Rapid Decontamination of Chemical Warfare Agent Simulant with Thermally Activated Porous Polymer Foams
Abstract
Highly porous poly(dicyclopentadiene) (pDCPD) foam was synthesized via ring opening metathesis polymerization and high internal phase emulsion (HIPE) templating. Alkane and alkene moieties within the pDCPD foam oxidized slowly in air to form carbonyl, peroxy, and hydroxyl groups. Heating pDCPD to 85 degrees C in air accelerated the oxidation of pDCPD, producing reactive peroxy species at reduced time scales, compared to oxidation at room temperature. The oxidized pDCPD foams rapidly sequestered and decontaminated the toxic chemical warfare agent simulant, demeton-S via oxidation to vinyl, sulfoxide, and sulfone oxidation products. In addition, the porosity and high surface area of the pDCPD) HIPE foams likely assists in the sequestration of demeton-S via capillary interaction. Collectively, these data demonstrate a new and highly tunable class of polymer materials capable of simultaneous sequestration and decontamination of toxic chemicals.
