First Fundamentally New Lubricant in Decades

The world uses tens of millions of tons of lubricant every year, from the smallest part of a micro-precision instrument to the expansion rollers on the largest bridges. Most are oil based, though others use powders, and even metals, and it's been that way for decades.

That could be changing as the Fraunhofer Institute for Mechanics of Materials (IWM), Nematel GmbH, and Dr. Tillwich GmbH have developed a new class of lubricants that are based on liquid crystals instead of oil. According to Fraunhofer, this is the first fundamentally new lubricant developed in twenty years. Liquid crystals are an oddity of the chemical world that most people know from digital displays and television sets, but are actually found in everything from cell membranes to soapy water. As the name implies, a liquid crystal is a substance that is neither entirely a liquid, nor a crystal, but possesses the properties of both, such as a liquid that retains the structure of a solid crystal.

  For those wondering why this is a good lubricant this little blurb is worth while.

  When two surfaces move in opposite directions, the liquid crystal molecules between the two surfaces align themselves so that the frictional resistance is extremely low. This enables nearly frictionless sliding.

  What I wonder is how does it compare to other lubricants in things like film strength and breakdown under heat?
