Fig. 1 Operation mechanism and scanning electron microscopy images of MTC device. Operation mechanism and scanning electron microscopy images of MTC device. (A) Solubility graph at different temperature for sodium acetate anhydrous (CH3COONa, red line) and sodium acetate trihydrate (CH3COONa·3H2O, black line) where the solid lines indicate a saturated state. Insets show the digital pictures of MTC glass for various phase conditions. The right graph shows the general process of MTC, which is composed of the mechanochromic process and the thermochromic process. (B) The microscopic surface morphology of sodium acetate crystal with (i) low- and (ii) high-magnification scanning electron microscopy (SEM) images. The red dotted box exhibits the boundary of the crystal and the yellow dotted box shows the surface, which has an irregular vertically stacked structure. Hyunmin Cho et al.
