In this paper, ultraviolet (UV) radiated grafting technique was introduced to the modifying of lithium-ion battery separator, and methyl methacrylate (MMA) grafted polyethylene separators were prepared through this technique to improve the affinity between the separator and liquid electrolyte, and thus improve the battery performance. Bulk photografting process was conducted, while solution grafting processes in petroleum ether, ethanol, acetone, and butyl acylate were conducted for comparison as well, the grafting degree could reach 49%. Infrared spectroscopy results showed that MMA could be efficiently grafted by UV radiation. Influence of photosensitizer concentration and radiation time was disscussed, and the morphology was observed in this paper as well.
