Abstract
In a photocatalytic facial mask and a method for manufacturing the photocatalytic facial mask, the facial mask includes an inner layer, an outer layer, and a functional filter layer. The functional filter layer is disposed between the inner layer and the outer layer. The functional filter layer includes a photoactive layer, the photoactive layer includes a photocatalytic fiber having a core-shell structure, and the core-shell structure includes a core having a polymer fiber and a shell having a photocatalyst disposed at the core.
Claims14
A facial mask comprising:
- an inner layer;
- an outer layer;
- and
- a functional filter layer disposed between the inner layer and the outer layer,
- wherein
- the functional filter layer includes a photoactive layer, the photoactive layer includes a photocatalytic fiber having a core-shell structure,
- the core-shell structure includes a core having a polymer fiber and a shell having photocatalyst disposed on the core,
- the shell includes a first sheath layer having zinc oxide directly on the core and a second sheath layer having titanium dioxide on the first sheath layer,
- the first sheath layer has a thickness of 1 nm to 60 nm and the second sheath layer has a thickness of 0.1 nm to 30 nm, and
- the zinc oxide has a wurtzite structure and the titanium dioxide has an amorphous structure.
A method for manufacturing a facial mask comprising:
- coating photocatalyst on a surface of a polymer fiber, to form a photoactive layer including a photocatalytic fiber having a core-shell structure;
- forming an electrode on a surface of a textile and attaching a light source, to form a light irradiation layer;
- combining the photoactive layer and the light irradiation layer with each other, to form a functional filter layer;
- and
- inserting the functional filter layer between an inner layer and an outer layer of the facial mask,
- wherein
- the core-shell structure includes a core and a shell,
- the shell includes a first sheath layer having zinc oxide directly on the core and a second sheath layer having titanium dioxide on the first sheath layer,
- the first sheath layer has a thickness of 1 nm to 60 nm and the second sheath layer has a thickness of 0.1 nm to 30 nm, and
- the zinc oxide has a wurtzite structure and the titanium dioxide has an amorphous structure.
