Laser Diffractions in Lyotropic Liquid Crystal Formed by Liquid Dishiwash

We demonstrated that a lamellar phase of lyotropic liquid crystal formed by liquid dishwash could assemble themselves into crystal droplets when their isotropic phase was slowly changed into lamellar phase on the glass substrate. Characterization by means of polarized optical microscopy showed that a pattern of liquid crystal droplets was developed in the thin films formed by liquid dishwash. Our laser light diffraction experiments confirmed that these liquid crystal droplets could effectively diffract the incident red light from a helium-neon laser. On the basis of the Fraunhofer diffraction equation, we derived for the diameter of liquid crystal droplets. The diameter of liquid crystal droplet is 42.517 m, and almost agreement with the graph of polarized optical microscopy.

The laser diffractions phenomenon of surrounding bubbles of lyotropic liquid crystal formed by sodium dodecylsulfonate were investigated with polarized optical microscope and helium-neon laser, respectively. The eleven orders of diffractions can be observed when a beam of helium-neon laser is perpendicularly incident on the surrounding bubbles of lyotropic liquid crystal formed by sodium dodecyl sulfonate. The wavelength of the incident light is 633nm. And we have calculated the periodicity, p, of the grating was 0.211mm, and the small diffraction angle was 0.1146o. So we have simulated the microstructure of surrounding bubbles in the lyotropic liquid crystal formed by sodium dodecyl sulfonate.

The Difference

Periodically birefringent thin films growing out of the isotropic phase of the banana-shaped liquid crystal 1,3-phenylene-bis (4-butoxybenzyldiamine) were investigated with polarized optical microscopy. The gown thin films of the periodic modulation of the birefringent index self-assembled by the banana-shaped LC molecules were attributed to the difference of the molecular composing structures. Further the driving forces of the banana-shaped molecular self-assembly were discussed.

Cross Structure

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.

This paper focused on synthesizing the surfactant lyotropic liquid crystals (LLCs) through mixing the coconut diethanol amide (6501), primary alcobol ethoxylate (AEO9) and water. The LLCs phases formed in the ternary system are thoroughly investigated by polarized optical microscopy (POM). The obtained LLCs were characterized by XRD and SEM in order to analysis the texture, structure and the transformation. In addition, the LLCs have been applied in the preparation of TiO2nanoparticles in our research. The obtained TiO2powder were characterized by XRD and SEM, more importantly, the results showed that the LLCs are effective in the process of synthesizing TiO2nanoparticles.
