Newly Engineered Hydrogel Superglue is 90% Water
Added Nov 10, 2015 | Rate View top rated
MIT engineers have created a synthetic, sticky hydrogel that is over 90 percent water. The hydrogel - a transparent, rubber-like material - can adhere to surfaces like glass, silicon, ceramics, aluminum, and titanium with a toughness comparable to the bond between tendon and cartilage on bone. In experiments to demonstrate its robustness, the researchers applied a small square of their hydrogel between two plates of glass, from which they then suspended a 55-pound weight. They also glued the hydrogel to a silicon wafer, which they then smashed with a hammer. While the silicon shattered, its pieces remained stuck in place. This durability makes the hydrogel an ideal candidate for protective coatings on underwater surfaces such as boats and submarines. Since the hydrogel is biocompatible, it could also be suitable for a range of health-related applications, such as biomedical coatings for catheters and sensors implanted in the body.

What a super idea for securing delicate items, need now to do long term adhesion tests and degradation trials. Looks like it is a candidate for flexible wearable sensors for the battle field troops. Need to look at all possible uses from medical, electrical-electronics to manufacturing structures to hold together and use in flexible body armor supports. Is it now available for evaluations? This is where the US universities excel in this type of out of the box R&D work- we must keep them funded so the research DNA in students minds does not wither or diminish.
