The polyurushiol (PUS)/multiwalled carbon nanotube (MWCNT) composite coatings were prepared by in situ composite method. The fracture morphology of the composite films showed that MWCNTs had been well dispersed in PUS matrix, which significantly decreased the electrical resistivity and the gloss of the composite films. The nonconducting/conducting state transition took place at approximately 3.0 wt% of MWCNTs with the volume electrical resistivity of 10 4 Ω cm. The results of the mechanical tests revealed that the impact of strength and the storage modulus of the coatings increased with the addition of MWCNTs. Furthermore, the PUS/MWCNTs composite films had good chemical resistance. POLYM. COMPOS., 2012. © 2012 Society of Plastics Engineers
