液晶离聚物/PMMA多孔电解质膜
Study of LCI/PMMA porous electrolyte membrane
摘要
Abstract
In view of the low ion conductivity and the bad mechanical strength of the polymer electrolyte membrane, a new type of liquid crystalline ionomers (LCI)/PMMA porous polymer electrolyte membrane was made by LCI with the sulfonic acid groups, polymethyl methacrylate(PMMA) and the lithium perchlorate(LiCIO4) with the solvent method blending preparation. It adopted the sulfonic acid groups to transmit the lithium ion. The N-methyl pyrrolidone (NMP) was the plasticizer. The factor of porosity determination and the SEM indicate: the membrane is porous; the factor of porosity is 16.4%-29.3%; the aperture is in 1-9 μm. The infrared spectrum result indicates that the -OH peak of the sulfonic acid groups is 3 435 cm-1.After adding LiCIO4, -OH peak moves to 3 556 cm-1; after adding NMP, moves to 3 598 cm-1. The AC impedance result indicates: when the liquid crystal ionomers content achieves 25% at 25 Xi, it exhibits ion conductivity in the order of 2.60 x 10-6 S/cm and 3.86 x 10-3 S/cm with 20% NMP.关键词
