GO is in fact a single graphite layer containing oxygen based functional groups like hydroxyl and epoxy. These functional groups are formed as a result of oxidation of G. GO is a precursor for G. The main research activities on GO and G dates back to about 2004. This area of research is gaining importance as tirro goes on. GO and G enjoy electrical conductivity, heat conductivity, heat resistance and high mechanical strength. The applications of G and GO include battries, plastics, opto- electronics, traarent coatings, solar cells, monitors, wind turbines, tooth implant, supercapacitors and chemical gas sensors. Literature review shows no report on PAN nano fibers being incorporated with GO as aprecursor for activated carbon nano fibers. Considering the properties of activated carbon nanofibers, production of ACNF containing GO and carring out investigation on their proper ties can be of invaluable interest. In this project, GO was first synthesized through Hummer’s process. The average size of the sphere shaped GO nanoparticles was shown to be around 128 nm, according to DLS analysis. To electrospin PAN nanofibers incorporated with GO nanoparticles, suspensions of GO nanoparticles with different concentrations in PAN solution of DMF were prepared by prob and bath sonication. As the electrospun nanofibers prepared from probe sonicated suspens showed thiner and more regular morphology, the probe sonicated suspensions were 108 used for the rest of the research. Following electrospinning, the spun nanofibers were activated. After activation only PAN nanofibers (average ?? =128 nm) could keep their original fibrous form, whereas GO nanoparticles containing 40% w/w GO in the precursor (average ?? =128 nm). The fibers form of other samples was changed into a network or nearly a film. FESEM micrograph of 40% w/w GO showed regular particles of GO formed on the surface of ACNFs. XRD patherns showed no considerable change in the microstructure of ACNF as a result of incorporating GO nanoparticles. FTIR analysis as well as Raman analysis proved the conversion of GO in G during the activation process. The findings of this research could be of value in Electrochemical Sensor applications.
