Yield:-
Reaction Conditions:
with polymethylmethacrylate (PMMA) in N,N-dimethyl-formamide at 80 - 900;Inert atmosphere;
Steps:
PAN (Sigma-Aldrich) and PMMA (Aladdin) were respectively dissolved in N, N-dimethylformamide (DMF, Aldrich) by stirring at 80°C for 24h in concentrations of 8 and 16wt.%, which were used as the outer and inner solutions for coaxial electrospinning. The fibrous webs were stabilized by a thermal treatment in an air atmosphere oven at 250°C for 1h with a heating rate of 5°C/min in order to convert PAN from thermo plastic to non-plastic compound, which is critical to obtain dimensional stability and, hence, a fibrous morphology [20]. The stabilized fibrous webs were subsequently carbonized at 900°C for 1h with a heating of 5°C/min in a nitrogen atmosphere furnace, forming MhMpCFs with the elimination of PMMA.
