The effect of the shear flow on the thickness change of a polyelectrolyte membrane grafted onto a glass substrate was directly investigated with a flow cell combined with a confocal laser scanning microscope. The membrane thickness decreased proportionally to an increase in the shear stress of the flow when the shear rate exceeded a critical value of 1 s-1. The higher the ionic strength was of the fluid, the greater the thinning effect was. The correlation between the critical shear rate and...[Show more]
