Extensive transport and modeling studies have been performed on a series of polymers based on vinylbenzyltrimethylamonium cations. Flouride is used as a non-reactive surrogate for hydroxide to increase the computational efficiency of transport calculations that can be performed. Interesting effects of water and residual chloride in the film have been explained. In ordered di-block polymers we have strong theoretical evidence for narrow water domains that facilitate rapid transport of anions. With this model we will be able to predict diblock polymer structures that require less water for efficient anion transport. In addition to these studies we are discovering new base stable polymer backbones and cations. A large part of this effort is dedicated to discovering new methods for the production of robust thin anion exchange membranes.
