Outline of Final Research Achievements

A hygroscopic polysiloxane was synthesized by introducing ionic groups into linear polysiloxane. By mixing this polysiloxane with a lyotropic liquid crystal (LLC), humidity-induced phase transition method was developed. The LLC phase, which is usually manipulated in a solvent such as water, can be controlled by changes in humidity on the substrate. Using this technique, we have created a novel material in which the LLC structure changes in response to humidity at a targeted location in the film, and proposed the possibility of a new mode of photolithography.

Academic Significance and Societal Importance of the Research Achievements

従来は溶媒中でのみ扱われてきたリオトロピック液晶を非水圏でも利用可能なことを実証し、液晶の新たな学理を構築した。さらにこの液晶操作を利活用することで、有機無機複合膜中でナノ構造を簡便に部分変換できるようになり、異種ナノ構造の共存やフォトパターニングが可能であった。自己集合構造を利用した有機無機複合ナノ構造の操作に調湿の概念を導入したことで、従来にないナノ造形が可能となり、新たなリソグラフィ法への展開が期待される。
