摘要:
A manufacturing method of a mold includes the steps of: providing an aluminum base in the shape of a hollow cylinder which is made of a Al—Mg—Si based aluminum alloy, the aluminum base being mechanically mirror-finished; performing a frosting treatment on a surface of the aluminum base with an aqueous solution which contains a salt of hydrogen fluoride and ammonium; thereafter, forming an inorganic material layer on the surface of the aluminum base and forming an aluminum film on the inorganic material layer, thereby forming a mold base; and alternately repeating anodization and etching on a surface of the aluminum film of the mold base, thereby forming an inverted moth-eye structure which has a plurality of micro recessed portions.
摘要:
A sterilization filter includes a synthetic polymer film, the synthetic polymer film having a surface which has a plurality of first raised portions, a two-dimensional size of the plurality of first raised portions being more than 20 nm and less than 500 μm when viewed in a normal direction. The synthetic polymer film is arranged in a predetermined shape. In the arrangement of the predetermined shape, an inclination of a normal to the surface varies depending on a position over the surface, and an inclination of a normal to a surface opposite to the surface varies depending on a position over the opposite surface. At least part of the surface is capable of coming into contact with a gas or liquid.
