Revolution in Material Science: Creation of Durable Hydrogels

There is a major breakthrough in the field of material science as scientists have developed a unique method for producing slippery hydrogels. These hydrogels are precise, resistant to drying, and have potential uses in several industries including tissue development, wound care, and soft robotics. This discovery is made and published by researchers in The International Journal of Extreme Manufacturing through work done at the Reader Wall.

Incorporation of Trehalose in Hydrogels

The research was conducted at Lanzhou Institute of Chemical Physics using a natural substance known as trehalose. Trehalose, due to its strong hydrogen bonding ability, when added to hydrogels, boosts the overall strength and durability of the gel. This material then forms a surface layer that withstands dryness, maintaining the suppleness, lubrication, and other mechanical properties of the hydrogel. Practically it means that these hydrogels can now face harsh weather conditions without falling apart.

Enhanced Precision for 3D Printing

The integration of trehalose has other benefits too. It not only amplifies the resilience and lubrication of the hydrogel but also boosts the precision during the making process. It helps in preventing any distortion caused by dryness during the development of intricate structures of hydrogels using 3D printing technique. This could fundamentally alter the fabrication processes of hydrogel materials, providing new avenues for their implementation.

Expansion of Hydrogel Applications

Research lead, Xiaolong Wang and first author, Desheng Liu have faith that this new method could open new doors in the field of building manufacturing techniques. The developed hydrogels, which are resistant to drying, could expand the uses of structural hydrogels in different settings. These hydrogels could be utilized in designing wound dressings that can retain moisture or in soft robotics which require suppleness and precision. The possibilities for implementation are indeed diverse and consequential.
