A new type of semi-IPN gel electrolyte was prepared by using UV irradiation,and the prepolymer was synthesized via sol-gel process directly.Its chemical and physical properties were electromechanical ecnsil testing machine,characterized by FTIR spectroscopy,differential scanning calorimetry(DSC),X-ray diffractions(XRD),scanning electron microscopy(SEM),alternating current impedance(AC impedance),and linear sweep voltammetry(LSV),etc.The values of the breaking strength and elongation at break for the prepared semi-IPN gel electrolytes are 6.58 MPa and 127.2% respectively.In addition,they exhibit high ionic conductivity for the value of 2.34×10-3 S·cm-1.Also,they are electrochemically stable up to+4.6 V against Li+/Li.These make them became potential application as polymer electrolyte in devices.
