| Research Abstract |
Crystalline and liquid crystalline phases were arranged in the several ten nanometer order employing the microphase separation in crystalline-amorphous and liquid crystalline-amorphous block copolymers. The change in the microphase separation structure caused by crystalline and liquid crystalline phase transitions was revealed. Especially, the change in the microphase separationstructure by the phase transition caused by UV-photoisomerization was found. The knowledge obtained here suggests a potential for application to switching or storage medium materials.
