FIG 6.3 TEM particle size distribution and FIGS MnO2 / PPy composite fine emulsion prepared for different synthetic emulsifying device. As can be seen from the figure, the composite materials are prepared three nanoflowers emulsifying device structure, and more uniform particle size, a significant improvement in the degree of agglomeration. Petaloid porous composite structure described, considerably increases the specific surface area, which provides a diffusion path for ions in the electrolyte, to improve the utilization of the active material. FIG. 6.3 (d) of the particle size distribution can be seen that the distribution curve of normal distribution, a particle size range of 90-300 nm, an average particle diameter of 150 nm, than TEM measured particle size slightly, because the measurement is during a certain amount of surface adsorbed solvent molecules caused. Diameter of the composite material prepared in a high speed disperser slightly wider profile than the other two, which is depending on the size and the size of the composite particle miniemulsion droplets relevant, it can be seen from FIGS. 6.1 and 6.1, compared to other terasodium means miniemulsion droplets produced high speed disperser larger droplet size and wide distribution, so the use of the composite prepared miniemulsion particle size also larger.

Figure 6.3 Tem and particle size maps of MnO2/PPy composites made of fine emulsion synthesis from different emulsified devices. It can be seen from the figure that the composite materials prepared by the three emulsified devices are all nanoflower-like structures, and the particle size is more homogenous, and the degree of reunion has improved significantly. Petal-shaped structure shows that the composite material is porous, which is greatly increased than the surface area, which provides a channel for the diffusion of electrolyte ions and improves the utilization rate of the active substance. Figure 6.3(d) particle size distribution map can be seen that the distribution curve is a normal distribution, particle size range of 90-300 nm, the average particle size of 150 nm, slightly higher than TEM measured, because of the measurement process of surface adsorption of a certain amount of solvent molecules. The particle size distribution of the composite material prepared by the high-speed disperser is slightly wider than the other two, which is due to the size of the particle size of the composite material and the size of the fine emulsion droplet, from Figure 6.1 and Table 6.1 can be seen, compared with the other two emulsified devices, the high-speed disperser prepared the fine emulsion droplet is larger, and the droplet size distribution is wider, so the particle size of the composite material prepared by using the fine emulsion is also larger.

Fig. 6.3 TEM diagram and particle size distribution of MnO2/PPy composites prepared by miniemulsion polymerization with different emulsification devices. It can be seen from the figure that the composite materials prepared by the three emulsification devices are of nano flower structure, and the particle size is relatively uniform, and the degree of agglomeration is significantly improved. Petal like structure shows that the composite is porous and the specific surface area is greatly increased, which provides a channel for the diffusion of electrolyte ions and improves the utilization rate of active substances. It can be seen from the particle size distribution diagram in Fig. 6.3 (d) that the distribution curve is normal, the particle size range is 90-300 nm, and the average particle size is 150 nm, which is slightly higher than the particle size measured by TEM, because of a certain amount of solvent molecules adsorbed on the surface during the measurement. The particle size distribution of composite materials prepared by high-speed dispersions is slightly wider than that of the other two. This is due to the size of the composite particles and the size of the droplets. It can be seen from Figure 6.1 and Table 6.1 that compared with the other two emulsifying devices, the droplet size of the miniemulsion produced by the high-speed disperser is larger and the droplet size distribution is wider, so the particle size of the composite material prepared by using the miniemulsion is larger. It's bigger.
