A multi-layered nanofiber filter on a base material with enhanced heat resistance is manufactured by stacking heat resistant nanofibers in multiple layers by an electrospinning method in order to resolve low thermal stability, which is a flaw of the prior nanofiber filter. The multi-layered nanofiber filter on a base material is manufactured by stacking one nanofiber selected from nanofibers of polyacrylonitrile, polyether sulfone, polyimide, polyvinylidene fluoride, meta-aramid and polyamide which are heat resistant polymers on a meta aramid or cellulose base material; and continuously electrospinning inorganic polymer nanofibers on the heat resistant polymer nanofiber. Therefore, the functional filter, which has price competitiveness and can ensure high efficiency and heat resistance, is manufactured. |
