Comparative example 1: on the basis of example 6, no antibacterial agent was added, and the remaining steps and parameters were kept unchanged, to prepare a pickles racket.
Comparative example 2: on the basis of example 6, no cyclodextrin was added, and the remaining steps and parameters were kept unchanged, to prepare a pickles racket.
Comparative example 3: on the basis of example 6, the Pickering racket is prepared without adding cyclodextrin and antibacterial agent, and the rest steps and parameters are kept unchanged.
The examples 4-6 and comparative examples 1-3 were tested for compressive strength according to GB/T8813-2008 test, and the results are shown in Table 1:
TABLE 1
| Item | Example 4 | Example 5 | Example 6 | Comparative example 1 | Comparative example 2 | Comparative example 3 |
| Compressive strength/MPa | 0.389 | 0.390 | 0.391 | 0.389 | 0.273 | 0.273 |
As can be seen from Table 1, the anti-slip layer added with cyclodextrin has better compressive strength.
The antibacterial performance of the picket rackets in examples 4 to 6 and comparative examples 1 to 3 was evaluated according to the agar plate diffusion method, specifically: culturing activated Escherichia coli in nutrient broth for 24h, and diluting with distilled water to 20 times of original volume; preparing 6 clean culture dishes, adding agar culture media with one third volume into the culture dishes, adding 100 mu L of diluted bacterial liquid into each culture medium, and uniformly smearing the diluted bacterial liquid by using a sterile ring;
the anti-slip layer of each of the Pickering racket of examples 4 to 6 and comparative examples 1 to 3 was cut into disks each having a thickness of 5mm and a diameter of 10mm, washed with distilled water for 30 seconds, placed at the center of each dish with a sterile forceps, incubated at 37 ℃ for 24 hours in an incubator, and the diameters of the respective zones (including the diameter of the disk) were measured after the incubation. The results are shown in table 2:
TABLE 2
| Item | Example 4 | Example 5 | Example 6 | Comparative example 1 | Comparative example 2 | Comparative example 3 |
| Diameter/mm of zone of inhibition | 13.6 | 13.6 | 13.7 | 10.9 | 13.6 | 10.9 |
As can be seen from Table 2, the anti-slip layer of the Picker racket prepared in examples 4-6 has a better bacteriostatic effect.
