Problems solved by technology

[0003] However, fullerenes are difficult to dissolve in water, which limits the application of fullerene aqueous solution to prepare negative ion release heads
Fullerenes can only be dissolved in organic solvents, but fullerene dispersions prepared in organic solvents cannot be directly used to prepare negative ion release heads

preparation example Construction

[0053]The method for preparing a fullerene anion releasing head provided by the present invention improves the solubility of fullerene in water through surface modification, significantly shortens the process time for preparing a fullerene anion releasing head by using a fullerene aqueous solution, and improves the anion The production efficiency of the release head reduces the cost. Moreover, dissolving into water, which is finally used to dissolve fullerenes, is a safe, environmentally friendly, and pollutant-free preparation method.

[0054] At the same time, the surface modification has no adverse effect on the performance of the fullerene anion release head, and the prepared fullerene anion release head can still produce ecological grade small particle size negative oxygen with small particle size, high activity, and long migration distance. ions, and the negative ions are of high purity, and there are almost no by-products such as ozone and nitrogen oxides. In addition,...

Description

technical field [0001] The invention relates to anion generating technology, in particular to a fullerene anion releasing head, a preparation method thereof and an anion generating electrode. Background technique [0002] At present, the most advanced negative ion generation technology at home and abroad basically uses a negative high voltage source, and carbon fiber is made into a discharge electrode, that is, the negative ion release head. The anion releasing head is fixed on the metal rod to form the anion generating electrode. When in application, the negative ion generating electrode is connected to a high-voltage power supply, and the negative ion releasing head ejects electrons into the surrounding space at high speed, and the electrons are quickly captured by air ions to form air negative ions. Relatively pure negative ion field. At present, the carbon fiber material used in the more advanced negative ion release heads on the market is mainly fullerene (C60). Full...
