Abstract
Graphene oxide (GO) is a promising material with excellent properties. The GO has an aromatic lattice sheets of graphene with multi oxygen functional groups, such as ketone, carboxyl, and carbonyl groups. The addition of these groups is resulting from an oxidation treatment of the graphene. Go has the ability to exfoliate in many solvents and disperse in the water. Hummers method is an improved way to synthesize the GO because no toxic gas forms in yield. It is a reversible material, so the graphite can be restored from the GO within electrochemical reduction. The advantage of the GO gives it the chance to take a part of various applications. The electrical and the mechanical are the main fields for the GO. Many groups made films and nanofibers of GO by using a combination of GO with other substances like, solvents or polymers to enhance the viscosity of the GO1. The aim of this work is to form the GO nanofibers from it owns film, which means self-assembly of the GO nanofibers. Furthermore, the GO which been used is pure. Two different techniques have been followed to overcome the viscosity issue of the GO. Electrospinning for the GO solution preformed as the first method. In this method the potential difference between the syringe and the collector causing an electric filed to draw the solution and form the fibers. The second method was vacuum filtration where the vacuum is used to absorb all the liquids and leave the GO over the filter to get fibers. These GO thin films can be used in plethora or applications such as energy storage, water and like solution filtration, oil and water separations and many more.
