The PANI-DBSA is synthesized by doped reaction of aniline and dodecylbenzenesulfonic acid (DBSA) in epoxy acrylic resin by in-situ emulsion polymerization. PANI-DBSA/EA polymer blends had been mixed with castor oil polyurethane (PU) prepolymer, crosslinking agent (e.g., styrene and acrylonitrile) at the presence of benzoyl peroxide (BPO) as initiator to form the conductive nano-PANI-DBSA/EA/PU interpenetrating networks composite film. By determining the conductivity and tensile strength, the influence of PANI-DBSA content, crosslinking agent, coupling agent and the type and amount of BPO concentration on the conductivity and mechanical properties of the composite film had been studied. The results showed that the composite film exhibited its electrical conductivity up to 2×10 -5 S/m and tensile strength 15.8 MPa when it comprised PANI-DBSA 12.5%, KH-550 3%、BPO 0.4% and styrene 60%.
