Carbon, an element of prehistoric discovery, is very widely distributed in nature. It is found in abundance in the sun, stars, comets, and atmospheres of most planets. Carbon in the form of microscopic diamonds is found in some meteorites.

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.
