A new adhesive developed at Nanyang Technological University (NTU), Singapore hardens with the application of low voltage. The adhesive has exciting potential for uses that range from sealing surgical incisions to repairing ships while they are still in the water. The adhesive has been nicknamed “Voltaglue.” Assistant Professor, Terry Steele, was one of the researchers leading the team that developed Voltaglue, and stated: “We had to find a way to make glue which cures (hardens) when we want it without being affected by the environmental conditions, so electricity was the best approach for us. The hardness of our glue can be adjusted through the amount of time we apply a voltage to it, which we call electrocuring.” The research team’s results were recently published in Nature Communications. The ability to modulate hardness with voltage is part of what makes this adhesive exciting. Eventually, the same or similar adhesives could be cured hard enough for boat repair, or cured to a flexible, rubber-like consistency to seal incisions after surgery or secure medical equipment to a person’s skin.
