Fiber-reinforced tough hydrogelsTough hydrogelHydrogel compositeFiber pulloutUsing strong fibers to reinforce a hydrogel is highly desirable but difficult. Such a composite would combine the attributes of a solid that provides strength and a liquid that transports matter. Most hydrogels, however, are ...

Drawing inspiration from natural materials, a new practical strategy for fabricating strong, tough and fatigue resistant hydrogels is reported by compositing modulus-contrasting, but compositionally similar, hydrogel fibers and matrix together. The strategy is generalizable to various fabrication methods such...
Strong Fiber Reinforced HydrogelIn biological hydrogels, the gel matrix is usually reinforced with micro- or nano-fibers and the resulting composite is tough and strong. In contrast, synthetic hydrogels are weak and brittle, alt ...In biological hydrogels...
Collagen fiber-reinforced, tough and adaptive conductive organohydrogel e-skin for multimodal sensing applicationsdoi:10.1039/D4TB00374HConductive hydrogels (CHs) with high sensitivity and multifunctional property are considered as excellent materials for wearable devices and flexible electronics.

In contrast, biological hydrogels are tough and strong due to reinforcement with nano to micron size fibers. Our work is focused on designing new class of hydrogel assemblies based on fiber reinforced hydrogel composites. In analogy to the spinning of a spider web, a pultrusion system was ...
The hydrogels with a size of 30 mm × 3 mm × 3 mm were freeze-dried by liquid nitrogen and broken into half for exposure of cross sections to SEM. Gold powder was sprayed on the samples prior to microscopy. A scanning electron microscope (TM 3000, Hitachi, Tokyo, Japan) was used to...
Over hundreds of millions of years of evolution, nature has produced a myriad of biological materials that serve either as skeletons or as defensive or offensive weapons. Although these natural structural materials are derived from relatively sterile natural components, such as fragile minerals and duct...
In biological hydrogels, the gel matrix is usually reinforced with micro- or nanofibers, and the resulting composite is tough and strong. In contrast, synthetic hydrogels are weak and brittle, although they are highly elastic. The are many potential applications for strong synthetic hydrogels in ...
