'Once we have found a suitable liquid, we select solid materials that are promising to adhere to the client’s surface and that will form a suitable porous structure. The firm said: 'First, we identify liquids that are compatible with the chemical and physical properties of our client’s product. The coating can also be made up of different materials, depending on the application.įor example, when fitted inside ketchup bottles the liquid is plant-based, while other non-food stuffs can use non-edible chemicals. The solid surface is made up of spaces that are sufficiently close to each other to contain the impregnating liquid and the liquid is held in place within the texture, creating a permanently slippery surface.Īs a result, the ketchup, detergent or other product slides on the liquid layer, in a so-called 'liquid-to-liquid interface'.Īnd by changing the material used, and the structure of the coating, the researchers can also control the the speed at which liquids slide over the surface. The surface (illustrated) is made up of spaces that are sufficiently close to each other to contain the impregnating liquid and keep it in place
