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 an aqueous solution of ferric nitrate with a mass concentration of 0.1%, and stir them evenly. Subsequently, 0.5 mL of sodium hydroxide aqueous solution with a concentration of 2.96 wt% was added and stirred uniformly. The resulting mixture was filtered and dried for 20 hours at a temperature of 110°C; the dried sample was roasted at 450°C for 4.5 hours. Put the treated natural mordenite into a chemical vapor deposition furnace, purge the furnace tube with inert gas for 20 minutes, and then pass hydrogen into the furnace tube. The hydrogen flow rate is 25mL / min. The temperature is raised from room temperature to 500°C at a rate of 7.5 ℃ / min; At this time, a mixture of ethylene and hydrogen gas with a volume ratio of 1:1 is introduced, the reaction temperature is increased to 750℃, the heating rate is 1℃ / min, and the temperature is kept at 750℃ for 2h to obtain carbon nanotubes-natural mercerizing Zeolite hybrid material A.

Embodiment 2

[0029] In Example 1, the concentration of the sodium hydroxide aqueous solution was reduced to 0.74 wt%, and the other operation methods and material composition were unchanged, and the carbon nanotube-natural mordenite hybrid material B was obtained.

Embodiment 3

[0031] In Example 1, the concentration of the sodium hydroxide aqueous solution was increased to 14.8% by weight, and the other operation methods and material composition were unchanged, and the carbon nanotube-natural mordenite hybrid material C was obtained.

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 natural inorganic layered silicate materials. Background technique [0002] Organic-inorganic hybrid materials are one of the excellent materials for modified polyester elastomers. Natural inorganic layered silicate materials have excellent heat resistance and dimensional stability, and are increasingly used in the modification of polyester elastomers. Carbon nanotubes are also functionalized and reinforced materials for polyester elastomers, which can significantly improve the strength and toughness of polyester elastomers. However, currently prepared natural inorganic layered silicate materials and carbon nanotube-reinforced materials are mostly directly blended and reinforced, or the two types of materials are modified and then blended ...
