Figure 1. Chemical, thermal and transport characterization of supported QSPEs: (A) ¹H NMR spectra of the three QSPEs in DMSO, together with the ¹H NMR spectra of ethylene carbonate (EC), and methylethylketone (MEK); (B) FTIR spectra of QSPE-2, processed in acetone and MEK, between 400 and 2,000 cm^-1; (C) thermogravimetric profiles, collected under Ar atmosphere, at a heating rate of 10 °C min^-1, between room temperature and 1,000 °C; (D) Derivative TGA profiles, up to 600 °C; (E) DSC profiles, collected at a heating rate of 2 °C min^-1, between -80 and 100 °C (cycle 2); (F) Ionic conductivity vs. temperature, between 20 and 80 °C (average of three cells).
