Fig. 1: Synthesis and optical, mechanical, and electrical properties of the PAAc–DES gels with different hydrogen bond donors.

a Chemical structure of the monomer, crosslinker, initiator, salt, and four hydrogen bond donors. b UV–Vis spectrum of the four PAAc–DES gels. c Tensile stress–strain curves of the four PAAc–DES gels. d Nyquist plots and e ionic conductivity of the four PAAc–DES gels. Values in panel e represent the mean and standard deviation (n = 3). The standard deviations for PAAc–ChCl–Gly, PAAc–ChCl–Urea, and PAAc–ChCl–DG gels are not shown in the graph because they are negligible.
