Chameleon fibers change color, hue, depth of shade, or optical transparency in the presence of an electrical or magnetic field. Markets for such fibers-which incorporate molecules and oligomers that change their absorption or reflection of electromagnetic radiation in the infrared, visible, and ultraviolet spectra-include floor coverings, wall covering, billboards, biosensors, detectors, and military and consumer apparel. Photoadaptive fibers undergo illumination induced reversible optical and heat reflectivity changes. Derivation from polymeric films involves crosslinking polyvinyl alcohol with dimethylsulfoxide in the presence of polyacrylic acid. Intelligent fibers manufactured from stimuli sensitive oligomers respond to changes in pH, temperature, and electrolytes. The include thermal responsive hygrogels, amphophilic polymers, and shape memory polymers.
