Composite polymer electrolytes (CPEs) were prepared by containing blend of poly(ethylene oxide) (PEO) and poly(methyl methacrylate) (PMMA) as a host polymer, propylene carbonate as a plasticizer, and LiClO4 as a salt. By an addition of a various content of ionic liquid attached TiO2 (IL-TiO2) to above electrolytes, the effects were studied. As a result, by increasing the IL-TiO2 content, the crystallinity of PEO was decreased and the ionic conductivity was increased. The ionic conductivity of CPEs was dependent on the content of IL-TiO2 and showed the highest value of 1.05 x 10(-4) S/cm at 9 wt.%. However, when IL-TiO2 content exceeds 9 wt.%, the ionic conductivity was decreased due to the slow ionic transport due to immiscibility or aggregation of the IL-TiO2 filler within the polymer film matrix.
复合聚合物电解质（CPEs）是通过将聚环氧乙烷（PEO）和聚甲基丙烯酸甲酯（PMMA）的共混物作为主体聚合物、碳酸丙烯酯作为增塑剂以及高氯酸锂作为盐来制备的。通过向上述电解质中添加不同含量的离子液体负载二氧化钛（IL-TiO₂），研究了其效果。结果表明，随着IL-TiO₂含量的增加，PEO的结晶度降低，离子电导率增加。CPEs的离子电导率取决于IL-TiO₂的含量，在9 wt.%时显示出最高值1.05×10⁻⁴ S/cm。然而，当IL-TiO₂含量超过9 wt.%时，由于聚合物薄膜基质中IL-TiO₂填料的不混溶或聚集导致离子传输缓慢，离子电导率降低。
