a The transparent MEG2-Li. b Tensile tests for MEG1-Li, MEG2-Li, MEG3-Li. c Stretch (λ) plotted against molar ratios of MMA/EGA. d, True tensile stress-strain curves of MEG2-Li. e The photograph of MEG2-Li lifting a 1.5 kg bucket after 15,000% stretch. f Stress-strain cycling tests of MEG2-Li at the rate of 10 mm/min, the interval of each cycle was 60 min. g The statistics of Young’s modulus for each cycle in Fig. 3f, error bars represent standard deviation. h, The photograph of further laterally stretching the MEG2-Li with already 30,000% stretch.
