Fig. 3: Adhesion and electrical properties regulation of cocrystal ionogels.

a 90° peel images of sample PIL₁₈/IL₁₈-20% at 40 °C and 20 °C. Unless otherwise specified, the adhesion substrate used in experiments was stainless steel, and the peel speed was 50 mm/min. b Displacement-peeling strength curves and c plateau peeling strength of cocrystal gel with different IL contents at 40 °C and 20 °C. Effects of (d) peeling speed and e substrate on the peeling strength of cocrystal gel, with IL content fixed at 20%. f Reusability of cocrystal gel. g Ionic conductivity of cocrystal gel with different IL contents at 40 °C and 20 °C. h Relationship between ionic conductivity and temperature of cocrystal gel, with IL content fixed at 20%. i Schematic diagram of the cocrystal effect restricting ion movement. Impedance response of PIL₁₈/IL₁₈-20% cocrystal gel during the j heating-melting process and k cooling-crystallization process, tested at a frequency of 1 kHz. The electrodes used for the test were 15 μm-thick aluminum foil with dimensions of 2 × 2 cm. Data (c–f) are presented as the mean values ± SD, n = 3 independent samples. Source data are provided as a source data file.
