Abstract

Electret is a dielectric material that can store charges for a long time and generate a permanent electric field without an external electric field.Electret fiber filter materials can efficiently remove fine particles in the air,and widely used in indoor and outdoor air pollution prevention and control.The principle of electret fiber filter material was introduced,and pointed out the research progress of electret fiber filter material from four aspects of electret process,electret material,charge attenuation and charge storage increase.The problems and future development trends of electret fiber filter materials were pointed out.
