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.
