摘要
Provided herein are electret-MOF filter embedded with particles derived from metal-organic frameworks (MOF) and their methods of manufacturing. The methods of manufacturing the electret-MOF filter can include suspending MOF particles in a solvent to form a MOF particle mixture, contacting a charged polymeric fibrous web with the MOF particle mixture, and coating the charged polymeric fibrous web with the MOF particles by flowing the MOF particle mixture through an inverse side of the polymeric fibrous web. The disclosed coating method can deposit MOF particles uniformly, without formation of films at interstitial spaces between fibers. The electret-MOF filter can simultaneously remove fine particulate matters (PMs) and hazardous gaseous pollutants (including volatile organic compounds (VOCs)) with high particle holding and gas adsorption capacities, and with very low air resistance.
