  The present application provides a composite material that comprises a solid and solid-supported non-polymeric switchable moiety, wherein the switchable moiety comprises a functional group that is switchable between a first form and a second form, said first form being neutral and hydrophobic, and said second form being ionized and hydrophilic. The composite material converts to, or is maintained in, said second form when the switchable moiety is exposed to CO 2 at amounts sufficient to maintain the ionized form. The composite material converts to, or is maintained in, said first form when CO 2 is removed or reduced to an amount insufficient to maintain the ionized form. CO 2 is removed or reduced by exposing the composite material to heat and/or a flushing inert gas such as N 2 , Ar, or air. Envisioned uses of these composite materials includes removing water from non-aqueous solvents, removing water vapour from gaseous mixtures, and cleaning industrial reaction vessels and/or pipelines.

  本申请提供了一种复合材料，其包括固体和固体支持的非聚合物可开关基团，其中，可开关基团包括一种功能基团，该功能基团可在第一形态和第二形态之间切换，所述第一形态为中性和疏水的，所述第二形态为离子化和亲水的。当可开关基团暴露于足以维持离子化形态的CO2量时，复合材料转化为或维持在第二形态。当 被去除或减少到不足以维持离子化形态时，复合材料转化为或维持在第一形态。通过将复合材料暴露于热和/或冲洗惰性气体（如N2、Ar或空气）中，可以去除或减少 。这些复合材料的预期用途包括从非水溶剂中去除水，从气态混合物中去除水蒸气，以及清洁工业反应器和/或管道。
