Efficient protecting mask taking triboelectric nano power generator as filtering layer

Abstract

The invention discloses an efficient protecting mask taking a triboelectric nano power generator as a filtering layer. The efficient protecting mask is formed by arranging the triboelectric nano power generator in a ventilation cover of the protecting mask, the triboelectric nano power generator is composed of an upper friction pole plate and a lower friction pole plate, the upper friction pole plate is formed by growing a ZnO nano array on one side of nonwoven cloth and serves as a friction layer obtaining electrons, nano Ag conductive ink coats the other side of the nonwoven cloth to serve as an output electrode, the lower friction pole plate is formed by magnetron sputtering of metal Al on one side of a copper net with 200 meshes and serves as a friction layer losing electrons, the other side of the copper net serves as an output electrode, and the lower friction pole plate of the triboelectric nano power generator is fixed to a bottom ventilation plate of the ventilation cover. The efficient protecting mask has the advantages that surface treatment is performed on the nonwoven cloth, so that physical adsorption efficiency of the nonwoven cloth is maintained while the electrostatic adsorption effect is improved without changing breathability; electric charge generated on the surface and high voltage between the friction pole plates have a bacterial killing and inhibiting effect, and the efficient protecting mask has a remarkable technical effect.

Description
