Example Embodiment
[0019] Example 1:
[0020] First prepare α-zirconium phosphate, then pre-support it with methylamine, and then use cetyltrimethylammonium bromide for further intercalation to obtain organically modified zirconium phosphate; according to the mass ratio of 3 :97 Weigh the organically modified zirconium phosphate and styrene-butadiene-acrylonitrile copolymer, first put the styrene-butadiene-acrylonitrile copolymer in the internal mixer, heat to the molten state and start stirring, then add Organically modified zirconium phosphate, continue to mix and stir for 10 minutes, stop stirring, and take out the composite material formed by the copolymer and the organically modified zirconium phosphate.
[0021] The composite material formed by the copolymer and the organically modified zirconium phosphate is placed in the constant temperature zone of the reaction chamber of the muffle furnace at 360° C., and reacted for 1 hour under the air condition to obtain the product. Figure 1 shows a hi...

[0023] Example 2:
[0024] First prepare α-zirconium phosphate, then pre-support it with ethylamine, and then use octadecyl trimethyl ammonium chloride for further intercalation to obtain organically modified zirconium phosphate; according to the mass ratio of 3 :97 Weigh organically modified zirconium phosphate and butadiene-styrene copolymer; place the butadiene-styrene copolymer in an internal mixer, heat to a molten state and start stirring, then add organically modified zirconium phosphate, continue Mix and stir for 10 minutes, stop stirring, and take out the composite material formed by butadiene-styrene copolymer and organically modified zirconium phosphate.
[0025] The composite material is placed in the constant temperature zone of the reaction chamber of the muffle furnace at 800°C and reacted for 1 hour under air conditions to obtain carbon nanotubes with a length of 200 nm to 6 μm and a diameter of 50 to 200 nm. The carbon nanotube crystals High degree of chemical con...

[0026] Example 3:
[0027] Firstly, α-zirconium phosphate is prepared, and then it is interlayer pre-supported with ethylamine, and then it is further intercalated with tetradecyl dimethyl benzyl ammonium chloride to obtain organically modified zirconium phosphate; Weigh the organically modified zirconium phosphate and butadiene-styrene copolymer at a ratio of 5:95; dissolve the butadiene-styrene copolymer in toluene and place it in a stainless steel reactor lined with polytetrafluoroethylene, and then add it Organically modified zirconium phosphate powder, after stirring evenly, put it in an oven to react at 150°C for 3h; then take out the product and dry it at 80°C for 24h, remove the solvent toluene, and obtain a butadiene-styrene copolymer and organically modified zirconium phosphate. Composite materials.
[0028] The composite material is placed in the constant temperature zone of the reaction chamber of the muffle furnace at 600 DEG C, and reacted under air conditions for 30...
