Problems solved by technology

However, the catalytic effect of the supported metal catalyst is not high, that is, the carbon nanotubes grown between the montmorillonite are easy to fall off, and do not really grow in the pores of the inorganic layered silicate material.
In addition, adopting the above-mentioned preparation method, including the technical route of flame heating and combustion, the energy consumption is relatively high

Embodiment 1

[0027] Weigh 1 mL of natural mordenite and 5 mL of ferric nitrate aqueous solution with a mass concentration of 0.1%, and stir evenly. Then add 0.5 mL of aqueous sodium hydroxide solution with a concentration of 2.96 wt%, and stir evenly. The resulting mixture is filtered and dried for 20 hours at 110°C; the dried sample is roasted at 450°C for 4.5 hours. Put the treated natural mordenite into a chemical vapor deposition furnace, purge the furnace tube with an inert gas for 20 minutes, then pass hydrogen into the furnace tube, the hydrogen flow rate is 25 mL / min, and the temperature is raised from room temperature to 500 ° C, and the heating rate is 7.5 ℃ / min; At this time, a mixed gas of ethylene and hydrogen with a volume ratio of 1:1 is introduced, and the reaction temperature is raised to 750°C at a heating rate of 1°C / min. After reaching 750°C, the temperature is kept constant for 2 hours to obtain carbon nanotubes-natural silk Zeolite Hybrid Material A.

Description

technical field [0001] The invention relates to an organic-inorganic hybrid material and a preparation method thereof, in particular to a preparation method for synthesizing a carbon nanotube-inorganic layered silicate hybrid material by using a natural inorganic layered silicate material. Background technique [0002] Organic-inorganic hybrid materials are one of the excellent materials for modifying polyester elastomers. Natural inorganic layered silicate materials have excellent heat resistance and dimensional stability, and are increasingly used in the modification research of polyester elastomers. Carbon nanotubes are also functionalized and reinforcing materials for polyester elastomers, which can significantly improve the strength and toughness of polyester elastomers. However, most of the currently prepared natural inorganic layered silicate materials and carbon nanotube-reinforced materials are enhanced by direct blending, or the two types of materials are modified...
