Conductive rubber composite of SIS/LPB/PAn

The PAn (polyaniline) was synthesized within the crosslinked SIS (styrene-isoprene-styrene)/LPB (liquid polybutadiene) rubber matrix by the in-site polymerization to form the mono-face conductive rubber complex. The effects of the crosslinking degree of the polymer matrix, the amount of aniline and the oxidant, and the polymerization time on the conducting properties of the complex were experimentally studied. It has been shown that the conductivity of the complex decreases with the increase of crosslinking degree of the matrix, increases with the amount of aniline, and increases first and then decreases with the increase of amount of the oxidant.
