摘要：
This paper examines the effect of the substrate on the morphology of organic films, using glass plates modified by the adsorption of monomolecular films. The geometrical flatness of vacuum-deposited polystyrene film increases with increasing surface free energy of the substrate. On the other hand, uniform deposition of hexatriacontane occurs on the substrate with a surface free energy of around 30 mN m-1, but the film is textured on polar substrates with higher surface energies. Autophobicity and/or the Stranski-Krastanov model can explain the growth of textured hexatriacontane film on such surfaces.
