Non-classical interfacial polymerization has been recently focused on due to the alternative process benefiting the control of material structure and properties. By applying two non-classical interfacial polymerization methods, e.g. one with asymmetrical bi-phase volumes and another with varied interface area size, several polyanilines, PANIs, were prepared and characterized. Results showed that the increase of the bottom oil phase volume can allow the dopant dispersion uniformly to benefit the PANI doping, and the reduction of the top aqueous phase volume can reduce the distance to benefit the PANI formed at the interface to fast diffuse into and stabilize in the upper phase. Results further showed that the reduction of the interface area is similarly to the increase of the bottom phase volume positively for PANI formation. The increase of the bottom phase volume or reduce the interface area both can enhance the crystallinity and conductivity for PANI.
