Description

Technical Field

[0001] The invention relates to the technical field of negative oxygen ion materials, in particular to a nano composite material capable of releasing negative oxygen ions. Background Art

[0002] Negative oxygen ions can promote the synthesis and storage of vitamins in the human body, strengthen and activate the physiological activities of the human body, so it is called "air vitamins". It is believed that it has a very important impact on the life activities of the human body and other organisms, just like vitamins in food. For example, after a thunderstorm, the negative oxygen ions in the air increase, and people feel happy. In the medical field, negative oxygen ions are confirmed to be an effective means of killing germs and purifying the air. Its mechanism is mainly that after the negative oxygen ions combine with bacteria, the bacteria will undergo structural changes or energy transfer, leading to the death of the bacteria and eventually sinking to the ground.

[0003] The functionality of negative oxygen ions improves our health. However, many existing materials have limited negative oxygen ion release, which is difficult to meet actual needs, especially in severely polluted environments.
