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.

Abstract

This invention relates to a method of using sulfide and perchloro acenaphthylene to prepare organic polymer microsphere. Dissolve sulfide at absolute ethyl alcohol to obtain solution A, dissolve perchloro acenaphthylene at toluene to obtain solution B. By sulfur atom and chlorine atomm, the mol ratio of sulfide and perchloro acenaphthylene is 1: (2 to 3), volume ratio of toluene and absolute ethyl alcohol is 1: (2 to 3). Put solution A and solution B in vessel, then put vessel at reactor to heat to 120 to 180 deg, constant temperature at least 1h, then cooling, gain hybrid; Take underlayer redness deposition of hybrid, respectively use toluene, water and ethanol to rinse at least 1 time, then obtain final product product organic polymer microsphere.

Description

technical field [0001] The invention relates to a polymer microsphere, in particular to a method for synthesizing the polymer microsphere by using sulfide and perchlorinated acenaphthylene through a solvothermal method. Background technique [0002] Polymer microspheres refer to polymer materials or polymer composite materials with diameters ranging from nanometers to micrometers, spherical or other geometric shapes, and their shapes can be varied, including solid, hollow, porous, dumbbell-shaped, Onion type etc. Polymer microspheres also include microcapsules. Microcapsules refer to microspheres with one or more microcavities in the middle of the microspheres, and the microcavities can embed some special substances. Microspheres and microcapsules play special and key roles in many important fields because of their special size and structure. [0003] The application of polymer microsphere materials involves many fields. The earliest synthesized polymer microspheres were ...
