Perspectives

Anna C. Balazs

Inert surfaces can be made reactive, and active surfaces inert, by means of a thin coating of polymer. Such surface films are used in paints, plastic fabrication, corrosion resistive coatings, and medical applications. In her Perspective, Balazs discusses new results reported by Fytas et al. in the same issue (p. 2041) in which the collective motions of polymer chains anchored at a surface have been studied by a powerful optical technique: dynamic light scattering. The data provided by this technique can illuminate the link between microscopic polymer behavior and macroscopic properties of polymer coatings.
