Abstract: The present application provides switchable, homogeneous paint composition and methods of painting and/or forming films or coatings using the composition. The composition includes a liquid having an aqueous solution and dissolved acid gas (e.g., carbonated water), and a switchable polymer. The switchable polymer converts from a protonated, water-soluble form in the liquid to a water-insoluble unprotonated form following removal or substantial removal of the liquid and acid gas.

Abstract: 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 CO2 at amounts sufficient to maintain the ionized form. The composite material converts to, or is maintained in, said first form when CO2 is removed or reduced to an amount insufficient to maintain the ionized form. CO2 is removed or reduced by exposing the composite material to heat and/or a flushing inert gas such as N2, 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.

Abstract translation: 本申请提供了一种复合材料，其包含固体和固体支持的非聚合物可切换部分，其中可切换部分包括可在第一形式和第二形式之间切换的官能团，所述第一形式是中性和疏水性的，以及 所述第二形式被离子化和亲水化。 当可切换部分以足以维持电离形式的量暴露于CO 2时，复合材料转化为或保持在所述第二形式中。 当将CO 2除去或减少到不足以维持电离形式的量时，复合材料转化为或保持在所述第一形式中。 通过将复合材料暴露于加热和/或冲洗惰性气体如N 2，Ar或空气来除去或减少CO 2。 这些复合材料的设想用途包括从非水溶剂中除去水分，从气体混合物中除去水蒸气，以及清洁工业反应容器和/或管道。
