Morphological Evolution of Self-Assembled Polyaniline Nanostuctures Obtained …

The chemical oxidation of polyaniline is carried out at constant acidity, investigating six separate pH levels (pH = 1, 2, 3, 4, 5, and 6). All prior studies on polyaniline self-assembly used a falling-pH or a temporarily buffered falling-pH method, making this the first application of pH-stat techniques to the study of polymer nanostructure formation. This allows us to isolate with improved…
