a The viscosity-shear rate relationship of N-R12-C solution at various concentrations from 5 to 150 mg/ml. b Shear-thinning behavior of N-R12-C solution at a concentration of 50 mg/ml with the result fitted by the Carreau model. c Simulated shear stress distributed along the channel to show the difference in each section. d Comparison of shear stress s in section C when changing the negative pressure from −60 to −90 kPa. e The value of shear stress estimated in sections A, B and C under different negative pressures. f The β-sheet contents of N-R12-C fiber under specific shear stress estimated from the corresponding negative pressure. The red line shows the fitting result by using the quadratic function. Data are presented as mean values ± SD; n = 3. Source data are provided as a Source Data file.
