Investigation of Carbon Nano structures Prepared by Thermolysis of Poly Acrylamide

Carbon nano structures have been synthesized by thermal annealing of Poly (acryl amidosulfonic acid) gel. Poly (acryl amidosulfonic 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 degree C, 350 degree C, and 460 degree C which leads to the formation of carbon nano structures. X-ray investigation of the products implied the formation of carbon nano structures with average size of 4 ± 1 nm. Conclusions showed that proceeding after the mentioned steps of gel treatment at 250 degree C, 350 degree C, and 460 degree 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
