Characteristics of ionic conductivity in lithium salt onto MG30 polymer electrolyte / Nor Fazila Mahamad Yusoff
A 30% PMMA-grafted natural rubber (MG30), lithium triflouromethanesulfonate (LiCF3S03 or LiTf ) and dimethyl carbonate (DMC) as a plasticizer were dissolved in tetrahydroforan (THF) as a solvent in the preparation of the solid polymer and gel polymers electrolytes (SPEs and GPEs). The ionic conducti...

| 总结: | A 30% PMMA-grafted natural rubber (MG30), lithium triflouromethanesulfonate (LiCF3S03 or LiTf ) and dimethyl carbonate (DMC) as a plasticizer were dissolved in tetrahydroforan (THF) as a solvent in the preparation of the solid polymer and gel polymers electrolytes (SPEs and GPEs). The ionic conductivity was characterized by using Impedance Spectroscopy (IS) at room temperature. The highest of conductivity value of SPE with composition of MG30 - 35 wt% UCF3SO3 is 39.05x10"5 S cm"1 at room temperature. SPE with highest conductivity was added with different weight percent of DMC plasticizer to form a GPE. The GPE with highest conductivity is 21.24xl0"5 S cm"1 at composition of 30 wt% of DMC plasticizer at room temperature. The polymer salt complexes were investigated using Fourier - Transform Infrared (FTIR) at room temperature within the frequency range of 4000-500 cm-1. |
