Abstract
|
We report on a thin polyelectrolyte film (mixed polyelectrolyte brush) with a gradual change of thecomposition (ratio between two different oppositely charged surface-grafted weak polyelectrolytes) acrossthe sample. The gradient of surface composition creates a gradient in surface charge density and,consequently, a gradient of the wetting behavior. The gradient film is sensitive to a pH signal and canbe reversibly switched via pH change.
