a Stress–strain curves of the resulting S8 copolymers with various disulfide monomers. b A summary of mechanical performances of the S8 copolymers. Measurements were carried out in triplicate (n = 3); error bars show the standard deviation of the replicate measurements, the error bar centers are the means of the replicate measurements. c Radar map showing the effect of side chain functional group on the mechanical performance. d Stress–strain curves of poly(S8/TAA = 1/2) before and after self-healing at room temperature after 12 h. RT room temperature. e Optical microscopy image (left) and photograph during tensile test of poly(S8/TAH = 1/3) filament. The scale bar is 50 μm. f Stress–strain curves of poly(S8/TAH = 1/3) filament. g A summary of mechanical performances of poly(S8/TAH) filament with different amounts of TAH monomer. Measurements were repeated with at least five independent samples, error bars show the standard deviation of the replicate measurements, the error bar centers are the means of the replicate measurements. σ: maximum strength, ε: temsile strain, T: toughness, E: Young’s modulus.
