Hydroxide exchange membranes functional groups

PAES has been functionalized with quaternary guanidinium groups for use in polymeric hydroxide exchange membranes. The quaternized polymers could be synthesized by the chloromethylation of PAES, followed by the reaction with pentamethyl-guanidine, c.f.. Figure 7.15 [113]. [Pg.193]

Alkaline-based polymer electrolyte membranes are relative newcomers on the scene. It has been widely believed that the quaternary ammonium hydroxide functional group (RN4 , OH ), which is the one used in most anion exchange membranes, is self-destructive, because the OH- ion is likely to attack the RN4 cation. In addition, the specific conductivity of an OH conducting ionomer was suspected of being at least a factor 3-A lower than that of the H" conducting... [Pg.451]
