Investigation of carbon nanostructures prepared by thermolysis of poly acrylamide

Abstract EN

Carbon nanostructures have been synthesized by thermal annealing of Poly (acrylamidosulfonic acid) gel.

Poly (acrylamidosulfonic acid) gel had been prepared using the technique of chain polymerization utilizing acrylamide and ammonium persulphate.

Differential thermal analysis and thermo gravimetric analysis were performed on the gel.

Results showed the occurrence of three important conversions at 250 o C, 350 o C, and 460 o C which leads to the formation of carbon nanostructures.

Xray investigation of the products implied the formation of carbon nanostructures with average size of 4 ± 1 nm.

Conclusions showed that proceeding after the mentioned steps of gel treatment at 250 o C, 350 o C, and 460 o C is necessary to obtain narrower crystal size distribution.

Morphology obtained by scanning electron microscopy (SEM) explained the ability of the prepared material to adsorb ions from aqueous solution.

The SEM Results showed average particle size of the formed fine particles as 150 nm, while X-ray diffraction showed that the crystal size is of about 4 ± 1 nm.
