Mechanical and electrical properties of the pyroprotein-based fibres as a function of the heat-treatment temperature. a Tensile strength and b Young’s modulus of the pyroprotein-derived fibre samples treated at different temperatures with axial stretching, estimated by a mechanical tester for a single fibre (n = 10 for each group). The error bars denote standard deviations of the mean. c Photograph of the SSF1200 bundle enduring 0.5 kg of loading weight. d V–I curves of the pyroprotein-derived fibres for various HTTs and (inset) the conductivity obtained from the inverse slope of V–I curves as a function of the HTT
