Abstract
The rheological properties of acrylic paints and polyaniline (PAni) blends, with different contents of PAni doped by dodecyl benzene sulphonic acid (DBSA) and, dispersed by mechanical stirrer and ultrasonic, were investigated by controlled shear rate testing ramps. The results showed that the commercial acrylic paint had tended to deliver the required stability on the blends, in order to avoid sedimentation process. All samples exhibited non-Newtonian flow behavior (shear thinning), increasing PAni content the flow behavior index (n) decreased (0.41 to 0.11) and power law model were used to fitted the experimental curves. The results showed that the addition of PAni-DBSA affects the viscoelastic behavior of the mixtures due to the interactions between the components in the mixture. The best properties were obtained for samples 90/10 wt % dispersed by ultrasonic, indicating the feasibility of the usage as a conducting paint.

Summary
It is well known the insoluble and organic materials which exhibit electrical, magnetic and infusible nature of ICPs has kept them away from the optical properties very similar to metals and semiconductor formation of solutions/melt. The main of this article will compare the rheological behavior of Acrylic Paints/PAni blends and evaluate the influence of sample preparation methodology on the coupling of aniline monomers in the para position and green viscoelastic properties It known the use of PAni, or another form as a protonated emeraldine, which can be dedoped by conducting polymer to improve the corrosion protection, but oxidizing agent to produce the blue, emeraldine base form they’re very little paper showing e rheological behavior after of the semi-conducting polymer[12,13,14]. Useful information for prediction of blends behavior during development of conducting paints, due to it determines the performance of the paint during the whole handling cycle, from storage to application and drying[25,28,29,30]
