Study on Amphiphilic Molecules’ Self-Assembling into Lamellar Phase Process

Amphiphilic molecules self-assemble lamellar phase process in lyotropic liquid crystal formed by liquid dishwash was investigated with optical microscopy as concentration increases from its isotropic phase to its lamellar phase. We demonstrated that liquid dishwash molecules could assemble themselves into lamellar phase when their concentration increases between one pieces of glass substrate. We discussed the formative processes of Maltese-cross structure and phase transition from isotropic to lamellar phase.
