Disclosed herein are multi-layer structures comprising a first composite layer disposed over a second composite layer, wherein the first composite layer contains a first active material dispersed in a first polymer containing an elastomeric polymer and the second composite layer contains a second polymer which may have a second active material dispersed therein, wherein the first active material chemically or physically interacts with at least one toxic chemical and is selected from the group consisting of metal-organic frameworks (MOFs), metal oxides, metal hydroxides, zeolites, and combinations thereof, and wherein the active material and the second active material (if present) are the same as or different from each other, and the first polymer and second polymer are the same as or different from each other, subject to the proviso that the first composite layer and the second composite layer compositionally differ from each other in at least one respect.
