Abstract

Density profiles of a perdeuterated poly(methyl methacrylate) (dPMMA) film spin-coated on a substrate in water (H₂O) and deuterated water (D₂O) were examined along the direction normal to the interface by specular neutron reflectivity (NR). Although H₂O and D₂O were typical non-solvents for dPMMA, their interfaces were more diffuse than the air/dPMMA interface due to the swelling caused by the sorption of H ₂O and D₂O molecules. An isotopic effect on aggregation structure of the dPMMA film in water was also discussed.
