摘要：

(Chemical Equation Presented) Polymer brushwork: The collapse of polyelectrolyte brushes in salt solutions combined with binding interactions and ion-size-exclusion effects is used in the design of smart polymer surfaces that can be switched between permanently collapsed or extended states with different surface properties (see picture) - a step toward the use of surface-confined polyelectrolytes as nanoactuators. © 2005 Wiley-VCH Verlag GmbH & Co.
