摘要
提出并实施了利用纳米金刚石平台乳液合成 Nafion® 型共聚物的新方法。与不含金刚石的类似物相比，用金刚石（4.1% wt.）制成的聚合物凝结物提高了共聚物的离子容量。凝固膜的 SEM 扫描模式显示出迷宫式结构，钻石与共聚物融为一体，没有任何偏析。这种结构为氢燃料电池新型膜提供了必要的弹性和强度特性。同步加速器实验显示，新型膜具有离子通道网络，可确保质子传导性比使用预制成分生产的类似膜高出一个数量级。
Proton-conducting membranes based on Nafion® synthesized by using nanodiamond platform
New method of emulsion synthesis of Nafion®-type copolymer composition by using nanodiamond platform has been proposed and implemented. Produced polymeric coagulate saturated with diamonds (4.1 % wt.) possessed increased ionic capacity of the copolymer comparative to the analogue without diamonds. SEM patterns for coagulate membranes showed labyrinthine structures with diamonds integrated into copolymer without any segregation. This structuring provided necessary elastic and strength properties of new type membranes for hydrogen fuel cells. In new membranes synchrotron experiments exhibited a network of ionic channels which ensured a proton conductivity by one order of magnitude higher than that for the analogue produced of premade components.
