文摘

Thin films of block copolymers with hierarchical microstructures were fabricated. The fabrication process involves in solution self-assembly and interface adsorption. The microstructures can be tuned finely by varying the experimental parameters. The length of the blocks affects the microstructures greatly. The SERS and catalytic properties of the microstructures were investigated.
