Morphology of MC/KOH/PEG/graphene.

Solid polymer electrolyte (SPE) has been emerging in the high-performance and have played important roles for the past few years and are promising materials for electrochemical devices applications. Methylcellulose was chosen as a primary host as it conducts relatively low conductivity besides biodegradable, environmentally friendly and essential commercial cellulose that has been used in many industrial applications. This study is conducted to investigate the morphology of membrane using Methylcellulose (MC) as host, doping with potassium hydroxide (KOH), polyethylene glycol (PEG) as plasticizer and graphene. The properties of MC with the additive on the structure and performances of the membrane was studied. The obtained membrane was prepared via the casting technique method and was characterized by scanning electron microscopy (SEM) and X-ray Diffraction (XRD). XRD pattern shows the crystalline structure shifted to amorphous nature of polymer electrolyte (PE) when adding the PEG onto the membrane. The presence of PE has potential application in electrochemical devices based on the results obtained. [ABSTRACT FROM AUTHOR]
