Effects of crosslinking agent for PVA base membrane
Abstract
Currently, electrochemical devices is widely used as power sources in portable consumer electronic devices. However, these electrochemical devices which composed of liquid electrolyte has a limited lifespan with environmental issues. Thereby, solid polymer electrolyte, (SPE) is promising candidate to replace conventional liquid electrolyte due to that improved conductivity, more stable and reduce risk of leakage. This study was conducted to investigate crosslinking effects on Polyvinyl Alcohol based membrane in order to make a high performance Solid Polymer Electrolyte. So, different polymer such as of poly (vinyl alcohol) (PVA), poly ethylene glycol (PEG), with additives such as graphene (G), and graphene oxide (GO) were chemically crosslinked using glutaraldehyde (GA). Electrochemical Impedance Spectroscopy (EIS), Fourier Transform Infrared Spectroscopy (FTIR), and Differential Scanning Calorimetry (DSC) were used for each step to characterize the PVA/PEG/G/GO membrane. According to this study, the conductivity of PVA base membrane was increased 2 times after adding crosslinking agent. In summary, from data taken it can be finalizing that crosslinked PVA and PEG have bright potential to produce high performance Solid Polymer Electrolyte.
