An interpenetrating polymer network (IPN) is a chemical or physical cross-linking of two polymer networks and the IPN structure allows for reinforcing mechanical properties and improving electrochemical properties of gel polymer electrolytes. We prepare poly(ethylene glycol)-epoxy based IPN electrolytes by in-situ sequential thermal and photo crosslinking methods to simultaneously enhance their mechanical and electrochemical properties. Their electrochemical properties, mechanical properties, glass transition temperature, surface morphology, and atomic composition are investigated using electrochemical impedance spectroscopy, rheometer, differential scanning calorimetry, and field emission scanning electron microscope. In this research, the curing process of PEG and epoxy polymer networks and their affinity will also be explored. |
