[0040] figure 1 is a configuration diagram of a filtering device for explaining the first embodiment of the present invention.

[0041] refer to figure 1 , the filtering device 10 of the first embodiment of the present invention includes a filter 11 in which a plurality of crystalline nanowires are regularly or irregularly arranged to have empty spaces existing between corresponding nanowires. At this time, the filter 11 may also comprise a molecular material filling some or all of the empty spaces between the nanowires arranged in a crystalline state.

[0042] A nanowire film composed of a plurality of nanowires constituting the filter 11 can be formed over a wide range of possible surface areas. For example, nanowire films can be formed to have 2 , greater than 1cm 2 , greater than 10cm 2 , greater than 1m 2 , and functional areas of even larger or smaller areas.

[0043] A nanowire film comprises a plurality of individual nanowires positioned in close proximity to ...

Abstract

There are provided a nanowire filter, a method for manufacturing the same, a filtering apparatus having the same, and a method for removing material adsorbed on the nanowire filter. The filtering apparatus includes: a filter having a supporting member and a plurality of nanowires supported on the supporting member and arranged in a crystallized state; and a body into which the filter is inserted and secured, and which has an inlet for guiding an introduced fluid to the filter and an outlet for discharging the fluid filtered through the filter to the outside.

Description

technical field [0001] The present invention relates to filters, and more particularly to nanowire filters, methods of making the same, filtration devices having the same, and methods of removing materials adsorbed on the nanowire filters. Background technique [0002] Hazardous organic substances produced as a result of industrialization, particulate hazardous materials and hazardous organic substances used in new buildings like new houses, gases that are fatal to the human body required in semiconductor processes, carcinogens found in smoking or in the air or at construction sites etc., have a great impact on human life and cause shortening of human life span. [0003] The devices that filter out these basic hazardous organic materials and gases, particles, etc. are filters. As these filters, HEPA (High Efficiency Particulate Air) filters and charcoal filters have been used. HEPA filters are used to filter particles from the air. Charcoal filters are used to filter orga...
