An antimicrobial porous substrate and a method of making and using the same

摘要

A method of preparing an antimicrobial air filter comprising the steps of: soaking a porous material in a silver nanoparticle colloid; and coating the porous material embedded with silver nanoparticles with a silane quaternary ammonium polymer such that the loss of silver nanoparticles is reduced. The resultant filter may be used in an air treatment device.
