic cartoons and their corresponding AFM images are shown as follows: (a and A), diblock copolymer template of PS-b-P4VP; (b and B), etched nanopits; (c and C), initiator monolayer covalently bound to nanopits; (d and D), PMAA brush nanodots. The three steps are as follows: (1) wet etching, (2) initiator grafting and (3) SI-ATRP. The physical meanings of the schematic labels are illustrated at the bottom.
