Abstract
A flexible reversible color change poly-(10,12-tricosadiynoic acid) TCDA-ZnO (2.5wt%) composite based chromatic sensor was successfully designed and fabricated by inkjet printing. Fabricated sensors showed good reversibility and stable chromatic properties with color transition temperature at 70°C. Attenuated Total Reflection (ATR) – Fourier Transform Infrared (FTIR) spectra show chelate formation between TCDA and ZnO. Temperature-dependent Raman spectra indicate that the blue-red phase of poly-TCDA-ZnO (2.5wt%) is thermally triggered at 70°C and the amorphous phase is formed near 120°C. An inkjet printed Quick Response (QR) code using poly TCDA-ZnO demonstrates a sensory functionality which can be incorporated in these codes.
