Abstract

A novel water-based polyurethane (WPU)/polyaniline (PANI) composite coating with high electrical conductivity was fabricated by in-situ polymerization in this paper. The conductive PANI doped with dodecyl benzenesulfonic acid (DBSA) was synthesized from aniline salt through in-situ polymerization in a well-dispersed aqueous solution of WPU. The morphology of composite films, particles size and the electrical conductivity with the effect of different amount of PANI (varies from 1 to 7 wt%) were discussed. The results indicate that, the electrical conductivity of the WPU/PANI film increases with the increasing of the PANI content. Meanwhile, due to the formation of hydrogen bonds between –NH of PANI and –C=O of WPU, the stability and mechanical properties of the composites have been improved. The composite coatings with excellent conductivity have offered a pathway for the different applications in antistatic, electrostatic discharge (ESD), and electromagnetic interference (EMI) shielding materials.
