Figure 5.7 shows the effect of different overweight factor beta on the ratio capacity of MnO2/PPy composite electrode materials. The reaction conditions are: p-TSA concentration of 0.84 mol L-1, impact speed u is 9.43 m?s-1, KMnO4 concentration is 0.094 mol L-1, reaction time is 3.5 h. As can be seen from the figure, the MnO2/PPy ratio capacity increases with the increase of beta at different current densities, and when it increases to a certain extent, the ratio decreases. This can be explained from the stabilization mechanism of monomer droplets, oil, water two-phase emulsification requires a certain amount of energy input, beta increase makes the filler line speed increase, the shearing force of the emulsion significantly enhanced, thus forming a nano-scale fine droplets, fine emulsion system emulsifier can be fully adsorbed on the surface of small droplets, to prevent the occurrence of ostwald maturation between droplets And, when beta exceeds 65.32, the continued increase in speed will cause the droplet size to further decrease, the increase of droplet ratio surface area makes the surface tension increase, the emulsifier on the surface of the single droplet is not enough to maintain the stability of the droplet, the small droplet to the large droplet migration rate is accelerated, coupled with the high degree of mixing collision, resulting in the stability of the fine emulsion, the impact on the structure of MnO2/PyP composite material, the impact on the ratio is also reduced.
