Example Embodiment

[0021] Example 1

[0022] 78mg of sodium sulfide nonahydrate was dissolved in 16ml of absolute ethanol to obtain solution A. 20mg of perchlorobenzoacenaphthylene was added to 0.5ml of toluene to obtain mixture B. Ultrasound for 30s. Add the above-obtained solution A and mixture B to a volume of 18ml In the PTFE lining, ultrasonic for 30s, place the PTFE lining in the reactor and heat it to 180°C for 72h, then cool to room temperature, take out the PTFE lining, and remove the PTFE lining in the lining. The mixture was poured out, centrifuged with a 5ml centrifuge tube, and the obtained solid product was washed 5 times with toluene, ethanol and water in turn to obtain the target product.

[0023] From the SEM image (see Figure 1), it can be seen that the length of the obtained organic polymer nanotubes is mostly a few micrometers to more than ten micrometers. It can be seen from the TEM image (see the enlarged image on the upper right of FIG. 1) that the tube diameter of the obtaine...

[0024] Example 2

[0025] 78mg of sodium sulfide nonahydrate was dissolved in 16ml of absolute ethanol to obtain solution A. 20mg of perchlorobenzoacenaphthylene was added to 1ml of cyclohexane to obtain mixture B. Ultrasound for 30s. Add the above obtained solution A and mixture B to a volume of 18ml In the PTFE lining, ultrasonic for 30s, place the PTFE lining in the reaction kettle and heat it to 180°C for 72h, and then take out the PTFE lining after cooling to room temperature. The mixture was poured out, centrifuged with a 5ml centrifuge tube, and the obtained solid product was washed 5 times with toluene, ethanol and water in turn to obtain the target product.

[0026] From the SEM image (see Figure 2), it can be seen that the morphology of the organic polymer prepared with cyclohexane and ethanol as solvents is similar to the morphology of polymer nanotubes prepared with toluene and ethanol as solvents.

Abstract

A method for producing organic macromolecule nano tube by sodium sulfide and perchlorobenzoacenaphthylene relates to a organic macromolecule nano tube. The method comprising: dissolving the sldium monosulfide in the absolute ethyl alcohol to get solution A, adding the perchlorobenzoacenaphthylene into the solvent to get mixture B, ultrasonic treatment to the mixture B; feeding solution A and B in a container for ultrasonic treatment, heating the container in the reaction vessel at least 1 hour at constant temperature, cooling, getting mixture C; taking the underlayer red deposit of the mixture C, washing at least a time with toluene, water and ethanol. Wherein, sldium monosulfide sulfur atoms: perchlorobenzoacenaphthylene chlorin atoms=1:2-3 according to the molar ratio, and solvnt:absolute ethyl alcohol=1:16-32, the solvent is chosen from one of toluene, cyclohexane or tetrahydrofuran.

Description

technical field [0001] The invention relates to an organic polymer nanotube, in particular to a method for preparing an organic polymer nanotube by utilizing sodium sulfide and perchlorinated benzoacenaphthylenene through a solvothermal method. Background technique [0002] Starting with the discovery of carbon nanotubes (CNTs) by Japanese scientist Iijima in the early 1990s, nanoscience and technology has rapidly developed into a new branch of discipline. With the vigorous development in nano science and technology, nano science and technology has become a research hotspot today. Nanomaterials have become one of the three hotspots in science and technology that people pay attention to in the new century. Nanomaterial systems have broad application prospects due to their many unusual physical and chemical properties, and involve many disciplines such as atomic physics, condensed matter physics, colloid chemistry, coordination chemistry, chemical reaction kinetics, and surfa...
