Fig. 2: Performance of the synthesized dielectric gels.
From: Dielectric gels with ultra-high dielectric constant, low elastic modulus, and excellent transparency
The polymer and solvent contents of the testing gels are fixed at 50 wt% each. a Stress–strain curves of dielectric gels with different cross-linker contents (molar ratios to monomer, as labeled). Each gel was stretched until rupture. b Elastic modulus (calculated from the stress–strain curves at a strain of 10%) and strain at break, plotted against the cross-linker content. c Cyclic loading of a dielectric gel (cross-linker content of 0.15%). The initial loading cycle was set to 100% strain. After the loading–unloading cycle, the sample was immediately reloaded to 300% strain for the second cycle and then 500% strain for the third cycle. d Plot of the dielectric constants versus testing frequency for the dielectric gels with PC and EC/PC solvents; the ratio represents the volume ratio. e Plot of the dielectric dissipation factor versus testing frequency for the dielectric gels with PC and EC/PC solvents. f Transmittance test of a 1-mm-thick dielectric gel in the visible range
