摘要：
Antiferroelectric Liquid Crystals are the promising materials for applications. Binary mixture was prepared using compounds which do not exhibit antiferroelectric phase. Final mixture indicate wide antiferroelectric phase. Dielectric spectroscopy was performed to identify mesogenic phases. A very strong BIAS field influence on dielectric behavior was found. It is clearly shown that the strong DC field eliminates the anticlinic SmC(A)* phase in favour of synclinic SmC* one.
