[0002] With the development of industrialization and electronic technology, static electricity problems are becoming increasingly serious in fields such as electronic equipment, textiles, and medical devices. Most existing antistatic agents rely on conductive polymers or inorganic fillers, but the antistatic effects of these traditional materials are often not durable, and their electrostatic protection performance significantly decreases after long-term use or surface damage. Especially in high-end electronic products and precision instruments, static electricity accumulation can lead to equipment malfunctions or material damage; therefore, there is a need to develop a highly efficient and durable antistatic agent.

[0003] In recent years, research on the application of quantum materials and self-healing materials has made some progress. Quantum materials can regulate charge transfer paths, while self-healing materials improve the long-term stability of materials through their repair functions. However, the combination of quantum materials and self-healing materials in antistatic agents has not been widely studied. Currently, no antistatic agent possesses both quantum effect regulation and self-healing capabilities to address the stability and durability issues of traditional antistatic materials.

[0004] Therefore, this invention proposes a novel antistatic agent that utilizes quantum materials to regulate charge release pathways and combines the repair function of self-healing materials to provide long-lasting and efficient static electricity management. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a highly effective and durable antistatic agent that combines quantum control and self-healing functions, along with its preparation method. This antistatic agent integrates the charge migration path regulation of quantum materials with the automatic repair function of self-healing materials, improving static discharge efficiency and ensuring stability during long-term use, thus meeting the electrostatic protection requirements in various complex environments.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A highly effective and long-lasting antistatic agent, said antistatic agent being prepared from the following raw materials in parts by weight: Quantum materials 0.1–30 parts, self-healing polymer 30–60 parts, conductive polymer 10–50 parts, surfactant 0.1–10 parts, dispersion medium 100–250 parts; The quantum material regulates charge migration paths through quantum effects, the self-healing nanomaterial restores its antistatic properties through automatic repair, the conductive polymer enhances the conductivity of the antistatic agent, and the surfactant optimizes its dispersibility and stability.

[0022] Performance testing 1. Electrostatic discharge performance test Electrostatic discharge performance testing is used to verify the release efficiency of antistatic agents after static electricity accumulation, to evaluate their electrostatic management capabilities in practical applications, and to demonstrate the innovative aspects of quantum materials in regulating charge migration paths. At the start of the test, a sample coated with the antistatic agent is taken, ensuring a uniform coating and a surface size of 5 cm × 5 cm. The sample is then placed in an electrostatic field, and an electrostatic generator (5000V) is used to accumulate static electricity on the sample surface for 10 minutes. After accumulation, the sample is moved to the Faraday Cup electrostatic discharge testing apparatus, and the amount of charge released is measured at 1 second, 5 seconds, 10 seconds, 30 seconds, 1 minute, and 5 minutes, recording the amount of charge released during the electrostatic discharge process. By measuring the rate and efficiency of electrostatic discharge, an electrostatic discharge curve is plotted, and the electrostatic discharge efficiency is calculated to verify the contribution of quantum materials in improving electrostatic discharge efficiency. To ensure the stability of the results, the test must be repeated at least three times, and the average value is taken as the final result.

[0023] Table 1. Electrostatic discharge performance test data of different samples (unit: mC)

[0024] The antistatic agent in Example 1 achieved an electrostatic release efficiency of 95%, which was significantly better than that in Comparative Example 1 and Comparative Example 2, verifying the significant improvement of electrostatic release performance by quantum materials.

[0025] 2. Self-healing performance test The self-healing performance test is used to evaluate the self-healing ability of antistatic agents to verify the repair effect and long-term stability of self-healing nanomaterials. First, a sample coated with antistatic agent is taken, ensuring a uniform coating on the sample surface, with a size of 5 cm × 5 cm. Artificial damage is then applied to the surface using a scraper or needle tool to scratch or puncture the sample surface, with a damage area of ​​1 cm² and a depth of 0.1 mm. The damaged sample is then placed at room temperature or heated to 50°C for 24 hours to promote self-healing. After self-healing, the surface hardness, gloss, and post-repair antistatic properties of the sample are measured using a hardness tester and a tensile testing machine, and the self-healing rate is calculated.

[0026] Table 2. Test data on the self-healing performance of different samples

[0027] The electrostatic release efficiency of the examples is higher than 90%. The electrostatic release efficiency of Comparative Example 1 is 60% when quantum materials are lacking, and the electrostatic release efficiency of Comparative Example 2 is 65% when self-healing polymer is lacking. This shows that the synergistic effect of self-healing polymer and quantum materials can simultaneously improve the electrostatic release efficiency and self-healing rate of antistatic agent.

[0028] 3. Coating adhesion test Take a sample coated with an antistatic agent, ensuring a uniform surface coating, measuring 5 cm × 5 cm, and select a suitable substrate. Then, use a pull-out tester (pull-out speed 1 mm / min) or a shear tester (shear speed 5 mm / min) to measure the adhesion between the coating and the substrate. Next, conduct friction or impact tests to simulate the coating's durability in practical applications, with 1000 friction cycles and 1 J of impact energy. After the tests, measure the adhesion again and calculate the adhesion retention rate to evaluate the coating's long-term stability. This test ensures that the coating maintains a stable electrostatic discharge effect under harsh environments and guarantees its long-term effectiveness.

[0029] Table 3. Coating adhesion test data for different samples

[0030] The coating adhesion tests of Examples 1-3 showed high adhesion retention rates and good wear resistance and impact resistance. The adhesion of Comparative Examples 1 and 2 was low, indicating that the physical stability and durability of the coating decreased significantly in the absence of quantum materials or self-healing materials.

[0031] 4. Corrosion resistance test Take a sample coated with an antistatic agent, ensuring a uniform surface coating, and measure 5 cm × 5 cm. Expose the sample to salt spray conditions using a 5% NaCl solution for 1000 h at a temperature of 35°C. Alternatively, expose the sample to acid or alkaline solutions, such as hydrochloric acid solution at pH 3 or sodium hydroxide solution at pH 12, for 24 h. Regularly check the appearance, corrosion level, and antistatic properties of the sample, and record changes in electrostatic discharge efficiency and self-healing rate. These tests evaluate the corrosion resistance and long-term stability of the antistatic agent coating.

[0032] Table 4 Corrosion resistance test data for different samples

[0033] According to the data in the table, Examples 1-3 maintained high antistatic efficiency in salt spray and acid / alkali environments, with self-healing rates all exceeding 97%, and the coatings showed minimal changes in physical properties, exhibiting excellent corrosion resistance. In contrast, Comparative Examples 1 and 2 showed significantly reduced antistatic efficiency and self-healing rates in salt spray and acid / alkali environments, indicating that the lack of quantum materials or self-healing materials significantly affects the long-term stability and corrosion resistance of the coatings.
