ION-TRAPPING SHEET, ION-TRAPPING MODULE, AND DEVICE FOR SUPPLYING CLEAN AIR

摘要

A sheet that uses inexpensive materials and is capable of trapping ionic substances in the air is provided. An ion-trapping sheet (1) has a conductive granular material (12) dispersed in an insulator (11), and a portion of the conductive granular material (12) is exposed at the surface of the insulator (11). When the ion-trapping sheet (1) is placed in air in which ionic substances in which either positive ions or negative ions predominantly exist, the ionic substances get trapped by the granular material (12) exposed at the surface of the insulator (11). As a result, an electric field forms at the surface of the sheet, regulating the direction of movement of the ionic substances that scatter in the air.
