【摘要】 本文研究了芳香酯类和苯基环乙烷类液晶的二元和多元混合体系。探讨了分子结构对液晶混合体系稳定性的影响和液晶混合体系的热力学性质。认为为了获得稳定的宽向列相范围的液晶混合体系应选择熔点低、熔融热焓小和结构相类似的液晶化合物。影响液晶混合体系稳定性的其它因素也作了讨论。更多还原

【Abstract】 The binary and multi-component mixed systems of aromatic ester and phenylcyclohexane types of liquid crystal were studied in this paper. The in. fluence of molecular structure on the stability of liquid Crystalline mixed systems and their thermodynamic propoty were discussed. It is found that liquid crystalline compounds with low-melting point, small melting enthalpy and similar structure should be selected in order to obtain stable liquid crystalline mixed systems with broad nematie phase range. Other factors affecting the stability of liquid crystalline mixed systems were also discussed.更多还原
