Conventional technology

  Conventionally, the seriousness of the hygiene problem has risen with the rapid increase in the usage rate of smart devices such as touch-type displays (smartphones, tablet PCs, smart watches, etc.), and the interest in antibacterial activity has increased. However, the anti-fingerprint coating currently applied does not have an antibacterial function, and there is an urgent need to develop a technology capable of imparting an antibacterial function to a touch screen window, which is a part that the user often touches.

  Currently, a commercially available smartphone window (touch screen) is provided with a thin film (several tens of nm) anti-fingerprint coating (or antifouling coating). Anti-fingerprint coatings use fluorinated compounds to impart water / oil repellency properties to the surface, which lowers the surface energy and reduces fingerprint and external contaminants from the coated surface. It has the characteristics that the contact area is reduced, the sticking of contaminants is minimized, and the sticking can be well wiped off.

  In order to form such a thin film, a coating method called “vacuum evaporation” is almost used. However, coating (surface modification) using vacuum evaporation requires a target (coating agent) in a very short time. )), A high-temperature heat source is added and the coating proceeds. Therefore, the coating film quality is excellent, the amount of chemical loss is small, and nano-sized thin film coating that does not impair the optical properties is possible.

  Many antibacterial coatings using inorganic substances (Ti series) are known in the city, but most of them use the wet method. There are no pharmaceutical manufacturers with In the case of inorganic coatings using vacuum deposition, the ignition temperature is high, and there are restrictions on the base materials that can be coated (coating materials are sensitive to temperature-tempered glass, plastics, etc.). The surface is discolored, causing a problem that the optical properties are hindered.

  Patent Document 1 relates to a technology for developing and utilizing a vacuum deposition system that applies anti-bacterial nanotechnology. Here, the antibacterial effect is realized by using pasture materials (such as sharpener, harunire, ume). However, the antibacterial function is insufficient, and there is a problem that the sustainability is difficult to be maintained, and the functions such as water / oil repellency and slipping are difficult to be realized.

  Patent Document 2 discloses a technique for suppressing the growth of microorganisms by applying and coating a coating agent containing an antibacterial drug on the outer surface of a television, which also has water / oil repellency and slip properties. There is a problem that it is difficult to implement such functionality.

  Patent Document 3 discloses an antibacterial material characterized by forming a zinc oxide thin film on a glass substrate, plastic, or the like that can be used on the surface of a touch panel or a mobile phone, by a technique such as vacuum deposition or sputtering, and a method for manufacturing the same. Although disclosed, this also has a problem that functions such as water / oil repellency and slip properties are difficult to be realized, and there is a problem that optical properties are deteriorated by the metal thin film.
