Abstract

Substrates are provided for use in a heating and/or blowing device that dispenses volatile material. The substrates are a porous medium (such as porous ceramic) having their interior pores coated by a polymeric material (such as a polysiloxane). The substrate is impregnated with a volatile such as pyrethrum. The substrate is less susceptible to clogging. Also disclosed are methods of making those substrates in which the polymeric material is wicked into the substrate with a volatile solvent.

Claims (27)

1. ~A substrate impregnated with a volatile material to be dispensed from the substrate, the substrate comprising:
a substrate formed from a medium having pores and passages, and having a polymeric material coating interior surfaces of the pores and passages; and volatile material disposed in the pores;
wherein the volatile material is more volatile than the polymeric material and the polymeric material inhibits the volatile material from clogging the substrate if the substrate is heated.
2. ~The substrate of claim 1, wherein the polymeric material is a polysiloxane.
3. ~The substrate of claim 2, wherein the polysiloxane is selected from the group consisting of polyalkylsiloxanes and polyalkylarylsiloxanes.
4. ~The substrate of claim 3, wherein an alkyl group in the polysiloxane is a C1 to C10 alkyl group.
5. ~The substrate of claim 4, wherein the polysiloxane is selected from the group consisting of polydimethylsiloxane, polymethylphenylsiloxane, and polymethyloctylsiloxane.
6. ~The substrate of claim 1, wherein the polysiloxane has a molecular weight of 750 dalton or greater.
7. ~The substrate of claim 1, wherein the substrate is capable of being heated at 200°C so as to release at least 90 percent of the volatile material from the substrate.
8. ~The substrate of claim 7, wherein the substrate is capable of being heated at 200°C to release at least 95 percent of the volatile material from the substrate.
9. ~The substrate of claim 1, wherein the substrate is selected from the group consisting of wicks, mats and plugs.
10. ~The substrate of claim 1, wherein the medium is selected from the group consisting of ceramics, sand, sawdust, cellulosic materials and metals.
11. ~The substrate of claim 10, wherein the medium is a ceramic.
12. ~The substrate of claim 1, wherein if the substrate is heated to 200°C for 24 hours the polymeric material therein will not have decomposed as a result thereof.
13. ~The substrate of claim 1, wherein the polymeric material is a phenolic material.
14. ~The substrate of claim 13, wherein the phenolic material is a phenol~
formaldehyde.
15. ~The substrate of claim 1, wherein the polymeric material is a polyurethane.
16. ~The substrate of claim 1, wherein the polymeric material is a fluorocarbon polymer.
17. ~The substrate of claim 16, wherein the fluorocarbon polymer is selected from the group consisting of polytetrafluoroethylene and~
polydifluoroethylene.
18. ~The substrate of claim 1, wherein the polymeric material is less than 4% of the substrate by weight.
19. ~The substrate of claim 1, wherein the volatile material is selected from the group consisting of insecticides, insect repellants and insect growth regulators.
20. ~The substrate of claim 19, wherein the volatile material is pyrethrum and the medium is a ceramic.
21. ~The substrate of claim 19, wherein the volatile material is a terpene.
22. ~A method for forming a substrate impregnated with a volatile material, the substrate comprising:
a substrate formed from a medium having pores and passages, and having a polymeric material coating interior surfaces of the pores and passages; and a volatile material disposed in the pores;
wherein the volatile material is more volatile than the polymeric material and the polymeric material inhibits the volatile material from clogging the substrate if the substrate is heated;
the method comprising:
providing the porous medium;
dissolving the polymeric material in a volatile solvent to form a solution;
allowing the solution to wick into the pores and passages; and permitting the substrate to expel at least a portion of the volatile solvent from the substrate.
23. ~The method of claim 22, wherein the solvent is selected from the group consisting of tetrahydrofuran, dioxane, methylene chloride, chloroform, acetone, supercritical carbon dioxide and dimethylsulfoxide.
24. ~The method of claim 22, wherein the expelling of the solvent is aided by heat, negative pressure, and/or passing a gas over a surface of the substrate.
25. ~The method of claim 22, wherein the medium is a ceramic medium and the polymeric material is a polysiloxane material.
26. A method for forming a substrate impregnated with a volatile material, the substrate comprising:
a substrate formed from a medium having pores and passages, and having a polymeric material coating interior surfaces of the pores and passages; and a volatile material disposed in the pores;
wherein the volatile material is more volatile than the polymeric material and the polymeric material inhibits the volatile material from clogging the substrate if the substrate is heated;
the method comprising:
mixing a polymeric material with a second material that can form a porous medium having pores and passages; and subjecting the mixture to a process that can be used with the second material alone to form a porous medium having pores and passages.
27. The method of claim 26, wherein the polymeric material is in the form of beads.
