摘要：

The two-dimensional confinement of symmetric diblock copolymers of styrene and butadiene, Ps-b-PBD was investigated using nanoscopic cylindrical pores in alumina membranes. The alumina membranes were electrochemically prepared in 0.3 M oxalic acid by a two-step anodization process. Transmission electron microscopy (TEM) was used to visualize microphase separated morphology in the copolymer nanorods. The results show that the highly immiscible PS and lower surface energy PBD, segregated to the high-surface-energy alumina interface.
