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

空气活化的自污染聚二环戊二烯PolyHIPE泡沫用于化学战剂的快速去污

化学战剂（CWA）的威胁迫使人们对新型自净化材料（SDM）进行研究，以确保急救人员，平民和现役人员的持续安全。与传统的吸附材料相比，在典型的环境条件下，主动解毒的能力（而不是隔离螯合剂）决定了SDM的附加值。通过高内相乳液（HIPE）模板合成的多孔聚合物为具有可渗透开孔结构的材料提供了一种简便的制造方法，该材料可用于空气过滤应用。包含聚二环戊二烯（polyDCPD）网络的PolyHIPE在环境条件下在空气中活化后会形成稳定的氢过氧化物。含氢过氧化物的polyDCPD材料可与CWA模拟物快速反应，Demeton-S和2-氯乙基乙基硫醚形成氧化产物，经气相色谱质谱法确认。排毒化学的简单性与多孔泡沫形状因素相结合，为开发自净化过滤介质提供了令人兴奋的机会。
