The preparation of silver sulfide nanoparticles in lamellar liquid crystal and application to lubrication

The silver sulfide (Ag2S) nanoparticles were prepared by the reaction of AgNO3 and Na2S in the lamellar liquid crystal (LLC) formed by Triton X-100, n-C10H21OH and H2O. The size of the particles is about 2-3 nm. The existence of Ag2S nanoparticles can improve the lubrication of the lamellar liquid crystal.
