摘要：

A number of lyotropic lamellar liquid crystalline phases have been formulated using the surfactant cetyltrimethylammonium chloride in the solvents ethylene glycol and glycerol, using decanol, dodecanol, oleic acid, and oleyl alcohol as cosurfactants. The lamellar phases and their existence range were characterized using optical microscopy, X-ray diffraction and differential scanning calorimetry. The purpose of the exercise was to test these lamellar phases as potential lubricants by measuring their coefficients of friction in metal to metal contact. The results indicate that some of the samples have coefficients of friction similar to or better than selected commercial oils.
