摘要：

The interface roughness correlation in diblock copolymer brushes synthesized by atom transfer radical polymerization was studied. The interfaces of diblock copolymer brushes can be correlated over a wide range of thicknesses. The existence of the correlation is not an artifact of deposition history, and that weakening the segregation at the internal interface by swelling with a nonselective good solvent weakens the interface correlation. The correlation is found for thicknesses much higher than those for which correlation is seen in small molecule liquids.
