Performance test
The photonic crystal compositions prepared in examples 1 to 5 were left standing in a natural environment for 6 months to observe whether or not the compositions were delaminated, and the results are shown in table 1.
The photonic crystal compositions prepared in examples 1 to 5 were coated on an optical-grade PET base film, left at an infrared temperature of 45 ℃ for 4min, and passed through an ultraviolet lamp at 200mj/cm2After curing, it was left in air for one year, and the surface hardness, the number of times of abrasion resistance and the surface dyne value were measured and the color was observed, and the results are shown in table 1.
TABLE 1 Performance data for photonic crystal compositions of examples 1-5
| Stability of the System | Hardness of pencil | Number of wear resistance | Surface dyne value | Color(s) | |
| Example 1 | No demixing in 6 months | 2H-750g | ≧ 1000/1000g | 42Dyn/cm | Blue color |
| Example 2 | No demixing in 6 months | 2H-750g | Not less than 1000 times/1000 g | 42Dyn/cm | Red colour |
| Example 3 | No demixing in 6 months | 2H-750g | Not less than 1000 times/1000 g | 42Dyn/cm | Golden color |
| Example 4 | No demixing in 6 months | 2H-850g | ≧ 1200/1000 g | 42Dyn/cm | Golden color |
| Example 5 | No demixing in 6 months | 2H-750g | ≧ 1000 times/1000 g | 42Dyn/cm | Golden color |
By combining examples 1-5 and table 1, it can be seen that the photonic crystal composition prepared by the method has strong system stability, and does not have a delamination phenomenon after being placed for six months, and after a colorful film is prepared by using the photonic crystal composition, a film structure formed by the crystal composition has strong hardness and wear resistance, the surface dyne value is suitable for printing operation, and the color can be adjusted according to the selected additives.
In combination with examples 3 to 5 and Table 1, it can be seen that, when ZIF-8 is added for thermal insulation catalysis before obtaining the photonic crystal composition when preparing the photonic crystal composition, the hardness and wear resistance of the crystal composition after film formation can be improved to a limited extent.
