生命科学時代の新材料―高弾性・高靭性ダブルネットワークゲル― Double Network Hydrogel with High Modulus and Toughness: A Novel Material for Load-Bearing Soft Tissues

グン　剣萍 Jian Ping GONG

＜要旨＞Hydrogels attract attention as excellent soft & wet materials. However, common hydrogels are mechanically too soft and brittle to be used as load-bearing materials. By mimicking the structure of the articular cartilage which is one of the native tough hydrogels, Double Network hydrogel (DN gel) with extremely high mechanical performance has been developed. DN gels, consisting of rigid and brittle polyelectrolyte network as the 1st component and soft and ductile neutral network as the 2nd component, exhibit 0.1-1 MPa of elastic modulus, 60 MPa of compressive fracture stress, 3000% of tensile strain, and 2500 J/m2 of fracture energy. Such a tough hydrogel has an excellent mechanical compatibility with load-bearing soft tissues such as articular cartilages. Keywords: Hydrogel / High Elasticity / High Strength / Double Network Gel / Toughness / Polyelectrolyte / Mechanical Compatibility / Artificial Cartilage
