摘要: The threat of chemical warfare agents (CWA) compels research into novel self-decontaminating materials (SDM) for the continued safety first-responders, civilians, and active service personnel. capacity to actively detoxify, as opposed merely sequester, offending under typical environmental conditions defines added value SDMs in comparison traditional adsorptive materials. Porous polymers, synthesized via high internal phase emulsion (HIPE) templating, provide a facile fabrication method with permeable open cellular structures that may serve air filtration applications. PolyHIPEs comprising polydicyclopentadiene (polyDCPD) networks form stable hydroperoxide species following activation ambient conditions. hydroperoxide-containing polyDCPD react quickly CWA simulants, Demeton-S 2-chloroethyl ethyl sulfide, forming oxidation products confirmed gas chromatography mass spectrometry. simplicity detoxification chemistry paired porous foam factor presents an exciting opportunity development filter media.
