Polymer/dye composition as component for interactive paper used as photochemical or electrosensors

摘要

The purpose of this article is to discuss one comparatively simple way for modification of papers, on which can be developed many new and attractive sensor systems. Variation of the sensitivity of the papers toward different kind of radiation, temperature, electricity, toxic chemicals can be developed on the base of polymer/dye systems. The active part of the high sensitive papers doped with the composition is the polymer/dye system. The result of the interaction - change of color can be produced on the surface or into the paper by the scheme: a/ action plus polymer yields polymer product plus dye yields polymer/dye product. The polymer is active part in the process. b/ action plus dye yields dye product. The polymer is inactive part of the composition.
