Nano-ordered regular arrangement of crystalline and liquidcrystalline phases in block copolymers and its applicability to storage medium materials

采用微相分离技术将结晶-非晶嵌段共聚物和液晶-非晶嵌段共聚物按几十纳米的顺序排列。揭示了晶体和液晶相变引起的微相分离结构的变化。特别是发现了紫外光异构化引起的相变引起的微相分离结构的变化。在这里获得的知识表明了应用于开关或存储介质材料的潜力。

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.
