Does Water Swell The Ordered Domains In polyelectrolyte/clay Multilayers?
Abstract
X-ray diffraction has been used to study the sorption of water by multilayer films containing ordered stacksof alternating layersof an organic polyelectrolyte and individual plateletsof a smectite. The position and shape of the 001 reflections due to the ordered polyelectrolyte/platelet stacks were essentially the same when in air at low relative humidity (23-25% RH) and under water. These data indicate that swelling occurs exclusively in X-ray amorphous regions within the film, and that the ordered polyelectrolyte/clay domains themselves are not ‘swellable’ by water.
