Embodiment 1

[0056] Plastic substrate PEI 75g, carbon nanotubes 19.5g, silane coupling agent 0.5g, dispersant acrylic acid copolymer 4g, antioxidant tris(2,4-di-tert-butylphenyl ester 1g.

[0057] The above materials are passed through an ordinary twin-screw granulator, and nano-scale carbon tubes / nano-scale carbon black are mixed with plastic substrates and additives to produce ultra-clean anti-static materials. A standard sample was prepared by injection molding using the granular material of Example 1 for performance testing. The transmission electron microscope (TEM) image of the sample of Example 1 shows that carbon nanotubes are uniformly dispersed in the resin material, as shown in FIG. 4 . The scanning electron microscope (SEM) image of the sample of Example 1 shows that carbon nanotubes are uniformly dispersed in the resin material, as shown in FIG. 5 .

Embodiment 2

[0083] The above materials are passed through an ordinary twin-screw granulator, and nano-scale carbon tubes / nano-scale carbon black are mixed with plastic substrates and additives to produce ultra-clean anti-static materials. A standard sample was prepared by injection molding using the granular material of this example for performance testing. The test results are shown in Table 3 and Table 4.

Embodiment 3

[0085] Plastic substrate polypropylene 66.7g, carbon nanofiber 28g, silane coupling agent 0.5g, dispersant LD404 4g, antioxidant tetrakis[methyl-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid] Pentaerythritol ester 0.8g.

[0086] The above materials are passed through an ordinary twin-screw granulator, and nano-scale carbon tubes / nano-scale carbon black are mixed with plastic substrates and additives to produce ultra-clean anti-static materials. A standard sample was prepared by injection molding using the granular material of this example for performance testing. The test results are shown in Table 3 and Table 4

[0087] For the antistatic performance test, the comparison results of the technical indicators of the material in Example 2 and the material in Example 3 are shown in Table 3.
