The phase angle also changed from 90º for PES-GO (capacitative behavior) to 0º for RGO coated fabrics (resistive behavior). In general an increase in the number of RGO layers produced an increase of the conductivity of the fabrics. EIS measurements in metal/sample/electrolyte configuration showed better electrocatalytic properties and faster diffusion rate for RGO specimens. Scanning electrochemical microscopy was employed to test the electroactivity of the different fabrics obtained.The sample coated with GO was not conductive since negative feedback was obtained.When GO was reduced to RGO the sample behaved like a conducting material since positive feedback was obtained. Approach curves indicated that the redox mediator had influence on the electrochemical response. The Fe(CN) 6 3-/4-redox mediator produced a higher electrochemical response than Ru(NH 3 ) 6 3+/2+ one.

“…Shortly after sometime, chemical vapour deposition (CVD) was used as a viable alternative [16,17]. However, it was soon realised that these procedures offer a low production yield and particularly in the case of micromechanical cleavage they were time consuming that hindered effective and full-exploitation of these materials [18]. Even though researches have fine-tuned the technique to provide high quality crystallites up to 100 µm in size, making it better separated ( Fig.…”

“…GO can be exfoliated by sonication in water but the resulting material is electrically insulating, so it should be reduced to restore its conductivity. Reduction can be performed by chemical or thermal treatment [18]. Rapid heating has also been reported as a possible solution resulting in high yields of dispersed carbon powder with a few percent of carbon flakes [42].…”

Graphene has achieved a great amount of popularity and interest from the science world because of its extraordinary physical, mechanical and thermal properties. Graphene is an allotrope of carbon, having one-atom-thick planar sheets of sp 2 bonded carbon atoms densely packed in a honeycomb crystal lattice. Many methods to synthesize graphene have been developed over a short period and we believe it is necessary to create a list of the most notable approaches. This article focuses on the methods to synthesize graphene in an attempt to summarize and document advancements in the synthesis of graphene research and future prospects.

“…Also, charge/discharge cycling of the battery is dependent on several factors, some of which includes; solubility of the active materials in solution resulting to decrease in capacity, side reactions and/or instabilities of anions formed, structural modification during the charge/discharge leading to capacity loss on cycling. Finally, low conductivity of organic materials is also a limiting factor and this should be addressed by using conductive additive materials such as carbon nanotubes [44] and graphene [45,46] in order to improve electron transport within the electrode.…”

The quest for green and sustainable energy storage systems has brought about the need for a material system that can satisfy the following requirements; low cost of production, environmental benignity, flexibility, redox stability, renewability and structural diversity. Interestingly, organic compounds of carbonyl functionality have been identified as potential candidates to proffer solutions to the abovementioned challenges. This review therefore discusses various classes of carbonyl compounds as active components in some rechargeable batteries, highlighting their major strengths and drawbacks.
