Scientists Develop Super-Slippery Material

Hugh Pickens writes writes "Anyone who is partial to ketchup with their food will know how difficult it is to get the final dregs from the bottle but now the Telegraph reports that scientists have created one of the most slippery materials ever that promises to result in new self-cleaning surfaces that never get dirty, could be used to coat the inside of bottles and jars to help consumers get all of the food inside, or in the energy industry for making oil flow more efficiently through pipes. Professor Joanna Aizenberg, a materials scientists at Harvard University, was inspired by the carnivorous Nepenthes pitcher plants, which has a highly slippery surface at the top of its flute-shaped leaves so that insects tumble down into the digestive juices contained inside. The new material, known as a Slippery Liquid Infused Porous Surface or SLIPS boasts a rare trait called "omniphobicity", which means it can repel both water and oily materials. "If we used substance like ours to coat the inside of bottles, it would be possible to get it all out," says Aizenberg. "The only problem may be that the sauce may come out a little too easily on to their food.""

For relatively low velocity, low density, high viscosity flows the pipe surface roughness does not matter.

Fluff technology advances fast but the real stuff that gets widespread adoption is a lot slower than our media tells us.

      It is REALLY hard to make a material which will resist corrosion from alkaline solutions as well as acid, heat , scratching , fracture and so on all at the same time. People that design satellites, space probes or nuclear reactors additionally have to deal with intense radiation that can alter the chemical properties.

      Then there is photo-damage. Many organic materials degrade under exposure to sunlight. You got oxidation to worry about, redox reactions with salts and other ionic compounds. If the material is porous then small molecules can diffuse into it and weaken it from the inside.

      Basically you will not be able to make a material I cannot find a way to dissolve or destroy. Granted, if you put something quite tough onto a very sensitive fabric, I may not be able to get rid of it without destroying the cloth. There's no need for super-slippery materials for this however.

Various diamond like carbon coatings have been used for things like rocker arms, cams, gears, and other sliding surfaces on race engines. Also there have been some people experimenting with various nitride compounds for places where DLCs won't work (that whole higher temperature iron thing) and some look promising. The other thing these compounds offer is that they are tough and don't wear anywhere near as much so it greatly extends the service life of the part.

    So, let me get this straight... a manufacturer is going to spend more money on a product so that consumers can go longer before buying the product again? Not sure what economic system they use where you live, but this isn't how things work in capitalism. One of the secrets here is to get consumers to use the product up faster without noticing its decreased effectiveness. For example, when toothpaste makers switched from tubes that dispensed the product in flat ribbons to round cylinders, or how toilet-paper manufacturers can make the squares just a little bigger each year.

    If anything, I'm surprised they don't make the inside of the bottle more sticky and then make the bottle opaque (like with mustard) so that you can't see how much product you're throwing away.

    Just a couple points I want to make:

    - Nowhere in the paper is there anything about using this stuff in ketchup bottles. I'm sure the researchers seized on this when they got interviewed as a simple way to explain lyophobicity to a general audience, the effect of which was to make "getting all the ketchup out of the bottle" the only thing anyone remembers. Typical.

    - As for the significance of the research, there has been a ton of work in the last, oh, say 10-20 years on superhydrophobic surfaces, which have texture on the scale of a few nm that prevents water or other high surface tension liquids from penetrating into these tiny cracks. The water drops energetically prefer to remain as spherical as possible and so the liquid is repelled. This doesn't work with low surface tension liquids like light oils because it would rather penetrate inside the texturing than stay in a roughly spherical drop. The neat advance in this work is the addition of a low surface tension liquid which is introduced into the textured Teflon or fluorinated silane surface and repels both water and oil. They can use lots of different chemicals for the liquid, so as they continue the research they will find that some resist high heat, others are bio-inert, etc etc. so there are many possible applications.

      Actually, the teflon tape doesn't stop the leaks. All it does is act as a solid, non-toxic lubricant that allows the threaded pipes to screw. The seal is made because the pipes, usually made of soft metals (copper, bronze), or plastic (for polypropilene, not PVC) deformates and creates a water-tight seal. A new pipe has sharp threads, a used one looks "rounded" or otherwise deformed.

      Adding more teflon tape to a loose thread won't seal it, the solution is to use some other kind of filler. While there are products (thread sealers) in the market nowadays, the old school way of doing it is with hemp fibers and asphalt paint. In fact, many thread sealers suggest adding a few strands of hemp to fill in the out-of-spec threads.

      Nevertheless, the best joint seal is no joint seal. That's why many builders prefer copper pipes, which come in rolls and you can minimize the amount of joints, which are soldered anyway - so they last forever. But plastic pipes are also great (and less reactive than copper) when thermo-fused: the end of each pipe is heated and they're pressed together to form what's effectively a single piece of pipe: https://www.youtube.com/watch?v=aq6vbi0nULg

      They also make accessories to make T-joints and plastic-metal unions (so you do metal-to-metal joins at the wall level).
