A microwave deposition technique for silanes, previously described for production of oleophobic fabrics, is adapted to provide a fabric support material that can be subsequently treated by dip coating. Dip coating with a sol preparation provides a supported porous layer on the fabric. In this case, the porous layer is a porphyrin functionalized sorbent system based on a powdered material that has been demonstrated previously for the capture and conversion of phosgene. A representative coating is applied to cotton fabric at a loading level of 10 mg/g. This coating has minimal impact on water vapor transport through the fabric (93% of the support fabric rate) while significantly reducing transport of 2-chloroethyl ethyl sulfide (CEES) through the material (7% of support fabric rate). The described approaches are suitable for use with other fabrics providing amine and hydroxyl groups for modification and can be used in combination with other sol preparations to produce varying functionality.
一种先前用于生产疏油织物的硅烷微波沉积技术，经过改进后可提供一种织物支撑材料，该材料随后可通过浸涂进行处理。用溶胶制剂进行浸涂可在织物上形成支撑多孔层。在这种情况下，多孔层是基于一种粉末材料的卟啉功能化吸附剂体系，该粉末材料先前已被证明可用于光气的捕获和转化。以10 mg/g的负载量将代表性涂层施加到棉织物上。该涂层对水蒸气透过织物的影响最小（为支撑织物速率的93%），同时显著降低了2-氯乙基乙基硫醚（CEES）透过该材料的速率（为支撑织物速率的7%）。所描述的方法适用于其他具有可用于改性的胺基和羟基的织物，并且可与其他溶胶制剂结合使用以产生不同的功能。
