From sem of the polymer , we can found that , the polymer containing no dbp made by solvent of nmp had more and large pores than solvent of dmac , so it had larger liquid uptake and higher ionic conductivity 从sem测试图上也可以看出,不含dbp时,溶剂为nmp条件下制备的聚合物膜孔径比溶剂为dmac时大,孔隙多,吸液率大,离子电导率高。
Due to its excellently chemical and thermal stability , mechanical properties and nearly pure oxygen ionic conductivity , yttria - stabilized zirconia ( ysz ) has been actively investigated and applied in widely technical fields 钇稳定的氧化锆( ysz ) ,由于其特别优异的化学及热稳定性、力学性能,和几乎纯的氧离子导电性,而被广泛研究和应用。

Some results were obtained that adulterating zirconia with yttria , viz . yttria - stabilized zirconia ( ysz ) , has some oxygen ion vacancies , sequentially has ionic conductivity . and the influence on ysz ion conductivity of the different adulterated concentration of yttria was discussed 以溶胶-凝胶( sol - gel )理论为基础,制备钇稳定立方相二氧化锆( ysz )溶胶-凝胶膜,并对不同的药品配比进行测试与比较。
Solvents of dmac and nmp were used to prepare polymer electrolyte membrane , when the ratio of dbp and solvent was 20 % , both of the ionic conductivity can arrive at 10 - 3 s ? cm - 1 , and the ionic conductivity of polymer made by nmp was 35 % higher than by dmac 分别用溶剂dmac及nmp制备了聚合物电解质膜,在增塑剂与溶剂体积比为20 %时,聚合物膜的离子电导率均能达到10 - 3s ? cm - 1 ,且以nmp为溶剂的聚合物膜的电导率比以dmac为溶剂的电导率高出大约35 % 。
The liquid uptake of polymer electrolyte membrane first increase , then remaining the same as the increasing of ratio of solvents . mechanism capability and ionic conductivity fist increase then decrease during the process , but it changed not much in total . through the test of sem it can be found that the structure of membrane changed little during the process 在增塑剂含量及聚合物基质含量一定的条件下,随溶剂含量的增大,聚合物膜的吸液率先增大后基本保持不变,机械强度及离子电导率则先增大后减小,通过sem测试可知,膜的表面形貌无明显变化。
