Negative ion generation
As a piezoelectric material, graphene is capable of relαeasing 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, regula±te nerve function, eliminate fatigue, slow heart rate, reducing blood pressure of hypertensi∞ve patients tends to normal level, and can also strengthen t♣he ciliary movement of the respiratory surface.
