Waterproof principle of raincoat: there are more and more materials and styles of modern raincoat, but no matter how to change, raincoat has a nature that has never changed, that is, rainwater droplets will quickly gather into a small droplet on it and flow away, which is the reason why raincoat is waterproof.
When a drop of liquid falls on a solid surface, the liquid will have two different states depending on the attraction between molecules of different materials and the attraction between molecules within the liquid. When the molecular attraction between the liquid and the solid is less than the attraction of the molecules inside the liquid, the droplets tend to shrink into a small droplet on the solid surface; when the molecular attraction between the liquid and the solid is greater than the attraction of the molecules inside the liquid, the droplets tend to spread flat on the solid surface. For the former phenomenon, physicists call it "no infiltration", such as mercury drops on the glass plate, while the latter phenomenon is called "infiltration", such as water drops on the glass plate. Rain falls on the surface of the raincoat is a non-wetting phenomenon, because the attraction of rubber molecules to water molecules is far less than the attraction between water molecules, and water molecules prefer to gather together and roll down the raincoat. At the same time, there are many small holes in the raincoat fabric, but because the rain does not soak the rubber, water molecules are difficult to pass through the raincoat fabric from these small holes, and these small holes do not play a role in organizing air molecules, which ensures the breathability of the raincoat. Since the key to rainproof raincoat is on the rubber-like cloth surface, the raincoat should also pay special attention not to damage the waterproof layer of the cloth surface when storing it, so as to avoid sharp objects scratching the raincoat. There are two other things that need special attention. One is that the raincoat should be avoided to dry in the sun as much as possible after cleaning to avoid aging of rubber. Rubber is a polymer material, it has a lot of atomic groups and unsaturated chemical bonds, and it is easy to react with various components in the air, such as oxygen, and this reaction is irreversible; second, the raincoat should not be stored with objects such as grease, so as not to pollute the raincoat. It is difficult to wash the raincoat if the raincoat cloth is dirty.
