| titleOfInvention | A high-efficiency purification method of water-dispersible carbon nanomaterials |
| abstract | The invention provides a high-efficiency purification method for water-dispersible carbon nanomaterials. Dissolve the ball-milled mixture of carbon nanomaterials, water-soluble azo dye molecules and derivatized modified molecules with water, then mix it with the inorganic salt/alkali aqueous solution, and centrifuge at a centrifugal speed of 3,000-10,000 rpm for 1-30 minutes , suck out the upper dye aqueous solution, then add water to ultrasonically dissolve the bottom precipitate; repeat the above-mentioned salting-out-assisted centrifugation purification process until washing to obtain carbon nanomaterials dispersed in water. The outstanding feature of the present invention is: using common alkalis and salts as auxiliary sedimentation agents, the efficient separation of free dye molecules and water-dispersible carbon nanomaterials can be achieved in a short time and at a low centrifugal speed. The loss of nanomaterials is small, the purification reagent is environmentally friendly, and the cost is low, and the purification process has no effect on the physical and chemical properties of the carbon nanomaterials in terms of water dispersibility and optoelectronic properties. |
