TI  - Surface versus confinement induced morphology transition in triblock copolymer 
      films: a grazing incidence small angle neutron scattering investigation.

AB  - The internal nanostructure resulting from microphase separation in triblock 
      copolymer films of 
      polyparamethylstyrene-block-polystyrene-block-polyparamethylstyrene, 
      P(pMS-b-Sd8-b-pMS), has been investigated with grazing incidence small angle 
      neutron scattering (GISANS). X-ray reflectivity, grazing incidence small-angle 
      X-ray scattering (GISAXS), optical microscopy and atomic force microscopy (AFM) 
      complement the investigation. The influence of two limiting interfaces present in 
      confinement is compared to the presence of only one surface. GISANS allows for 
      the detection of structures in the very limited sample volume of confined films 
      as well as for a depth sensitivity to probe the near free surface part of bulk 
      films. With respect to the surface a perpendicular oriented lamella is observed. 
      In contrast to the shrinkage of the characteristic lamellar spacing in 
      confinement at the free surface, a slight increase is determined.
