| Abstract Scope |
Polymer based sensors have significant advantages over other competitive remote, long-gauge sensing technologies based on their remarkable electromechanical behavior and excellent reinforcement properties. The need for passive sensors to monitor temperature variance has been critical in many packaging applications. In this study, temperature sensing patches are prepared using Polyaniline (PANI) doped with a protonating agent on substrates for support. This simple system is dependent on doped PANI exhibiting strong thermochromic response in the UV−vis−NIR spectra (440 nm) at around 280 K (6.85 °C). This temperature range makes it ideal for cold transport applications, especially, food and biologics transport. The role of conformational changes in the polymer chain along with the potential role of dopants, optimal device structure and further application in industry are discussed. |
