UNIVERSITY PARK, Pa. — Someday, chemically protective suits made of fabric coated in self-healing, thin films may prevent farmers from exposure to organophosphate pesticides, soldiers from chemical or biological attacks in the field and factory workers from accidental releases of toxic materials, according to a team of researchers.
“Fashion designers use natural fibers made of proteins like wool or silk that are expensive and they are not self-healing,” said Melik C. Demire l, professor of engineering science and mechanics. “We were looking for a way to make fabrics self-healing using conventional textiles. So we came up with this coating technology.”
The procedure is simple. The material to be coated is dipped in a series of liquids to create layers of material to form a self-healing, polyelectrolyte layer-by-layer coating.
