Examples
Embodiment 1
[0017] Dissolve 78mg of sodium sulfide nonahydrate in 5ml of absolute ethanol, dissolve 21mg of perchlorinated acenaphthylene in 10ml of toluene, mix the above-mentioned two solutions into a polytetrafluoroethylene liner with a volume of 18ml, and dissolve the polytetrafluoroethylene The lining is placed in a reaction kettle, kept at 180°C for 72 hours, and then cooled to room temperature, then the polytetrafluoroethylene lining is taken out and the solution is poured out, centrifuged with a 5ml centrifuge tube, and the solid product obtained is washed with toluene, ethanol and water successively. After washing 5 times, the target product was obtained.
[0018] Depend on figure 1 It can be seen that the obtained polymer microspheres have good dispersibility, and the particle size is about 1 μm.
Embodiment 2
[0020] Dissolve 36mg of potassium sulfide in 5ml of absolute ethanol, dissolve 21mg of perchlorinated acenaphthylene in 10ml of toluene, mix the above-mentioned two solutions into a polytetrafluoroethylene lining with a volume of 18ml, and put the polytetrafluoroethylene lining Place in a reaction kettle, keep the temperature at 180°C for 72 hours, then cool to room temperature, take out the polytetrafluoroethylene liner and pour out the solution, centrifuge with a 5ml centrifuge tube, and wash the solid product successively with toluene, ethanol, and water for 5 Repeatedly, the target product can be obtained.
[0021] Depend on figure 2 It can be seen that the dispersibility of the microspheres prepared with potassium sulfide as raw material is not as good as that of the polymer microspheres prepared with potassium sulfide as raw material, and the obtained microspheres are about 0.5-1 μm, and a small part of the microspheres are about several μm.
Embodiment 3
[0023] Dissolve 78mg of sodium sulfide nonahydrate in 5ml of absolute ethanol, dissolve 21mg of perchlorinated acenaphthylene in 10ml of toluene, mix the above two solutions in a polytetrafluoroethylene liner with a volume of 18ml, and put the polytetrafluoroethylene Place the ethylene lining in the reaction kettle, keep the temperature at 180°C for 1 hour, then cool to room temperature, take out the polytetrafluoroethylene lining and pour out the solution, centrifuge with a 5ml centrifuge tube, and the solid product obtained is washed with toluene, ethanol, water Each was washed 5 times to obtain the target product.
