Organic substances such as phthalocyanine or melamine-isocyanuric acid complex are mentioned, and it is known that liquid crystal compounds can give a very low coefficient of friction when used as a lubricant (Gama Biasot. -Edited ACS Symposium Series 441 "Tribology and Liquid Crystalline State").

比して比較的高い摩擦係数を与えるという欠点を有す
る。Ordinary oils are chemically unstable, and there is a problem in reliability as a lubricant for a long period of time or under high temperature, and a chemically stable lubricant is required. In this case, an organic fluorine compound, so-called fluorine oil, is used as a lubricant. However, although fluorine oil is chemically stable, it has a drawback that it gives a relatively high coefficient of friction as compared with ordinary oils, that is, hydrocarbons and esters.

めに弗素油に対して、弗素油より摩擦係数の低い油類を
配合した場合には、油類は弗素油に溶解または分散する

ない。When an oil having a friction coefficient lower than that of the fluorine oil is mixed with the fluorine oil in order to make up for such drawbacks of the fluorine oil lubricant, the oil should be dissolved or dispersed in the fluorine oil. It is impossible to achieve the purpose of lowering the coefficient of friction by separating without any separation.

For example, when molybdenum sulfide is oxidized, it becomes molybdenum oxide, which acts as an abrasive to increase wear without acting as a lubricant, or may scatter other parts by scattering solid substances. However, liquid crystal compounds are chemically relatively stable, but when they are compounded in oils, they do not exhibit the low friction coefficient that liquid crystal compounds should originally give, and the higher friction coefficient than that of liquid crystal compounds,
That is, it only gives an intermediate value with the oils.
