Negative ion generation
As a piezoelectric material, graphene is capable of releasing abundant negative ions. And graphene functional fiber is safe and environmentally friendly.
Negative ions are called "vitamins of the air" and have two major functions:
1. Air purification: remove dust and decompose harmful gases.
2.Health care: improve brain function, increase body immunity, promote metabolism, regulate nerve function, eliminate fatigue, slow heart rate, reducing blood pressure of hypertensive patients tends to normal level, and can also strengthen the ciliary movement of the respiratory surface.
