Many bacteria and viruses are lurking in the daily environment, especially in populous environments such as hospitals, public areas, and schools. In addition, the large-scale use of touch-sensitive products today is more likely to become a breeding ground for microbes and viruses such as bacteria and viruses. In particular, the touch panel installed in a public place has many users and is frequently used, and is more likely to be a hotbed for the spread of bacteria or microorganisms.

Taking a touch panel as an example, since the touch is a user inputting an instruction or performing an operation by directly touching the surface of the panel, not only the bacteria on the user's hand may adhere to the surface of the panel due to contact, dust of the user's finger or The oil stains also adhere to the surface of the touch panel, leaving fingerprints or marks, which affect the appearance or operation of the touch panel. For sensitivity.

However, the foregoing method needs to be applied to the antibacterial layer 12 and the anti-fingerprint layer 13, respectively, and the manufacturing process cannot be simplified. Further, since the antibacterial layer 12 and the anti-fingerprint layer 13 are sequentially applied, the antibacterial property of the object body and Anti-fingerprint performance is known to those skilled in the art to be most affected by the surface properties of the object. Therefore, the aforementioned antibacterial property is apparently affected by the anti-fingerprint layer 13 formed on the anti-bacterial layer 12. Therefore, how to provide the superior antibacterial and anti-fingerprint properties of the surface of the article is a positive direction for the relevant industry.

Accordingly, it is an object of the present invention to provide a film forming method for forming a functional film layer having both antibacterial and anti-fingerprint functions on the surface of an object.

Specific example

First material to be plated

3-aminopropyltrimethoxysilane was added to IPA (isopropanol, Isopropylalcohol) with a water content of 0.01%, and the reaction monomer was subjected to hydrolysis; 0.1 wt% of nitric acid was further added. The reaction monomer after hydrolysis is subjected to condensation reaction. After the reaction is completed, 1 wt% of zinc ions are added and then concentrated, and the cerium oxide (SiO ₂ ) particles are blended and dried together to obtain the positively charged The polyaminohaloxy compound powder particles are obtained to obtain the first material to be plated.

Characteristics and antibacterial and anti-fingerprint effects.

Anti-fingerprint features:

The contact angle and surface energy are indicators of the pro- and hydrophobic properties of the material itself. The contact angle is related to the hydrophobicity of the surface. The greater the contact angle between the substance and the water droplet, the higher the hydrophobicity, so the dirt and grease are not easily adhered; The smaller the contact angle between the substance and the water droplet, the higher the hydrophilicity. In addition, when the surface energy is larger, the greater the ability of the surface to adsorb liquid, the larger the liquid adsorption area, resulting in smaller surface contact angles, and dirt and grease are more likely to adhere. The present invention therefore indicates the anti-fingerprint properties of the functional film layer by measuring the water contact angle of the functional film layer.

Contact angle measurement

The antibacterial anti-fingerprint element prepared in the above specific example was measured for the contact angle of the functional film layer with water by a water drop angle measuring instrument (repeated measurement 5 times) as an experimental group (groups 1 to 5). The contact angle of the glass substrate on which the functional film layer was not formed on the surface and water (repeated measurement 5 times) was used as a control group (groups 1 to 5). The measurement results are summarized in Table 1 below.
