Polyurethane prepolymers were prepared from poly (carbonate diol), isophrone diisocyanate and dimethylol propionic acid. Then, aniline terminated waterborne polyurethane dispersion (ATPUD) was synthesized by capping the NCO group of the prepolymer with aniline monomer. Subsequently, ATPUD and waterborne polyurethane dispersion (PUD), respectively, were blended with conducting polymer, poly (3,4-ethylenedioxythiophene)/polystyrene sulfonate [PEDOT/PSS], to yield antistatic coating solutions, and the mixture was coated on the polycarbonate substrates. At adequate addition amounts of PEDOT/PSS less than or equal to 2.5 g, the surface resistances (1.0×1011~2.5×108 Ω/cm2) of coating films from ATPUD showed better electronic conductivities than those (5.0×1011~6.3×109 Ω/cm2) from PUD. However, at excess amount of PEDOT/PSS of 3.0 g, the surface resistance from ATPUD showed similar electronic conductivity with that from PUD.
