NTU charges up over glue

Nanyang Technological University (NTU) has revealed an underwater glue which hardens when electricity is applied to it.

Dubbed Voltaglue, the adhesive utilises a hydrogel made from carbon molecules called carbenes which grab onto surfaces when electrified. In addition, the bonding strength of the glue can be controlled by the charge put through it.

Voltaglue, which has recently received a S$900,000 ($629,970) research grant to be further developed, could be deployed by a number of sectors, including oil and gas, shipping, and military areas.

The project has received a patent, and NTU is currently looking at whether it will spin the technology out or license it.
