Abstract

The present invention relates to a membrane including a metal substrate layer and a CNT/chitosan nanohybrid coating layer, and an electrostatic dust collection system including the same. The membrane of the present invention has excellent electrical conductivity and is thus capable of efficiently collecting dust, even with a low current, and has excellent mechanical strength and is thus suitable for application in various types of electrostatic dust collection systems.
