| 摘 要： | 分别将钠基蒙脱土(Na-MMT)和有机改性蒙脱土(OMMT)引入到聚氧化乙烯-聚硅氧烷(PEO-PDMS)聚合物电解质体系中,通过溶液浇铸法制备得到新型蒙脱土复合聚合物电解质材料.适量加入蒙脱土,可有效降低聚合物体系的结晶度,提高聚合物电解质的电导率,室温下样品Na-MMT-6%电导率达到2.24×10-5 S/cm.同时,蒙脱土质量分数的增高还有利于聚合物电解质体系的热稳定性及力学性能的提高.此外,由于有机改性蒙脱土片层间距较钠基蒙脱土大,因此相同添加量下,二者对聚合物电解质的材料性能的影响存在差异.

| Abstract: | PEO-PDMS based composite polymer electrolytes were prepared by introducing sodium montmorillonite or organic montmorillonite into the polymer electrolyte system, using the solution-cast technique. The adding of a proper content of montmorillonite reduced the crystallinity of the polymer electrolyte, which is benefit for the ionic conductivity. The ionic conductivity of the sample Na-MMT-6% reached 2.24×10-5 S/cm at room temperature. Meanwhile, the increasing of montmorillonite content also profits the thermal stability and mechanical property. In addition, there exist differences on the performance of polymer electrolyte while adding Na-MMT or OMMT as the same content, because the layer distance of OMMT is larger than that of Na-MMT. |
