研究紹介

研究テーマ

Exploring the mechanisms of chemical reactions in soft materials

キーワード

Polymer gels, Functional materials, Fracture mechanisms

研究概要

Before joining ICReDD, I focused on the fracture mechanisms of soft and tough double network (DN) materials mainly from the perspective of polymer physics and fracture mechanics. Now one of my research interests is to understand the mechanisms of special chemical reactions in gel materials combining computational and experimental results.
