Abstract

A barrier article and a method of making and using the barrier article are provided. The barrier article includes a base layer; an adhesive layer supported on a first surface of the support layer; and a barrier layer supported on a second surface of the support layer, opposite the adhesive layer.

Claims

1. A barrier article, comprising:

a base layer;

an adhesive layer supported on a first surface of the support layer; and

a barrier layer supported on a second surface of the support layer, opposite the adhesive layer.

2. The article as defined in claim 1, wherein the base layer comprises one or more of polymer, metal, ceramic, or glass.

3. The article as defined in claim 2, wherein the polymer comprises one or more of polyacrylamide, polyacrylate, polyamide, polycarbonate, epoxy, polyester, polyether, ionomer, polyimide, polyolefin, polystyrene, polyurethane, polyvinyl, silicone, polysiloxane, or norbornene polymer.

4. The article as defined in claim 1, wherein the base layer comprises reinforcement comprising one or more of metal, glass or polymer.

5. The article as defined in claim 1, wherein the adhesive layer comprises one or more of a pressure sensitive adhesive, a structural adhesive, a hot melt adhesive, or a curable adhesive.

6. The article as defined in claim 5, wherein the adhesive layer comprises one or more of acrylate, amide, acrylonitrile, carbonate, cyanate ester, cyanurate, ethylene-vinyl acetate, epoxy, fluoroplastic, ionomer, methyl methacrylate, non-ethylenic olefin polymer (linear or branched), nylon, olefin, polyester, styrene, styrene-maleic anhydride, sulfone, styrene-acrylonitrile, or urethane.

7. The article as defined in claim 1, wherein the adhesive layer comprises reinforcement.

8. The article as defined in claim 1, wherein the barrier layer comprises one or more of polymer, metal, ceramic, or glass.

9. The article as defined in claim 1, wherein the barrier layer comprises a barrier structure that is configured to cut or puncture contacting skin, cloth, or both.

10. The article as defined in claim 1, wherein the barrier layer comprises a barrier structure that is configured as a pin, a needle, a blade, a hook, a barb, or a combination of two or more thereof.

11. The article as defined in claim 1, wherein the barrier layer comprises a frangible barrier structure having an inner surface that defines a volume, and the volume is filled with an ampoule load.

12. The article as defined in claim 11, wherein the ampoule load comprises one or more of an adhesive;

incapacitating agent;

lacrymator;
