EXTERNAL AFFECTED AREA PROTECTIVE MATERIAL

摘要

An external affected area protective material (20) capable of efficiently deactivating specified harmful substances allowed to be present in the affected area on the outside of a body by photocatalytic reaction, comprising a sheet (21) installed on the affected area and photocatalysts (26) held on the sheet in a light receivable state, the sheet further comprising a porous layer (25) having pores of such sizes that can receive exudate from the affected area and foreign matter mixed in the exudate, wherein one or more types of arresting substances (28) having a selective combining ability for one or more types of substances allowed to be deactivated by the photocatalytic reaction are desirably disposed in the porous layer at positions close to the photocatalysts.
