Abstract:

The structure of Triton X-100/n-C10H21OH/H2O lamellar liquid crystal system was determined by small angle X ray diffraction and 2H NMR. The lubrication properties of the lamellar liquid crystal with different composition were investigated under the high speed ring block wear tester. The results showed that the order parameter of lamellar liquid crystal decreased with increasing of water content, and increased with Triton X-100 content. The lubrication of the lamellar liquid crystal decreased with increasing of water content and increased with Triton X 100 content.

Key words: Lamellar liquid crystal, 2H NMR, Triton X-100, 1-decanol, Lubrication
