CHARACTERIZATION OF LOW-TEMPERATURE SOLUBLE POLYANILINE

Because the charging of polyaniline films occurs in the bulk of the ma terial rather than exclusively at the polymer-electrolyte interface, t he use of thick polymer films for battery applications is justifiable. Here, we present a method for producing soluble polyaniline which can be cast to form free-standing films. Investigation by scanning electr on microsopy (SEM) has shown that these films are significantly more c ompact than those made by standard electropolymerization.
