Polymeric Temperature Sensors
This chapter describes polymeric temperature sensors based on the combination of solvatochromic dyes and thermoresponsive polymers, which undergo temperature-induced phase transitions in solution. The concepts and synthesis of such polymeric sensors will be explained, followed by a discussion on how polymer structures influence the sensory properties. Moreover, the working mechanisms to translate the polymer phase transition into an absorbance or fluorescence output signal for different types of dyes will be discussed. Finally, selected potential applications of these polymeric temperature sensors will be highlighted.
