ABSTRACT:
Catalytic enzyme-modified textiles are disclosed for providing protection from chemical exposure. The textiles are composed of a cloth substrate, at least one polyelectrolyte layer, at least one enzyme layer to degrade the chemical agent, and at least one capping layer. Also disclosed is the related method for making catalytic enzyme-modified textiles.
