Title: AIR FILTER MEMBRANE FOR PREVENTING SMOG AND HAZARDOUS GAS AND MANUFACTURING METHOD AND USE THEREOF
Abstract:
Provided are an air filter membrane for preventing smog and hazardous gases and a manufacturing method and a use thereof. The air filter membrane comprises a nanofiber membrane made of a nanofiber and having a two-dimensional or three-dimensional web structure. The nanofiber membrane can be a membrane made of a high-molecular polymeric nanofiber and manufactured by means of an electrospinning process. The nanofiber membrane can be intercalated with an organic or inorganic additive capable of adsorbing hazardous gases in the air and providing a color response and/or a photocatalyst capable of degrading the hazardous gases by means of photocatalysis. The air filter membrane is applicable to air cleaning apparatuses such as a window screen, a mask, and a filtering screen.
