The preparation of Nanocomposites is the base of studying the performance of nanocomposites. As nanoparticles surface area and surface tension are great, easily absorbed and reuned, it is very difficult to disperse into nano-particles in its solution. Therefore, the appropriate method, which is able to keep nano-materials in nano-particle size stability, is the most critical problem. Generally, the amount of nano-materials and coatings changes in the relationship similar to the parabola performance curvea, at the beginning, with the addition of nano-materials increased, the performance coatings is significantly improved, to a certain value, an increase of paint will be slow down and finally reach a peak, with the addition of nano-materials further increased, the performance of paint take on a rapidly declining trend, but also increases cost. So, doing a comparison tests, choosing the right amount of nano-materials is very crucial.At First, the interaction between nano-particles is analysed, the results showed that as long as the dispersion of nano-particles larger than in the aggregate of the interaction between the nanoparticles and the interaction force between nanoparticles can be dispersed. To make nanoparticles dispersed homogeneously in the liquid material, the Bubble inflated method is choose to make the nano-anticorrosion conductive paint.Based on the fractal dimension and FBM model the dispersion judgement of nanoparticles is estabilshed,the material is selected. Then the particles adding threshold of identify conductive paint is determinted by the simulation and the threshold is used to decrease the amount of experiment works.According to the simulation results, initially make sure the range of the experimental materials added. Finally, the amount of various materials is confirmed by experiment, at the same time testd the coatings’s corrosion resistance and adhesion capability, prove that the material used in the experiments achieve the standard.
