Outline of Final Research Achievements

Photoresponsive and mechanical properties of photomoblile polymer materials were controlled by applying composite structures of crosslinked liquid-crystalline polymers and amorphous polymers. Interpenetrating polymer networks (IPNs) containing smectic liquid-crystalline polymers exhibited faster bending and unbending behaviors upon irradiation with UV and visible light compared with conventional systems. The processability of photomobile films were improved by applying semi IPN structures. Furthermore, mechanical properties were enhanced by controlling phase-separated structures of crosslinked liquid-crystalline polymers and amorphous polymers.

Academic Significance and Societal Importance of the Research Achievements

高分子光運動材料は,軽量・フレキシブルで自立可能なソフトアクチュエーター材料として盛んに研究が進められている。本研究では複合構造形成による高分子光運動材料の光応答性・力学特性制御に取り組み,ミクロ構造とマクロ特性との関連を探究した。ミクロ構造制御による物性制御手法の確立は,光アクチュエーターの用途に応じた自在設計に寄与するものである。また本研究における架橋液晶高分子の複合化手法は,光運動材料のみならず他の刺激応答材料にも適用可能であると期待している。
