Description

Antiviral film {ANTIVIRAL FILM}

The present invention relates to an antiviral film, and more particularly, to an antiviral film capable of achieving antiviral properties even without including an antiviral metal.

Recently, there have been reports of deaths due to novel virus infections such as SARS (Severe Acute Respiratory Syndrome), avian influenza, and COVID-19.

Currently, due to the development of transportation and the mutation of viruses, we are facing a crisis of a "pandemic" that spreads a virus infection all over the world, and urgent countermeasures are required.

In order to respond to this situation, development of antiviral agents based on vaccines is also hastily developed, but since vaccines have their specificity, only a specific virus can prevent infection.

Therefore, the development of an antiviral member which is effective against various viruses and bacteria and can exhibit sterilization and antiviral effect is strongly calculated|required.

As a means to solve these problems, there is a virus inactivation sheet using a composite containing an inorganic porous crystal supporting an antibacterial metal ion such as silver ion or copper ion inside a resin.

However, in the case of such a conventional virus inactivation sheet, there is a disadvantage that the sterilization and antiviral effect can be exhibited only when an antibacterial metal such as silver ion or copper ion is included.

Referring to Figure 1, the antiviral film (1) according to the first embodiment of the present invention, the base film (10); and a pattern layer 20 disposed on the base film 10 .

More specifically, the base film 10 is an inorganic material such as quartz or glass, polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polycarbonate (PC), polystyrene (PS), polypropylene (PP) ), polyimide (PI), polyethylene sulfonate (PES), polyoxymethylene (POM), polyether ether ketone (PEEK), polyether sulfone (PES) and any one selected from the group consisting of polyether imide (PEI) It may be made of a single plastic material, but the material of the base film is not limited in the present invention.

In addition, the pattern layer 20 corresponds to a pattern exhibiting super water-repellent properties, that is, in the present invention, through a pattern representing super water-repellent properties, antiviral properties of the antiviral film according to the present invention are to be implemented.

In general, superhydrophobic or superoleophobic properties are a field of surface modification technology, and the wetting angle when a liquid comes into contact with the surface of a solid by modifying the surface physicochemically It is a technique to make this 150° or more.

For example, super water repellency can be observed frequently through lotus petals existing in nature. Water droplets condensing or rolling down on the lotus petals are caused by nano-scale microscopic projections on the surface of the lotus petals.

That is, in the present invention, by arranging the pattern layer 20 exhibiting such super water-repellent properties on the base film 10, an antiviral film capable of implementing antiviral properties is to be provided.

Meanwhile, a specific example of the pattern layer will be described later.

In this case, the antiviral metal layer 30 may include at least one material selected from the group consisting of silver (Ag) and copper (Cu), however, in the present invention, the antiviral metal layer 30 ) is not limited.

Meanwhile, in the present invention, the base film 10 may have a micro-scale thickness, and the antiviral metal layer 30 may have a micro-to-nano-scale thickness. However, in the present invention, the base film 10 And the thickness of the antiviral metal layer 30 is not limited.

However, the antiviral film according to the present invention may be used attached to an object such as a button of an elevator, or a displayed display. It is preferably made of a transparent material so that the object can be visually confirmed, therefore, the base film is preferably a transparent material, and the antiviral metal layer is preferably a nano-scale thickness to achieve translucency.

For example, when the antiviral metal layer is formed to be less than or equal to 500 nm, the antiviral metal layer may achieve translucency.

In addition, in the present invention, the pattern layer may have a thickness of micro to nano scale.

At this time, for the same reasons as described above, it is preferable that the pattern layer 20 is also made of a transparent material, for example, an acrylic resin such as polyester acrylic, urethane acrylic, epoxy acrylic, polyether acrylic, or an epoxy resin. An epoxy-based resin may be used, but the material of the pattern layer is not limited in the present invention.

However, when the pattern layer is made of an opaque material, on the same principle as the metal layer, in order to achieve translucency of the pattern layer, it is preferable that the pattern layer has a thickness of a nanoscale.

Hereinafter, specific examples of the patterned layer according to the present invention will be described in detail.

3 and 4 are schematic schematic diagrams showing the shape of the patterned layer according to the first example of the present invention, and FIGS. 5 and 6 are schematic schematic diagrams showing the shape of the patterned layer according to the second example of the present invention. am.

First, referring to FIGS. 3 and 4 , the pattern layer 20 according to the first example of the present invention includes a convex portion pattern 21 ; and a concave portion pattern 24 having a lower step than the convex portion pattern 21 .

More specifically, the convex portion pattern 21 may include a column portion pattern 22; and a partition part pattern 23 continuously positioned with the column part pattern 22 .

The column part pattern 22 includes a first column part pattern 22a; a second column pattern 22b positioned adjacent to the first column pattern 22a; a third column pattern 22c positioned adjacent to the second column pattern 22b; and a fourth column pattern 22d positioned adjacent to the third column pattern 22c.

In this case, as shown in the drawings, the first column part pattern 22a to the fourth column part pattern 22d may be disposed to form a rectangular shape.

In addition, the partition pattern 23 may include a first partition pattern 23a connecting the first column pattern 22a and the second column pattern 22b; a second partition pattern 23b connecting the second column pattern 22b and the third column pattern 22c; a third partition pattern 23c connecting the third column pattern 22c and the fourth column pattern 22d; and a fourth partition pattern 23d connecting the fourth column pattern 22d and the first column pattern 22a.

Accordingly, one continuous convex part pattern 21 is defined by the column part pattern 22 and the partition part pattern 23 , and is partitioned by the convex part pattern 21 . The concave portion pattern 24 is formed in the region to be used.

However, since the concave portion pattern 24 may correspond to an empty space, it may be simply defined as a concave portion, and thus, in this case, the pattern layer 20 is sub-pattern 21; and a concave portion 24 having a lower step than the convex portion pattern 21 .

That is, in the present invention, the meaning of the concave pattern 24 is that a certain layer is formed in the concave pattern 24 region, or the concave pattern 24 is This is meant to include all cases where an empty space without a specific layer is formed in the area.

That is, FIGS. 5 and 6 relate to the patterned layer 20' according to the second example of the present invention, and as shown in FIGS. (not shown) may be arranged in a hexagonal shape, and thus, the concave part pattern 24' located inside the region partitioned by the convex part pattern also has a hexagonal shape. It can be confirmed that they are formed and placed.

Therefore, in the present invention, the shape of the one continuous convex part pattern and the shape of the concave part pattern positioned inside the region partitioned by the convex part pattern are not limited. .

In general, since most micro-to-nano-scale structures implementing the conventional super water-repellent properties have a column structure, they must be basically formed to have a high aspect ratio.

However, nanostructures having such a high aspect ratio initially exhibit superhydrophobic properties, but are tangled or lie sideways due to capillary force generated when water (or solution) in contact with the surface evaporates. There was a problem in that the superhydrophobic properties could not be continuously maintained.

However, in the present invention, one continuous convex part pattern 21 is defined by the column part pattern 22 and the partition part pattern 23 , and the convex part pattern 21 is defined. ) by forming a micro-to-nano-scale structure in which the concave pattern 24 is formed, capillary force generated when water (or solution) in contact with the surface evaporates ( capillarity), it is possible to provide a super water-repellent or super-oil repellent pattern capable of continuously maintaining the super water-repellent properties.

As a result, in the present invention, it is possible to provide an antiviral film capable of implementing antiviral properties through a pattern layer having excellent super water repellency or super oil repellency properties as described above.
