Abstract
A material for protection against chemical pollutants is produced by spraying onto a base fabric a mixture of activated carbon and a polymer binder to produce an open-pored foam structure which does not materially reduce the air permeability. The binder is permeable to the pollutant so the latter can reach the carbon, and the binder is less than 20% of the coating.
