The reactants met at the gel interface, and the redox reaction between them produced a polyaniline (PANI) interlayer, a PANI membrane, at first. The electrons abstracted from the aniline molecules in the gel during the oxidation are transferred through a conducting PANI membrane to oxidant molecules in the external solution. The reaction between aniline and peroxydisulfate thus takes place without the need for the reactant molecules to physically meet. PANI, therefore, grows from the interface into the gelatin gel. When the loci of reactants are reversed, i.e. the oxidant is inside the gelatin gel and aniline hydrochloride in the surrounding solution, PANI grows from the gel interface into the aniline solution but some PANI is produced inside the gelatin gel, too.
