a SAXS profile plots of DSE-0~3 that demonstrates the presence of microphase separation on the order of 1–3.7 nm. b AFM phase images of DSE-0~3. The dark areas represent the soft phase and the bright areas represent the hard phase, indicative of the microphase separation structure of DSE-0~3. c Transmittance of DSE-0~3 in the visible range. Insert: photogragh of the as-synthesized DSE, suggesting the high transparency of DSE. d DSC traces of DSE-0~3. The constant Tg at around −76 °C is displayed. e Time-temperature superposition (TTS) rheology of DSE-0~3. Master curves were built using time-temperature superposition (TTS). Frequency sweeps were performed at 0.1–100 Hz, temperature sweeps were run from 30 °C to 170 °C (30 °C as the reference temperature), and the strain automatically modulated at 5% ± 2% by the instrument to make sure the measured torque at a reasonable value as the sample softened.
