Abstract

Abstract: Polymer indicators are autonomous responsive materials that provide an optical signal of a specific exposure in time. This review describes the different polymer systems utilized to obtain indicators based on structural color. Structural color originates from the interaction of light with a periodic nanostructured polymer which causes a specific wavelength to be reflected. This reflected light can be used for fabricating battery‐free indicators that show visible structural color changes upon exposure to a stimulus or analyte. In this review, the typical structural color response types categorized by stimulus are discussed and compared. Furthermore, the steps toward possible applications of optical indicators based on structural colored polymers are outlined. Abstract : Optical indicators are autonomous responsive materials that provide an optical indication of a specific exposure history. This review describes the different polymer systems utilized to obtain a photonic response based on structural color. The response types are discussed and compared, which allows for an extensive comparison of methods applied in the broad field of responsive photonic polymers.
