    • note
    • It is important for the blend to be weakly immiscible; otherwise, phase separation occurs rapidly, and coupling between spin-casting and solvent-drying phase separation process leads to complex patterns.

    • note
    • We refer to separate measurements on PS/PVME blend films containing silica nanoparticles having polystyrene grafted on their surface to make the particles soluble in the blend and to avoid adsorption of the particles on the silicon substrate. The phase separation of these filled blend films appeared to be very similar to the blend without the filler.

    • Certain commercial materials and instruments are identified in this article to adequately specify the experimental procedure. In no case does such identification imply recommendation or endorsement by the National Institute of Standards and Technology; nor does it imply that materials or equipment identified are necessarily the best available for the purpose.

    • We interpret the tendency of PS to enrich the silica beads to arise from the specific chemistry of the Stöber process used to synthesize the silica beads.

    • note
    • Preliminary measurements on phase separation with approximately 20 nm silica beads with grafted PS chains as filler particles in a phase separating PS/PVME blend do not show an appreciable perturbation of the filler on the phase separating morphology. These measurements correspond to a shallow quench, however, and different results are anticipated for very deep quench phase separation studies.

    • c is its critical point value so that ∈ is small for temperatures far from the critical point and for high molecular weight blends (see ref 19).
