Magnetic field (MF) and the mass ratio of a co-surfactant and a surfactant (K(m)-m(n-butanol)/m(SDBS)) on effects the phase behavior, conductivity, and micro-emulsification of the microemulsion system during aniline polymerization were investigated by a pseudo-ternary phase diagram of sodium dodecyl benzene sulfonate (SDBS)/n-butanol/aniline/H(2)O. Our results show that with an increase in alcohol content, the area of the microemulsion region increased initially and then decreased. This area reached a maximum at a K(m) of 1.0 and increased under the influence of a MF Characterization of the pseudo-ternary phase diagram was undertaken by an analysis of the solution conductivity as the water content varied in the presence of a ME Transmission electron microscopy (TEM) indicated the particle-size of the polyaniline (PAn), which polymerized in the presence of the MF, was much smaller than that of the PAn polymerized in the absence of the MF.
