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.548-552engdynamic scale theorylayer-by-layer filmspoly(o-methoxyaniline)fractal dimensionmolecular controlDynamic scale theory for characterizing surface morphology of layer-by-layer films of poly(o-methoxyaniline)Artigo10.1166/jnn.2004.084WOS:000224106800011Acesso restrito
