Great accomplishments in the field of microelectronics, especially intense in the last decade, began to awaken in people an ever greater thirst for a comfortable environment with amazing things. Aesthetics and power intertwined in an ephemeral manifestation of the human mind - the world was shown a multifunctional phone with a touch control panel, the screen of which received an oleophobic coating. The amazing substance and the ingenious simplicity of the invention will be discussed in this article.
A bit of biology and a little bit of physics
It was one of the features of human physiology that served as a kind of impetus to apply a substance whose properties would prevent the appearance of fatty traces on the surface of the touchscreen. After all, it's no secret to anyone that a smooth base, and even having certain mirror properties, is an incredibly easily soiled material. The oleophobic coating solved all the problems. The touch screen has acquired a serious enough protector that can easily preserve the aesthetic beauty and effective practicality of the display's color reproduction.
"Heroine" of the story -"Mistress Chemistry"
So, what is an oleophobic coating and what components does the “miraculous” substance consist of? In order not to be introduced into the terminology, let's just say that this is a kind of substance, which is based on: alkylsilane (organic hydrotrioxide), silicone - polyorganosiloxane polymers (organosilicon) and a solvent (as a binder).
However, a film only a few nanometers thick is capable of effectively repelling the multiple “tactile attacks” of our fingers. That is, the above spraying serves as a natural obstacle to fat in any of its manifestations. By the way, the chemical composition of a human print is nothing more than an aggressive environment, which has in its composition a fairly serious arsenal of various substances: several types of acids, ammonia, s alt and phosphates. So sweaty hands are “stress” for the oleophobic coating. However, everything has its limits, and the protective properties of spraying are no exception to the rule. However, more on that in the next paragraph.
What kills the oleophobic coating?
The main culprit of the destruction of the protective layer, of course, is considered to be mechanical impact. And the intensity of using a device that has an “anti-grease” coating is far from a creative force. However, all the above reasons are “nothing” compared to aggressive environments, which often become “saviors” in the hands of a person who thoughtlessly tries to wipe off an ink stain withtouch screen of an expensive device. Practice shows that at first glance, "innocent substances", sold under the guise of "superfood" effectively cleaning the oleophobic coating of the screen from any contamination, are actually dangerous liquids that contain alcohol or its derivatives or various solvents. Only after some time, the owner of a phone or tablet will pay attention to the fact that fingerprints have become “with progressive strength” fixed on the touch screen of their favorite device. And yet, for those whose experience was "savory", there is a way out.
Non-manufacturing spraying, or Fool yourself (Chinese reducer)
There is more than enough information on the network on a given topic. There are an incredible amount of substances imitating the protective layer on the market today. For your information, even an expensive spray can not guarantee factory quality (often promised in the annotation to the product), and even more so the durability of the layer obtained by spraying, rubbing or instillation. In the best case, you will get a frosted mist on the glass, or you will achieve a grease-repellent protection with a daily validity. Common sense should make you doubt the "miracle recipes", and life experience should require a detailed study of the essence of the issue: oleophobic coating - what is it? Dear readers, do not be deceived, because the technology of applying a protective layer is a complex chemical process of a production type. By the way, not every patent is made public (meaning an improvedspray type from Apple). Agree - this example is worthy of reflection. However, as promised, there is still an effective way.
Simple, fast, reliable and cheap
A protective film, of course, will not save your device from "signs of personality" (fingerprints), but its use will certainly have a positive effect on the presentable condition of the front of the device. In any case, you can wipe the display without fear of damaging the oleophobic coating. A high-quality film will protect your touchscreen from scratches and abrasions, and the small price of the accessory will not become an obstacle in order to re-replace the element protecting it from damage. It should be noted that many manufacturers have long mastered the technology of applying a grease-repellent composition to polymer products. So for owners who have lost the factory protective layer, and those people whose electronic components were not originally "oleophobes", such an alternative is really an ideal option to significantly affect the degree of protection of the device, as well as increase the level of comfort when using it.
Summing up
As you understand, do-it-yourself oleophobic coating can be unknowingly destroyed, but now you know that there are some possibilities for restoring the protective layer. So don't be upset if you made an operational mistake in the past tense… Alas, this is how a person was created, although learning from other people's flaws is much more painless. Be wise and protect your device from"obesity".
