Abstract

A non-detonable source of at least one of an explosive or explosive vapor is disclosed, as well as a method of preparing the explosive or explosive vapor that includes the step of mixing the explosive with at least 50% inert material which retains the explosive vapor until heat is applied.

Claims (16)

1. A method of preparing a non-detonable explosive vapor source comprising the steps of:

providing a polymer; and

encapsulating a non-detonable vapor of an explosive using said polymer to provide a non-detonatable matrix, wherein said polymer comprises at least 50% of the non-detonatable matrix, and wherein the encapsulating polymer is a microcapsule including a discrete polymer shell that surrounds a core explosive material.

2. The method of claim 1 , wherein the core explosive material includes a predetermined amount of the explosive.

3. The method of claim 1 , wherein the microcapsule comprises a predetermined amount of a vapor signature of the explosive.

4. The method of claim 1 , wherein the microcapsule encases the explosive in a shell of plastic.

5. The method of claim 4 , wherein the plastic comprises any of polystyrenepolystyrene (PS), polysulfone (PSt), polyethylmethacrylate (PEM), poly(lactic-co-glycolic acid) (PLGA), polycarbonate (PC), polyetherimide (PEI), poly (vinyl butyral-co-vinyl alcohol-co-vinyl acetate) (PVBV AV A), or polyethylmethacrylate (PEM).

6. The method of claim 1 , wherein the explosive comprises any of triacetone triperoxide (TATP), trinitrotoluene (TNT), Diacetone diperoxide (DADP), hexamethylene triperoxide diamine (HMTD), or naphthalene.

7. A method of preparing a non-detonable explosive vapor source comprising the steps of:

providing a polymer; and

encapsulating a non-detonable vapor of an explosive using said polymer to provide a non-detonatable matrix, wherein said polymer comprises at least 50% of the non-detonatable matrix, and wherein the encapsulating polymer is a microcapsule that encapsulates a microsphere-like matrix of polymer and core explosive material.

8. The method of claim 7 , wherein the core explosive material includes a predetermined amount of the explosive.

9. The method of claim 7 , wherein the microcapsule comprises a predetermined amount of a vapor signature of the explosive.

10. The method of claim 7 , wherein the microcapsule encases the explosive in a shell of plastic.

11. The method of claim 10 , wherein the plastic comprises any of polystyrenepolystyrene (PS), polysulfone (PSt), polyethylmethacrylate (PEM), poly(lactic-co-glycolic acid) (PLGA), polycarbonate (PC), polyetherimide (PEI), poly (vinyl butyral-co-vinyl alcohol-co-vinyl acetate) (PVBV AV A), or polyethylmethacrylate (PEM).

12. The method of claim 7 , wherein the explosive comprises any of triacetone triperoxide (TATP), trinitrotoluene (TNT), Diacetone diperoxide (DADP), hexamethylene triperoxide diamine (HMTD), or naphthalene.
