Here we present a type of hydrogels comprising hierarchical structures of picot fibres made of copper-bound self-assembling peptide strands with zipped flexible hidden length. The redundant hidden lengths allow the fibres to be extended to dissipate mechanical load without reducing network connectivity, ...
Introducing self-healing properties into hydrogels can prolong their application lifetime. However, achieving mechanical strength without sacrificing self-healing properties is still a major challenge. We prepared a series of zwitterionic polymer hydrogels by random copolymerization of zwitterionic ionic ...
203Altmetric Metrics Abstract We develop soft and stretchable fatigue-resistant hydrogel optical fibers that enable optogenetic modulation of peripheral nerves in naturally behaving animals during persistent locomotion. The formation of polymeric nanocrystalline domains within the hydrogels yields fibers with low...
Nanofibrous hydrogels are pervasive in animal and plant bodies and have been widely seen in engineering applications. Electrospinning is one of the most widely used methods for the fabrication of nanofibrous hydrogels. Whereas the biological nanofibrous hydrogels can maintain high strength and high toughne...
The present disclosure relates to triblock and pentablock copolymers and methods of making thereof. Aspects of the disclosure further relate to block copolymer hydrogels that exhibit both fatigue resistance and fracture resistance with superior rates of recovery. 机译:本公开涉及三嵌段和五嵌段和五嵌段...
Most load-carrying materials—plastics, metals, elastomers, hydrogels—have potent natural or engineered tougheners, and fall much below the diagonal: these materials are tough but fatigue-prone. For these tough materials, the threshold is typically lower than the toughness by one to two orders of...

Hydrogels have been extensively studied for applications in various fields, such as tissue engineering and soft robotics, as determined by their mechanical properties. The mechanical design of hydrogels typically focuses on the modulus, toughness, and deformability. These characteristics play important ...
