After a person is finished wearing a spray-on garment, it can be recycled. This is done by shredding or cutting the garment into small pieces and dissolving it in a solution. Smaller pieces of fabric dissolve more easily than big ones do, and resemble tissue dissolving in water, Torres says. The propellant used to spray the fabric is the same substance as the solvent, which simplifies the recycling process because you don’t have to have another solution or solvent on hand, Luckham says.
The team is also developing spray-on, lightweight waterproof plaster casts and testing prototypes in partnership with U.K. military personnel who have lost limbs in combat. Commercialization of a final product is expected once testing has been completed. Spray-on bandages and other medical applications are also under development. An advantage of the spray-on fabric is that it's sterile when applied, which makes it attractive for emergency applications such as field dressings, Torres says.
