A new approach to study interaction parameters in cyanobiphenyl liquid crystal binary systems
The phase transition of heptylcyanobiphenyl 7CB and pentylcyanobiphenyl 5CB liquid
crystals was investigated using the differential scanning calorimetry DSC technique. Then,
the phase transition of different compositions of 7CB/5CB binary mixture was studied to
determine the eutectic point. The phase diagram of mentioned binary system in 7CB mole
fraction of 0.45 at T= 273.45 K is in good agreement with that of predicted from Schroder–
van Laar equation. The thermodynamic excess functions and interaction parameters were …
