Figure 2. (A) Binding energies of DAH/Am-DAH monomers with Li⁺, SN, and TFSI^-; (B-D) FTIR spectra of p(DAH-co-Am-DAH), p(DAH) and SN. DAH: Bis[2-(acryloyloxy)ethyl] heptanedioate; Am-DAH: bis[2-(acrylamido)ethyl] heptanedioate; SN: succinonitrile; TFSI^-: bis(trifluoromethanesulphonyl)imide anions; FTIR: Fourier transform infrared.
