Hazardous particle binder, coagulant and re-aerosolization inhibitor
View Patent ↗A copolymer and water/ethanol solvent solution capable of binding with airborne contaminants or potential airborne contaminants, such as biological weapon agents or toxic particulates, coagulating as the solvent evaporates, and adhering the contaminants to a surface so as to inhibit the re-suspension of such contaminants. The solution uses a water or ethanol/water mixture for the solvent, and a copolymer having one of several functional group sets so as to have physical and chemical characteristics of high adhesion, low viscosity, low surface tension, negative electrostatic charge, substantially neutral pH, and a low pKa. Use of the copolymer solution prevents re-aerosolization and transport of unwanted, reactive species thus increasing health and safety for personnel charged with decontamination of contaminated buildings and areas.
1. A method of inhibiting re-aerosolization and transport of aerosol and aerosolizable particles, comprising:
applying a copolymer solution to said particles, said copolymer solution comprising: a solvent selected from the group consisting of water, and ethanol and water mixture; and a copolymer dissolved in said solvent so that said copolymer solution has low viscosity of less than 50 cps and low surface tension of less than 60 dynes/cm,
for coagulating aerosol and aerosolizable particles when applied thereon and adhering said particles to a surface.
2. The method of claim 1 ,
wherein the solution is applied as an aerosol.
3. The method of claim 1 ,
wherein the solution is applied as a spray.
4. The method of claim 1 ,
wherein the solution is applied as a coating.
5. The method of claim 1 ,
wherein the solution is applied to suspended aerosol particles.
6. The method of claim 1 ,
wherein the solution is applied to a surface having aerosolizable particles thereon.
7. The method of claim 1 ,
wherein said solvent is about 1:2 ethanol to water mixture.
8. The method of claim 1 ,
wherein said copolymer solution additionally has a negative electrostatic charge.
9. The method of claim 8 ,
wherein said copolymer solution additionally has a substantially neutral pH, and low pKa of less than 7.
10. The method of claim 9 ,
wherein said copolymer has a set of functional groups comprising OAm, AA-AMP, and BAEMA.
11. The method of claim 1 ,
wherein said copolymer solution further comprises at least one additive dissolved in the solvent, said additive being at least one of decontamination agent, inhibitor, and fluorescent agent.
