“…The PDA/AgNP-embedded CMC film (prepared with 30 mg/L AgNPs) changed from purplish-blue to purple and purple to reddish- purple as the temperature increased. At the highest temperature, PDA mobility increased and it change color faster than at lower temperatures [ 5 ]. The PDA without AgNPs presented a slower color change than PDA with AgNPs because the PDA interacts with the surface of AgNPs [ 28 ].…”

“…Glycerol decreased the mobility of PDA at various temperatures ( Figure 3 b). Moreover, glycerol exhibits a symmetrical chemical structure that leads to decreased core-shell structure of PDA/AgNPs in CMC films [ 5 ]. Figure 4 shows the color change of each film.…”

“…Subsequently, PDA vesicles may change color from blue to red with environmental stimuli such as temperature. Above 60°C, side-chain strain is relieved, a phenomenon that allows PDA to move and form stable structures and subsequently change color from blue to red [ 5 , 6 ].…”

“…Furthermore, adding plasticizers such as PEG-400, glycerol, xylitol, and sorbitol can improve the temperature sensitivity of PDA. Recent examples of new colorimetric TTIs are plasticized PDA/SiO 2 films, which change from purple to red within 4 days when stored below 35 °C [ 5 ]. The polymeric bilayers of PCDA show a reversible color transition when anchored on ZnO nanoparticles (ZnONPs) and an irreversible transition when PCDA forms vesicles.…”

Time–temperature indicators (TTIs) can be important tools in product applications to monitor food quality losses, especially for fruits and vegetables. In this context, the effects of silver nanoparticles (AgNPs) and glycerol on the color change of polydiacetylene/AgNPs (PDA/AgNPs) embedded in carboxymethyl cellulose (CMC) film as time–temperature indicators (TTIs) were investigated. A CMC film prepared with 30 mg/L AgNPs and a 1:3 (v/v) PDA:AgNP ratio exhibited a faster color change than under other conditions. At 35 °C, the films with PDA/AgNPs changed color from purplish-blue to purple and purple to reddish-purple over time due to the higher thermal conductivity of AgNPs and larger PDA surface area exposed to specific temperatures. The total color difference (TCD) of PDA/AgNP-embedded CMC film directly changed with regard to time and temperature. However, adding glycerol to the system resulted in a symmetrical chemical structure, a factor that delayed the color change. Scanning electron micrographs showed AgNPs embedded in the CMC films. Transmission electron micrographs indicated a core-shell structure of PDA/AgNP vesicles in the CMC matrix. PDA/AgNP vesicles were confirmed by second derivative Fourier transform infrared spectroscopy, with a new peak at 1390–1150 cm−1. The kinetics of TTIs from PDA/AgNP-embedded CMC films yielded an activation energy of 58.70 kJ/mol.

“…Therefore, the head group modification or metal oxide composites of PDA assemblies are alternative approach to enhance colorimetric sensing sensitivity, selectivity and response time. Recently, some research groups have modified PDA's sensing properties by adding zinc oxide (ZnO) [5], silicon oxide [6] and zirconium oxide [7].…”

Formaldehyde is a toxic pollutant that harmful effect on human health. This work focus on the development of a colorimetric sensor to detect formaldehyde solution using composites of polydiacetylene (PDA), thiol-functionalized polydiacetylene (PDA-SH) and zinc oxide (ZnO) nanosheets. The as-prepared PDA/PDA-SH/ZnO vesicles exhibit a blue color, and change to a red color in the presence of formaldehyde solution. With increasing formaldehyde concentrations, the optical absorption spectra show the decreasing of absorption intensity at 640 nm wavelength, and new absorption peak occurred at 540 nm wavelength with increasing its intensity. Additionally, the PDA/PDA-SH/ZnO sensor exhibit high selective to formaldehyde and its color transition is easily observed by the naked-eye. These results indicate a possibility to use PDA/PDA-SH/ZnO sensor for on-site monitoring formaldehyde in an environment.
