Fig. 2

a Schematic illustration of Pre T-ECH, T-ECH, and Pure ECH. T-ECH has a double network structure of template polymer (PAA) and PEDOT:PSS. Pre T-ECH lacks PEDOT:PSS network while Pure ECH lacks a template network. b Stress-strain curves of T-ECH, Pre T-ECH, and Pure T-ECH (Strain rate = 50%/min). Mechanical properties of T-ECH are modified by changing the amount of crosslinker (MBAA) and PEDOT:PSS content (Supplementary Table 1). c Stress-strain curves of T-ECH with various PEDOT:PSS contents and crosslinking concentrations. d Images of compressed PAA and T-ECH with 60 kPa (20 N) and 120 kPa (35 N), respectively. e Compressive stress-strain curves of T-ECH, Pre T-ECH, and PAA (Strain rate = 0.2%/min) f Graph comparing electrical conductivities (and toughness of Pre T-ECH, T-ECH, and Pure ECH. The data plotted represents the mean and standard deviation (n = 5 for conductivity, n = 3 for toughness, n means number of independent experiment). g Electrical resistance change of T-ECH under strain (Strain rate = 200%/min).
