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
Robust bonding and one-step facile synthesis of tough hydrogels with desirable shape by virtue of the double network structure

TL;DR: In this paper, a pair of hydrogel sheets, containing over 90 wt% of water, were obtained by applying the double-network (DN) structure, and the peeling energy of the united gel sheets reached 1200 J m−2, which is comparable to the bulk fracture energy of a normal type of tough DN gels.
Journal ArticleDOI
A phase diagram of neutral polyampholyte – from solution to tough hydrogel
Abu Bin Ihsan,Tao Lin Sun,Shinya Kuroda,Md. Anamul Haque,Takayuki Kurokawa,Tasuku Nakajima,Jian Ping Gong +6 more
TL;DR: Owing to the reversible ion bonds, the poly(NaSS-co-DMAEA-Q) gels also exhibit complete self-recovery and high fatigue resistance upon repeated large deformation.
Journal ArticleDOI
Friction between like-charged hydrogels—combined mechanisms of boundary, hydrated and elastohydrodynamic lubrication
TL;DR: In this article, the effects of normal stress, gel elasticity and sample thickness on the velocity dependence of friction between polyelectrolyte gels are investigated by using a normal strain-controlled rheometer with a parallel-plates geometry.
