Micro-porous poly(methyl methacrylate)-grafted polyethylene membrane for Li battery separator |
| 초록 |
Abstract Micro-porous poly(methyl methacrylate)-grafted polyethylene (PE-g-PMMA) membrane was prepared by radiation grafting of methyl methacrylate onto a polyethylene separator, followed by phase inversion process. The micro-porous PE-g-PMMA membrane was characterized by AC impedance analyzer, thermal analyzer, and mercury porosimeter. The micro-porous PE-g-PMMA membrane showed the improved thermal and electrochemical properties compared with original PE separator. The ionic conductivity of the prepared membrane with 262 wt% of grafting degree was measured to be 1.27 mS/cm at room temperature. |
