Dr. American Chinese invented the ultra-stainless liquid for medical equipment
Liu Tingyi, the inventor of the "super lyophobic" structure. (United States "World News" / Liu Tingyi provides According to the US "World News" report, Los Angeles has invented the "Superomniphobic" structure by UCLA Mechanical and Aerospace Engineering. Any material can pass the micro-nano like super non-stick liquid. The super-hydrophobic structure makes the surface "super-lyophobic" so that all liquids do not infiltrate into the material. The study was published in the journal Science and has applied for an international patent "transforming any material surface to a liquid surface". Dr. Liu Tingyi, one of the inventors of the "super lyophobic" structure, said that the concept of "super lyophobic" originated from the three-dimensional and crystal water droplets on the surface of the lotus leaf after rain, indicating that the surface of the lotus leaf is very hydrophobic and will not let The water drops infiltrated into the leaves. Many waterproof materials in life are composed of chemical structures. For example, clean glass can actually be attached to most liquids. When it rains, the water drops do not attach to the windshield of the car because the windshield has Apply a waterproof coating. Like the non-stick pans used today when people cook rice, the surface is coated with the concept of Telfoon chemical materials and micro-nanostructures. Some people have previously made "super-hydrophobic" and "super-oleophobic" surfaces. However, the fluoride liquid can completely infiltrate all existing chemical materials, rendering the previous technology using chemical coatings ineffective. The "super-lyophobic" surface of this invention does not require the use of a chemical coating, but a purely physical structure. In theory, any material can be blocked by various physical fluids as long as it is made of such a physical structure. Liu Tingyi said that the "super lyophobic" surface is composed of a micro-nano structure like many small umbrellas, only 5% is the surface of the material, and the other 95% is air. Despite this, the micro-nano structure effectively supports the inability of liquid to enter the space around the umbrella, making it impossible for liquid to penetrate the surface of the object. In scientific journals, they compare the differences between Teflon (chemical structure) and "super lyophobic" (pure physical structure). On the "super-lyophobic" surface, droplets of water, methanol, perfluorohexane (3M FC-72 electron fluoride) still have a three-dimensional shape like a pearl. However, on the surface of Teflon, water and methanol droplets are three-dimensional, but flatter, while perfluorohexane is a complete infiltration of Teflon surface in an instant, and no three-dimensional droplets are visible. "Superhydrophobic" is extremely versatile and is expected to contribute greatly to the development of medical devices. Since many medical devices are placed in the human body, after a period of contact with the living organisms in the human body, the equipment implanted in the body will be biodeposited. Liu Tingyi said that the concept is like when a ship is sailing on the sea, many creatures in the sea will secrete something to allow them to attach to the ship. Therefore, whenever the ship is on the shore, you can see many mosses or small creatures in the sea. In other words, "super lyophobic" medical equipment is expected to prevent biofouling on medical equipment in the human body.
