Abstract: G/MoS₂/Ekonol/PES/PPS multiple composite coatings was prepared by the dip coating method. The components of different coatings of G/MoS₂/Ekonol/PES/PPS complex-coating have been optimized by blending regression experiment based on the evaluation criterion of the bonding strength of the coatings. The bonding strength is determined by the pull-off test, and the bonding surface of the composite coatings has been studied. The effects of the coating components, preparing parameters of he coatings and coating thickness on the bonding strength of coatings are studied. Resultsshow that it is possible to prepare G/MoS₂/Ekonol/PES/PPS composite coatings with good mechanical properties by the dip coating method. A larger bonding strength can be obtained by using the typital formula: Ekonol: PES: PPS: G/MoS₂: additives=25:20:45:8:2.
