Figure 6.4 is a different emulsification device MnO2 / PPy specific surface area of ​​the composite compare FIG. It is seen from FIG, MnO2 / PPy Composite adsorption - desorption isotherms belong IUPAC curve classification category Ⅳ adsorption isotherm, specific surface area of ​​the size of the composite material prepared as follows: an ultrasonic cell crusher> IS-RPB> high speed disperser. Over the entire pressure range, the concave isotherm, capillary agglomeration occurred in the latter half, the adsorption amount increases sharply. Can be intuitively seen from Table 6.4, calculated by BET, specific surface area of ​​the composite material prepared ultrasonic cell crusher, IS-RPB and high-speed disperser followed by 231.3 m2 g-1,177.1 m2 g-1,145.0 m2 g- 1, and adsorption - desorption isotherms consistent results. Composites with increasing average pore diameter, pore volume of the composite material prepared ultrasonic cell crusher, IS-RPB gradually decreases and high-speed disperser. The average pore diameter of MnO2 / PPy composite were between 3-4 nm, said composite material is prepared by emulsion method details mesoporous materials.

Figure 6.4 is a comparison of the surface area of MnO2/PPy composite synths under different emulsified devices. As can be seen from the figure, the adsorption-deattached isometric line of MnO2/PPy composite material belongs to the IV class adsorption isometric temperature line in the IUPAC curve classification, and the ratio area of the prepared composite material is: ultrasonic cell crusher and IS-RPB and high-speed disperser. In the whole pressure range, the sociable line is concave downwards, and the condensation of capillary tubes occurs in the second half of the period, and the adsorption increases sharply. Table 6.4 can be intuitively seen, calculated by BET, ultrasonic cell crusher, IS-RPB and high-speed disperser prepared composite materials, the surface area of 231.3 m2 g-1, 177.1 m2 g-1, 145.0 m2 g-1, and adsorption-deattached isometric line results. With the increase of the average aperture of composite materials, the hole capacity of the composite materials prepared by ultrasonic cell crushers, IS-RPBs and high-speed dispersers is gradually reduced. The average aperture of MnO2/PPy composite synths is between 3-4 nm, and the composite material prepared by the detailed emulsion method is a mesoporous material.

Figure 6.4 shows the comparison of specific surface area of MnO2 / PPy composite under different emulsification devices. It can be seen from the figure that the adsorption desorption isotherms of MnO2 / PPy composite belong to the IV adsorption isotherms in IUPAC curve classification, and the specific surface area of the composite prepared is in order: Ultrasonic Cell Crusher > IS-RPB > high-speed disperser. In the whole pressure range, the isotherm is concave downward, and the capillary condensation occurs in the second half, and the adsorption capacity increases sharply. It can be seen directly from table 6.4 that the specific surface area of the composite prepared by ultrasonic cell breaker, IS-RPB and high-speed disperser is 231.3m2 g-1, 177.1m2g-1 and 145.0m2g-1, which is consistent with the results of adsorption desorption isotherm. With the increase of the average pore size of the composite, the pore volume of the composite prepared by ultrasonic cell breaker, IS-RPB and high-speed disperser decreased gradually. The average pore size of MnO2/PPy composites is 3-4 nm, indicating that the composites prepared by miniemulsion method are mesoporous materials.
