Abstract (en)
[origin: WO2013147934A1] Colorimetric moisture-indicating sensors comprising a solid polymeric support and a bis(glyoxime)-transition metal complex bound to the solid polymeric support are described. The solid polymeric support is a strong acid cation exchange resin. These colorimetric moisture-indicating compositions and sensors can be used to detect moisture. In some embodiments, detecting moisture comprises the sequential steps of (1) providing a colorimetric moisture-indicating sensor comprising a solid polymeric support and a bis(glyoxime)-transition metal complex bound to the support, and (2) exposing the composition to a moist atmosphere. A method of making a colorimetric moisture-indicating sensor comprising the sequential steps of (1) adsorbing transition metal ions onto a solid polymeric support, and (2) complexing a bis(glyoxime) to the adsorbed transition metal ions is also provided.
