We controlled the microphase separation structure self-assembled by block copolymers which has 101 nm scale periodic structure necessary for the next nanotechnology. The blend method of low molecular liquid crystal, temperature gradient method and guide substrate method was applied for the film of the block copolymer with liquid crystalline side chain. It was accomplished that regularity of in-plane alignment increased by two orders and the aspect ratio of the structure along out-of-plane direction reached to three orders. Furthermore, we evoluted functionality of the structure film by development of the process of free-standing film and templating process to other materials.
