a Temperature-variable IR spectra of P(BA-co-MAA0.05) ionogel upon heating from 20 to 200 °C (interval: 10 °C). b 2DCOS synchronous and asynchronous spectra generated from (a). In 2DCOS spectra, red colors represent positive intensities, while blue colors represent negative intensities. c 2D low-field 1H NMR spectra at 20, 100, and 200 °C, respectively. d AFM phase image of the ionogel at 20 °C. e Temperature-dependent T1/T2 ratios of PBA-rich matrix and PMAA-rich nanophase, respectively. f Temperature-variable SAXS profiles. g Temperature-dependent SAXS intensity changes at q = 0.06 and 0.5 nm−1, respectively.
