Transport mechanism of aromatic vapor through silver salt carrier/polymer blend membrane and its humidity effect

The transport mechanism, electrical conductivity, water uptake and benzene vapor transports of silver-containing solid-type carrier membranes have been studied. AgBF4/Nafion blend membrane and silver form Nafion membrane are used as models for the salt/polymer blend membrane and ion-exchange type membrane. Results indicated that ionic carriers in the AgBF4/Nafion blend membrane are mobile at low humidity. The AgBF4/Nafion's water uptake is low similar to an ion-exchange Nafion membrane. The membrane selects benzene over cyclohexane at low humidity.
