Abstract
We report studies of the self-assembly of amphiphilic diblock copolymers, p olystyrene-b-poly(alkyl acrylate) at the air water interface. Using the Lan gmuir film balance, unusual multiple plateau/inflection transitions in surf ace pressure / molecular area isotherms have been observed. Transmission el ectron microscopy of the corresponding Langmuir-Blodgett films has shown th e presence of surface micelles. We have studied the effect of a range of di fferent alkyl blocks on the isotherms. Possible mechanisms for the multiple inflections observed in the isotherms are discussed.
