Natural Dye Cyanidin‐Based Polyacrylonitrile Conjugate as Environmental‐Friendly Thin Film Sensor

Natural Dye Cyanidin‐Based Polyacrylonitrile Conjugate as Environmental‐Friendly Thin Film Sensor Natural dye cyanidin extracted from red cabbage and adsorbed on the surface of polyacrylonitrile (PAN) in the presence of epichlorohydrin coupling agent to form transparent environmental‐friendly thin‐film sensor was achieved. The potential thin film showed successful sensor behavior and demonstrated gradual and reversible sensing change in the pH range of 2.0–11.0. Visual and Lucid color change of the thin film was observed at inclined pH value; fuchsia color at pH 1–3, purple color at pH 6–8, and blue color at pH 10–11.

Abstract

Natural dye cyanidin extracted from red cabbage and adsorbed on the surface of polyacrylonitrile (PAN) in the presence of epichlorohydrin coupling agent to form transparent environmental‐friendly thin‐film sensor was achieved. The potential thin film showed successful sensor behavior and demonstrated gradual and reversible sensing change in the pH range of 2.0–11.0. Visual and Lucid color change of the thin film was observed at inclined pH value; fuchsia color at pH 1–3, purple color at pH 6–8, and blue color at pH 10–11. Structural identification of the thin‐film sensor provided evidence of physical adsorption of cyanidin on the surface of PAN via epichlorohydrin coupling agent as prevailed by FTIR spectroscopy. Moreover, the thin‐film sensor demonstrated thermal stability up to 105°C, as onset degradation temperature, as verified by thermogravimetric analysis (TGA) and its first derivative (DTG) techniques. Moreover, the pH‐sensing change of the 1‐mm‐thick thin film was checked by UV‐Vis technique. The oligomer formation of cyanidin, mediated by epichlorohydrin, lead to the formation of stable and successful adsorption on the surface of PAN with uniform and soft appearance. The concept of the reversible stability and response time of the thin film sensor were also proved. The cyanidin‐based PAN conjugate sensor act as a novel environmental‐friendly sensor with the following specifications: low cost, easy fabrication, high sensing capacity, appropriate reversible stability, and response time specifications. Such exquisite specifications of the thin‐film sensor adapt it to put into service in optoelectronics and microelectronic devices.
