a Digital photograph of CP-PVA organogel stretched to 10 times the original length (scale bar = 15 mm). Conductivity (b), tensile stress-strain curves (c), and performance comparison (d) of CP-PVA organogels with different contents of CP (relative to the total mass of PVA and CP) (strain rate: 200% min−1). Data in panel b are presented in box-and-whisker plots, where the central dots, lines, and box limits indicate the mean, the median, and the upper/lower quartiles, and the whiskers extend to 1.5× the interquartile range from the quartiles (sample size = 4). e, f Ashby plots comparing the toughness, strain, and conductivity of CP-PVA organogels with previously reported hydrogels. Data points are obtained from references mentioned in Supplementary Fig. 10 and Supplementary Table 3. g Schematic illustration showing the balance between miscibility and self-aggregability of polymers. Temperature-dependent FT-IR spectra (h), Raman spectra (i), and ordinary FT-IR spectra (j) of different organogels. k AFM characterizations of p-CP-PVA and CP-PVA organogels: height image (left panel), phase image (middle panel), and tunneling current image recorded in TUNA (tunneling AFM) mode (right panel) (scale bar = 500 nm). Data in panels d, h-j were presented as mean values ± standard deviation (mean ± s.d.) (sample size = 4). Statistical significance was assessed using two-sided t-tests for comparisons between two groups (b, i), and one-way analysis of variance (ANOVA) for comparisons among multiple groups (panel j), with significance determined by p values. Unless otherwise specified, CP-PVA organogels with a solid content of ~50 wt% (relative to the total mass of organogels) and CP’s content of 22 wt% (relative to the total mass of CP and PVA) were used here.
