Self-healing footwear could be on the market before we know it, as domestic footwear manufacturers push the envelope on innovative technologies and manufacturing processes and develop more environmentally sustainable textile solutions. The University of Massachusetts Lowell is working with Poly Labs, BASF, and The Haartz Corporation on behalf of U.S. Army DEVCOM to develop self-healing outsoles for combat boots. USFMA played a leading role in funding the research, which is funded by a $1.1 million grant as part of the R&D initiative Harnessing Emerging Research Opportunities to Empower Soldiers, or HEROES. “Our research is specifically being applied to combat boots, but because of the way we designed this chemistry, it can be broadly applied to all footwear and beyond,” said James Reuther assistant professor of polymer chemistry at UMASS Lowell. Reuther and his lab team are looking to replace rubber outsoles with polyurethane, a lighter synthetic resin that is easier to break in and more comfortable. And newly created dynamic chemical bonds that are incorporated into the polyurethane offer the promise of self-healing properties to enable tear to self-mend. “That’s our secret sauce,” Reuther explained. “Because of this dynamic bond exchange, the outsole can heal itself spontaneously when we apply heat or pressure.” But it's not just about outfitting the troops with more comfortable or longer-lasting footwear. “Our goal is that you can introduce these chemical bonds to applications that pose the biggest sustainability problems, preventing them from entering landfills,” Reuther said. “We’re seeing how commercially viable this could be."
