Project: Tough Hydrogels with fast, strong and reversible underwater adhesion based on a multi-scale design
Abstract: Hydrogels have promising applications in diverse areas, especially wet environments including tissue engineering, wound dressing, bio-medical devices, and underwater soft robotics. Despite strong demands in such applications and great progresses in irreversible bonding of robust hydrogels to diverse synthetic and biological surfaces, tough hydrogels with fast, strong, and reversible underwater adhesion are still not available yet. In this work, we propose a strategy to develop hydrogels demonstrating such characteristics by combining macro-scale surface engineering and nano-scale dynamic bonds. Based on this strategy, we obtained excellent underwater adhesion performance of tough hydrogels with dynamic ionic and hydrogen bonds, on diverse substrates, including hard glasses, soft hydrogels, and biological tissues. The proposed strategy can be generalized to develop other soft materials with underwater adhesion.

Project: Ductile “Ice” : A frozen hydrogel with high compressive strength and ductility
Abstract: Ice, the solid state of water, which mainly consists of a hexagonal crystal structure in bulk, is usually very brittle. Although ice appears less brittle under compression or shear at relatively low strain rate, it is by no means a ductile material as metal and has seldom been considered as an engineering material in applications other than igloos. We report herein the astonishing metal-like ductility of a polymeric hydrogel in a frozen state. Containing 88 wt% of water, the hydrogel appears just like ice when frozen, and embraces most other physical properties of ice. At the same time, the frozen hydrogel is ductile enough to sustain bending, twisting, stretching, extensive shaping, and even machining in a large low temperature range. The ductility at high strain rate also makes it a material with significant impact resistivity. The frozen gel also exhibits the reusable ability – the large plastic deformation is completely recoverable at an elevated temperature. The reusable ductile “Ice” can find various applications in engineering materials used in low temperature range such as drilling for oil and wind power generation in Arctic or Antarctic regions and they can also be used as a low-cost ice substitute when ductility and reusability is required.
