a Detailed chemical structures of BA, PEGMA, [EMIm][DCA], PEGDA and TPO that are used to prepare CSN ionogels precursor solution. b–d Illustrations of the photopolymerization process during photopolymerization. b CSN ionogels precursor solution before photopolymerization. c CSN ionogels network structure after photopolymerization. d Detailed chemical structure of crosslinked CSN ionogels. e Comparison on conductivity and transmittance of the ionogels with different PEGMA contents. Scale bar in inset photographs: 1 mm. f Illustration of macroscopic phase separation resulted from photopolymerizing the pure BA ionogel (BA:PEGMA = 0). g Illustration of ionogel with no macroscopic phase separation resulted from photopolymerizing the BA-PEGMA ionogel precursor with BA:PEGMA ratio of 7:3. h Illustration of the microphase-separated structure within the BA-PEGMA ionogel. i Schematic presentation of ionic pathway along the PEGMA phase. j, k 2D SAXS scattering patterns (j) and SAXS scattering intensity variation (k) for ionogel with/without PEGMA. l SEM images for the ionogels with/without PEGMA. Scale bar: 1 µm. Data are presented as the mean values ± SD, n = 3 independent samples. Source data are provided as a Source Data file.
