[0071] Results Analysis

[0072] The following combines the experimental data provided in Table 1-2 and Figure 1-2 This application will be described in detail.

[0073] In Examples 1-7 of this application, the molybdenum disulfide nanotube-carbon nanotube hybrid materials all feature multi-walled carbon nanotubes tightly wrapped around a molybdenum disulfide nanotube structure, successfully forming a molybdenum disulfide nanotube-carbon nanotube hybrid structure. In Example 5, the molybdenum disulfide nanotube-carbon nanotube hybrid material is as follows: Figure 1 As shown, Figure 1 As can be seen in (a), in the molybdenum disulfide nanotube-carbon nanotube hybrid material, multi-walled carbon nanotubes and molybdenum disulfide nanotubes form a tight three-dimensional network structure as a whole. Figure 1 As can be seen in (b), multi-walled carbon nanotubes are interwoven and wrapped around molybdenum disulfide nanotubes, and are densely distributed.

[0074] Referring to Table 1, the molybdenum disulfide nanotube-carbon nanotube-polyetheretherketone (PEEK) composites of Examples 1-7 showed significant improvements in compressive strength and surface hardness compared to the PEEK composites of Comparative Example 1 and Comparative Example 2 (carbon nanotube-PEEK). This indicates that the addition of molybdenum disulfide nanotube-carbon nanotube hybrid materials is beneficial to improving the mechanical properties of PEEK and its composites. In particular, when the weight ratio of sodium molybdate dihydrate to multi-walled carbon nanotubes was 1.18:1, the compressive strength of the molybdenum disulfide nanotube-carbon nanotube-PEEK composite of Example 1 increased by approximately 23.77% (from 149.3 MPa to 184.79 MPa) and the surface hardness also increased by 5.36% (from 85.5 HD to 90.08 HD) compared to the PEEK composite of Comparative Example 1, and the compressive strength and surface hardness were also significantly improved compared to the carbon nanotube-PEEK composite of Comparative Example 2. This indicates that the molybdenum disulfide nanotube structure and the carbon nanotube structure have a synergistic effect in improving the mechanical properties of polyetheretherketone (PEEK) composite materials prepared by adjusting the ratio of molybdenum precursor to carbon nanotubes in the range of 0.5-10:1.

[0075] Referring to Table 2, the molybdenum disulfide nanotube-carbon nanotube-polyetheretherketone (PEEK) composites of Examples 1-7 exhibited lower coefficients of friction and superior wear resistance compared to the PEEK composites of Comparative Example 1 and the carbon nanotube-PEEK composites of Comparative Example 2 in the tribological tests. In particular, when the weight ratio of sodium molybdate dihydrate to multi-walled carbon nanotubes was 1.18:1, the coefficient of friction of the molybdenum disulfide nanotube-carbon nanotube-PEEK composite of Example 1 decreased by approximately 23.73% (from 0.295 to 0.225) compared to the PEEK composite of Comparative Example 1, and the wear resistance increased by 88.95% (from 54.83 × 10⁻⁶ mm). 3 / N·m decreased to 6.06×10⁻⁶ mm 3 The friction reduction and wear resistance of the carbon nanotube-polyetheretherketone composite materials in Examples 1-7 were significantly improved compared to Comparative Example 2. This indicates that the molybdenum disulfide nanotube structure and the carbon nanotube structure in the molybdenum disulfide nanotube-carbon nanotube hybrid materials prepared by controlling the ratio of molybdenum precursor to carbon nanotubes at 0.5-10:1 have a synergistic effect in improving the tribological properties of polyetheretherketone-based composite materials.

[0076] In summary, the molybdenum disulfide nanotube-carbon nanotube-polyetheretherketone (PEEK) composites of Examples 1-7 exhibit significant advantages in both mechanical and tribological properties compared to the PEEK composites of Comparative Example 1 and Comparative Example 2 (carbon nanotube-PEEK). This is attributed to the fact that the molybdenum disulfide nanotube-carbon nanotube hybrid material, formed by the molybdenum disulfide nanotubes and multi-walled carbon nanotubes, provides an effective stress transfer network for the PEEK matrix. Furthermore, the hollow tubular structure of both the molybdenum disulfide nanotubes and multi-walled carbon nanotubes in the molybdenum disulfide nanotube-carbon nanotube-PEEK composite material further enhances its lubrication performance. The synergistic effect of the molybdenum disulfide nanotube structure and the multi-walled carbon nanotube structure in the molybdenum disulfide nanotube-carbon nanotube-PEEK composite material simultaneously improves both its mechanical and tribological properties.

[0077] Furthermore, refer to Figure 2 In Comparative Example 3, the molybdenum disulfide nanoflower-carbon nanotube-polyetheretherketone composite material is connected by multi-walled carbon nanotubes to form a molybdenum disulfide nanoflower-carbon nanotube hybrid material. Comparative Example 3 serves as a control. Figure 1 In Example 5, the ratio of molybdenum disulfide nanotubes to carbon nanotubes in the molybdenum disulfide nanotube-carbon nanotube-polyetheretherketone composite material was comparable to that in Comparative Example 3, but the molybdenum disulfide nanoflower-carbon nanotube-polyetheretherketone composite material in Example 5 exhibited superior mechanical properties (compression performance and surface hardness) and tribological properties (wear resistance) compared to Comparative Example 3. Furthermore, the compression performance, surface hardness, and wear resistance of the molybdenum disulfide nanoflower-carbon nanotube-polyetheretherketone composite materials in Examples 3-5 were all superior to those in Comparative Example 3, indicating that a weight ratio of sodium molybdate dihydrate to multi-walled carbon nanotubes of 1-5:1 is beneficial for further improving the mechanical properties and wear resistance of the molybdenum disulfide nanoflower-carbon nanotube-polyetheretherketone composite material.
