[0014] Example 1
[0015] The method of the invention is adopted to prepare polyethylene rare earth fluorescent fiber.
[0016] Combine 10g polyethylene and 0.1g ternary organic rare earth complex Ln 2 M 1 (M 2 ) R, the particle size is 30nm, put it into the autoclave, add 100ml of solvent 1,2-dichloroethane, stir evenly, heat and pressurize the autoclave, stir for 15min at a temperature of 200℃ and a pressure of 15MPa, make Polyethylene and ternary organic rare earth complex Ln 2 M 1 (M 2 ) R is evenly dispersed in 1,2-dichloroethane. Then the autoclave discharge control valve is opened, the spinning solution is rapidly ejected, the solvent is instantly vaporized and the polyethylene fiber is stretched at a high power, and the three-dimensional network polyethylene rare-earth fluorescent fiber can be obtained on the receiving device.
[0017] Upon inspection, the diameter of the polyethylene rare earth fluorescent fiber prepared in this example is between 500 nm and 5 μm, with an a...

[0018] Example 2
[0019] The polyester rare earth fluorescent fiber is prepared by adopting the method of the invention.
[0020] Combine 8g polyester and 0.05g ternary organic rare earth complex Ln 2 M 1 (M 2 ) R, the particle size is 100nm, put into the autoclave, add 120ml of solvent chloroform, stir evenly and heat and pressurize the autoclave. Stir for 30min at a temperature of 350℃ and a pressure of 20MPa to make the polyester and the ternary organic rare earth complex Ln 2 M 1 (M 2 )R is evenly dispersed in chloroform, and then the autoclave discharge control valve is opened, so that the spinning solution is sprayed out quickly, the solvent is instantly vaporized and the polyester fiber is stretched at a high power, and the three-dimensional network polyester can be obtained on the receiving device Fluorescent fiber.
[0021] Upon inspection, the diameter of the polyester fluorescent fiber prepared in this example is between 200 nm and 5 μm, with an average value of 1.5 μm. ...

[0022] Example 3
[0023] The method of the invention is adopted to prepare polyvinylidene fluoride rare earth fluorescent fiber.
[0024] Combine 12g polyvinylidene fluoride and 0.2g ternary organic rare earth complex Ln 2 M 1 (M 2 ) R, the particle size is 50nm, put into the autoclave, add 150ml of solvent cyclohexane, stir evenly and heat and pressurize the autoclave. At a temperature of 220℃ and a pressure of 20MPa, stir for 30 minutes to make the polyvinylidene fluoride and the ternary organic rare earth complex Ln 2 M 1 (M 2 ) R is evenly dispersed in cyclohexane, and then the autoclave discharge control valve is opened, the spinning solution is sprayed out quickly, the solvent is vaporized instantaneously, and the polyvinylidene fluoride fiber is conventionally high-stretched, and it can be obtained on the receiving device Three-dimensional reticulated polyvinylidene fluoride fluorescent fiber.
[0025] Upon inspection, the diameter of the polyvinylidene fluoride fluorescent ...
