Palladium-containing polymers as hybrid sensory materials (water-soluble polymers, films and smart textiles) for the colorimetric detection of cyanide in aqueous and gas phases

[Display omitted] •Film-shaped solid sensory membranes and sensory polymer-coated fibers allowed the preparation of manageable solid sensory kits.•Colorimetric sensory polymers had palladium in their structure.•Sensory polymers enabled the detection of cyanide in both aqueous and gas phases. We have prepared solid sensory materials for the visual detection of cyanide in 100% water solutions and gas phases. The materials are hybrid polymers that were prepared from a palladium-containing acrylic monomer for use as sensory films and smart textiles.
