Since the 2000s, many breakthroughs in the development of mechanically strong and tough hydrogels have led to enormous advances in the study of soft materials and our understanding of their failure mechanisms. Research has also been conducted on long-term mechanical stability — that is, the ...
The fibrous construct improves the strength, modulus and toughness of the hydrogel and also constrains the swelling. By altering the construct geometry and studying the effect on mechanical properties we will develop the understanding needed to design strong hydrogels for biomedical devices and soft ...
3c. Polyurethane hydrogel is smooth after drying and just a few of fibrous tubes could be observed on surface due to it contains softer segments such as PEG400. However, large amount pores could be observed in the GelMA, which allow cell adhesion and proliferation. While, the pore of GelMA...
hydrogels were brittlely exposed to cross sections with liquid nitrogen and sputtered with gold, followed by SEM (HITACHI SU8220) test. Tensile tests The mechanical properties of hydrogel fibers were tested by using a universal tester (AGS-X) with an environmental chamber and a liquid nitrogen ...

Hydrogels are promising soft materials as tissue engineering scaffolds, stretchable sensors, and soft robotics. Yet, it remains challenging to develop synthetic hydrogels with mechanical stability and durability similar to those of the connective tissues
Natural load-bearing materials such as tendons have a high water content of about 70 per cent but are still strong and tough, even when used for over one million cycles per year, owing to the hierarchical assembly of anisotropic structures across multiple length scales1. Synthetic hydrogels have...
We assemble biomimetic Bouligand-chiral and fibrous structured ceramic aerogels (BcF-CAs) with ultra-strong, superelastic, and thermal insulation properties27. Strikingly, the tensile strength of the obtained biomimetic BcF-CAs is as high as 170.38 MPa, which is one to two orders of magnitude ...
Structure and physical properties We first characterized the structure and physical properties of the hydrogel tapes. Thanks to the excellent flexibility, the hydrogels can be fabricated into various forms such as bandage like strips and double-side tape like rolls (Fig.2a). The color of the Chem...
