preparation example Construction
[0034] The present invention also provides a preparation method of the antistatic film described in the above technical solution, comprising the following steps:
[0035]The antistatic film is obtained by mixing the electronegative polymer, the triboluminescence material and the solvent, coating on the polyethylene terephthalate plastic (PET) for curing, and then peeling off the film.
[0036] In the present invention, when the electronegative polymer is preferably PVDF, the solvent is preferably a mixture of N,N-dimethylacetamide and acetone, and the N,N-dimethylacetamide The volume ratio of acetone and acetone is preferably 8:12; when the electronegative polymer is preferably polyvinyl chloride, the solvent is preferably tetrahydrofuran.
[0037] In the present invention, the mixing is preferably carried out under the condition of mechanical stirring, the rotational speed of the mechanical stirring is preferably 100-500 r / min, more preferably 200-300 r / min, and the time is p...
Embodiment 1
[0046] Accurately weigh 10 parts of PDMS (Sylgard 184), add 1 part of curing agent Dow Corning 184, add 0 parts, 0.1 parts, 0.3 parts, 0.5 parts of ZnS:Mn 2+ Put the triboluminescent material in a beaker, mechanically stir it at 200r / min for 1 hour to make it evenly mixed, apply it evenly on a PET plastic plate with a scraper, dry it in an oven at 80°C for 2 hours, take it out, and cut it into 4cm×4cm The size of the antistatic film is obtained, the copper electrode is pasted on the back and the wire is drawn out, and the PDMS electrode is obtained. At the same time, mix 2 parts of nylon 11 particles with 9 parts of anhydrous formic acid and 9 parts of dichloromethane and stir for 5 hours to dissolve them, and then spin coat them on copper tape at a speed of 2000 r / min on a spin coater and draw out copper wires. Dry at 60°C for 1 hour to obtain a nylon 11 electrode.
[0047] Add 0 parts of ZnS:Mn to the blank film 2+ Antistatic film obtained by triboluminescent material.

[0050] Accurately weigh 3 parts of PVDF powder, add 8 parts of N,N-dimethylacetamide and 12 parts of acetone, add 0 parts and 0.3 parts of Sr 3 Al 2 o 6 :Eu 3+ , mechanically stirred at a speed of 100r / min for 1 hour to dissolve it, mixed it evenly, evenly scraped it on a PET plastic plate with a scraper, dried it in an oven at 80°C for 2 hours, took it out, and cut it into a size of 4cm×4cm. Obtain an antistatic film, stick a copper electrode on the back and lead out a wire to obtain a PVDF electrode. A nylon 11 electrode was prepared as shown in Example 1.
[0051] The antistatic performance test is carried out by the friction nanogenerator detection method: the PVDF electrode and the nylon 11 electrode are respectively pasted on the inner wall of the motor and the electromagnetic shielding box, and the motor is driven to collect electrical signals. The results show that after adding 0.3 parts of triboluminescent material, the current output 15 times lower and 9 times lo...
