The present disclosure relates to a method for manufacturing an air filtration material, in which the porous metallic support is treated with at least one chemical agent to improve adherence of the electrospun nanofibers. The air filtration material obtained from such method comprises nanoparticle photocatalysts, wherein the nanoparticle photocatalysts are embedded in the electrospun nanofibers and part of the nanoparticle photocatalysts is exposed at the surface of the electrospun nanofibers through nanopores. An air filtration device, comprising the air filtration material, a UV LED and a power source. A method of using the air filtration material wherein an air flow passes through the air filtration material, wherein the air flow has a pollutant content before passing through the material, in order to decrease the air pollutant content. The nanoparticle photocatalysts inactivate or kill the pathogens when the device is in operation.

A polymer body includes a first thermoplastic polymer, and a second thermoplastic polymer. The first thermoplastic polymer and the second thermoplastic polymer form a continuous solid structure. The first thermoplastic polymer forms an external supporting structure that at least partially envelops the second thermoplastic polymer. A first flow temperature of the first thermoplastic polymer is at least 10° C. higher than a second flow temperature of the second thermoplastic polymer. The first thermoplastic polymer may be removable by exposure to a selective solvent.
