Fabrication of current collector using a composite of polylactic acid and carbon nano-material for metal-free supercapacitors with graphene oxide separators and microwave exfoliated graphite oxide electrodes

摘要

AbstractThe method of fused deposition modelling has been applied for the preparation of a current collector from a composite of polylactic acid and carbon nano-material. The current collectors are investigated employing IR and Raman spectroscopy. A metal-free supercapacitor has been built on the base of microwave exfoliated graphene oxide electrodes, utilising a graphene oxide membrane as a separator and the current collectors from the polymer-nano-carbon composite. Electrochemical investigations (galvanostatic charge-discharge and cyclic voltammetry at various scan rates) have been performed on the supercapacitor.Highlights?Metal-free supercapacitors (SCs) were built.?Сurrent collectors were created from polymer composite of carbon nano-materials.?Microwave exfoliated graphene oxide (MEGO) was utilised as electrode material.?Graphene oxide (GO) membranes were employed as separators of SCs.?Performance of the SC with GO separator exceeds in capacity as against the one with the Nafion separator.]]>
