Outline Activities
Professor Kikuchi is a pioneer of polymer-stabilized liquid crystal blue phase, which has a large temperature range of blue phase and sub-millisecond electro-optical response and therefore is emerging as the next-generation display material. He is the recipient of the Award for Encouragement of Research in Polymer Science from the Japanese Society of Polymer Science in 1995, the Outstanding Paper Award in the Polymer Journal in 1995, the Outstanding Paper Award of the Japanese Liquid Crystal Society in 2003, and the Special Recognition Awards from the Society for Information Display in 2009. In 2011, he received the Award of the Society of Polymer Science, Japan and in 2014, he received the Award of the Japanese Liquid Crystal Society for Outstanding Achievement for his leading contributions to the research of the polymer-stabilized liquid crystal blue phase. In recent years, we have discovered the nematic phase, which has a dielectric constant exceeding 10000 and exhibits ferroelectricity(Adv. Mater. 2017). Furthermore, we discovered ferroelectric smectic A phase (Adv Sci. 2022).
Research Interests
