Abstract
Diblock copolymers confined to a two-dimensional surface may produce uniform features of macromolecular dimensions (10 − 100 nm). We present a mathematical model for nanoscale pattern
formation in such polymers which captures the dynamic evolution of a solution of poly(styrene)-
b-poly(ethylene oxide), PS-b-PEO, in solvent at an air-water interface. The model has no fitting
parameters and incorporates the effects of surface tension gradients, entanglement or vitrification,
and diffusion. The resultant morphologies are quantitatively compared with experimental data.
