Ion Exchange Capacity of Nafion and Nafion Composites - Langmuir, 16, p.2866-2871, 2000 .

The ion exchange capacity of recast Nafion films and composites of Nafion and polystyrene microbeads is determined by titration. Composite formation enhances exchange capacity; exchange capacity increases with the surface area of microbeads in the composite. For recast films, an equivalent weight of 996 ( 24 is found, whereas the lowest equivalent weight (highest exchange capacity)found for a composite is 878 ( 8. This suggests that J13
