Journal ArticleDOI
Physical hydrogels composed of polyampholytes demonstrate high toughness and viscoelasticity
Tao Lin Sun,Takayuki Kurokawa,Shinya Kuroda,Abu Bin Ihsan,Taigo Akasaki,Koshiro Sato,Md. Anamul Haque,Tasuku Nakajima,Jian Ping Gong +8 more
TL;DR: It is reported that polyampholytes, polymers bearing randomly dispersed cationic and anionic repeat groups, form tough and viscoelastic hydrogels with multiple mechanical properties.
Journal ArticleDOI
Oppositely charged polyelectrolytes form tough, self-healing, and rebuildable hydrogels
Feng Luo,Tao Lin Sun,Tasuku Nakajima,Takayuki Kurokawa,Yu Zhao,Koshiro Sato,Abu Bin Ihsan,Xufeng Li,Honglei Guo,Jian Ping Gong +9 more
TL;DR: A series of tough polyion complex hydrogels is synthesized by sequential homopolymerization of cationic and anionic monomers, which are self-healable under ambient conditions with the aid of saline solution and can be built from their microgels, which is promising for 3D/4D printing and the additive manufacturing of hydrogel.
Journal ArticleDOI
Phase-Separation-Induced Anomalous Stiffening, Toughening, and Self-Healing of Polyacrylamide Gels.
Koshiro Sato,Tasuku Nakajima,Toshiyuki Hisamatsu,Takayuki Nonoyama,Takayuki Kurokawa,Jian Ping Gong +5 more
TL;DR: Novel, tough, strong, and self-healable poly-acrylamide (PAAm) gels are fabricated by inducing an appropriate phase-separation structure using a poor solvent, providing the gels an anomalously high modulus, fracture stress, and fracture energy.
