    Metal-organic framework doped reduced graphene oxide and polyaniline composite electrodes for supercapacitor

  • Original language description

    Recently, carbon-based materials such as graphene oxide or reduced graphene oxide (rGO) had been widely investigated as electrodes for supercapacitors {Ses) owing to their good electrical properties. However, drawbacks of carbon-based materials such as low specific area and hord to fabricate had hindered their applications. ln order to solve these problems, researchers had concentrated on the composite materials which should combine the advantages of their components. Recently, polyaniline (PANI) have been acquired great attention as one of the potential materials for ses application because of their good pseudo-capacitive performance as well as facile synthesis and low cest. However, PANI exhibited poor cycling stability through chargedischarge processes over long periods of time which restrain its application in Ses. ln this study hybrid nanomaterial based on rGO and PANI will be prepared and electrochemical storage capacity will be enhanced by metal-organic framework (MOF). Since being introduced, the crystalline porous MOFs, in which metal ions and clusters are linked by organic units had required intensive attention from scientists. MOF materials exhibited high surface area, high stability, large pere volume and organic functionality which led to their potential application in electrochemical devices. Moreover, the availability of various kinds of metal ions and organic linkers has provided thousands of choice for MOF with many potential applications. The composite of rGO and PANI in this study will be conducted via in situ polymerization following by doping of MOF on this structure. The electrochemical properties of these composites will be studied via cyclic voltammetry (eV) and galvanostatic charge-discharge test to identity the effects of conductive polymers to the materials electrochemical properties.
