Studies on binary mixtures of nematic liquid crystals made of strongly polar molecules with identical cores and antagonistic orientation of permanent dipoles

Dasari Venkata Sai, Tae Hoon Yoon, Surajit Dhara

We report experimental studies on optical (birefringence, $\Delta n$), dielectric $(\Delta \epsilon )$ and bend-splay elastic anisotropies ($\Delta K=K_{33}-K_{11})$ of a few mixtures of two nemat…
