What is it about?
We report the results of our studies on optical and thermal properties of two com- pounds viz., cholesteryl linolenate and poly ethylene glycol exhibits very interesting liquid crystalline-induced lamellar smectic phases at large range of concentrations and temperature. The mixture with lower and higher concentrations of poly ethylene glycol (PEG) exhibits an Iso-N ∗ -SmA-SmE-Cry, sequentially when the specimen is cooled from its isotropic phase. But concentrations from 20% to 40% of the mixture exhibit a SmC ∗ phase. Different phases were observed in the mixture and are identified using X-ray and microscopic techniques. The temperature variation of optical anisotropy and helical pitch measurements are also discussed.
