Dynamic scale theory for characterizing surface morphology of layer-by-layer films of poly(o-methoxyaniline)

J Nanosci Nanotechnol. 2004 May;4(5):548-52. doi: 10.1166/jnn.2004.084.

Abstract

The dynamic scale theory and fractal concepts are employed in the characterization of surface morphological properties of layer-by-layer (LBL) films from poly(o-methoxyaniline) (POMA) alternated with poly(vinyl sulfonic acid) (PVS). The fractal dimensions are found to depend on the procedures to fabricate the POMA/PVS multilayers, particularly with regard to the drying procedures. LBL films obtained via drying in ambient air show a more homogeneous surface, compared to films dried under vacuum or a flow of nitrogen, due to a uniform rearrangement of polymer molecules during solvent evaporation.
