Fig.S1 Solution viscosity of the spinning solution as a function of the PCS
concentration, implying the solution viscosity is proportional to the PCS
concentration. Thus the solution viscosity can be expressed by a more intuitionistic
parameter, PCS concentration.

concentration of (a) 0.85 g ml-1 and (b) 0.95 g ml-1.
Fig. S3. The TPD-MS profiles of cured PCS fibers: (a) survey profile at the
temperature of 50~1600 °C and (b) closer view in the temperature range of
1000~1600 °C. The inset in (a) is the magnified image in the range of 500~900 °C;
the inset in (b) is the magnified image for m/z: 2 H2, m/z: 16 CH4, m/z: 30 C2H6 and
m/z: 44 CO2.
