Abstract

An electrostatic adsorption mask is provided. The mask comprises two straps, a mask body, a filtering layer and a tiny power. The filtering layer is located in the mask body and comprises a first carbon nanotube layer, a second carbon nanotube layer and an insulated porous layer. The insulated porous layer is located between the first carbon nanotube layer and the second carbon nanotube layer. The first carbon nanotube layer and the second carbon nanotube layer are electrically coupled with the tiny power. An electric field is existed between the first carbon nanotube layer and the second carbon nanotube layer.
