Protective suit and methods of manufacture thereof

摘要

The present disclosure is directed to a composite material comprising one or more layers that are able to bind and deactivate chemical and/or biological agents. The first layer comprises a porous polymer substrate and a nucleophilic organic polymer cross-linked on the surface or within the pores of the porous polymer substrate using a carbamate cross-linking agent, wherein the cross-linked nucleophilic polymer comprises functional groups operative to form a covalent bond with a chemical or biological agent. The composite material is used to manufacture items of protective apparel including chemical-biological protective suits.
