Abstract:

This paper reports details of phase transitions of a new generation “Tertiary Liquid Crystal System” (TLCS). This TLCS was made with a mixture of 5CB, 6CB, and 7CB liquid crystals. The TLCS was run in DSC to find changes taking place in its heat flow as a function of time and temperature analyzed with Logger Pro. The sample of TLCS was run from -40 °C to 80 °C with a 20 °C/min ramp rate in DSC. It was observed that the TLCS shows two phase transitions on heating and one transition on cooling. All these transitions were found to shift when compared to their single members. The unique behavior of TLCS is that it never shows crystallization in cooling, even though the sample was cooled to -40 °C. This indicated an increase in its Nematic range, making it more useful in the Liquid Crystal Display (LCD) field.
