Abstract: The interlayer spacing of lamellar liquid crystal decreased with increase of the weight ratio of decanol/SDS at constant solvent content in the system of SDS/decanol/glycerol, but increased in system of SDS/decanol/formamide. At a constant weight ratio of decanol/SDS, tbe interlayer spacing decreased when formamide was used as solvent instead of glycerol. These results are related to the effects of hydrogen bond formed between solvent and SDS, decanol and the similarities of glycerol and decanol for the penetration of the solvent in to the lamellar liquid crystal.

Key words: Surfactant, Non-aqueous lamellar liquid crystal, Low angle X-ray
