综述了液晶离聚物的分子设计与液晶热性能的关系,一般主链液晶,离子在链中浓度增加,玻璃化温度(Tg)和熔点(Tm )下降;离子在端基,对Tg 和Tm 影响不大;离子对侧链液晶的影响,取决于主链的柔顺性和离子在链中的位置等。一般情况下,无论对主链还是侧链液晶离聚物,随着离子在链中浓度增加,液晶相向各向同性液体转化温度(Ti)降低。
The relationship between molecular design and liquid crystal thermal properties of liquid crystal ionomer is reviewed. The main chain liquid crystal and ion concentration increase in the chain, while the glass transition temperature (Tg) and melting point (Tm) decrease. At the end groups, Little effect; ion pairs of liquid crystal side effects, depending on the flexibility of the main chain and the ion in the chain position. In general, both the main chain and the side chain liquid crystal ionomer, as the concentration of ions in the chain increases, the liquid crystalline phase isotropic liquid transition temperature (Ti) decreases.
