A new technology to coat fabric in self-healing, thin films may one day lead to chemically protective suits that may prevent farmers from exposure to pesticides, soldiers from chemical or biological attacks.
Melik Demirel, Professor at Pennsylvania State University talks about the new innovation in textile technology with new enzyme incorporated coating.
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.
Polyelectrolyte coatings are made up of positively and negatively charged polymers.During the layering, enzymes can be incorporated into the coating.
The researchers used urease – the enzyme that breaks urea into ammonia and carbon dioxide – but in commercial use, the coating would be tailored with enzymes matched to the chemical being targeted.
