“Thermotropic liquid crystal”(熱緻液晶)是一種在特定溫度範圍内呈現液晶态的物質,其特性介于固态晶體與液态之間。以下是詳細解釋:
基本定義與特性
熱緻液晶由單一化合物或少數化合物混合物形成,僅在特定溫度區間内表現出液晶相。它兼具液體的流動性和晶體的各向異性,例如分子沿特定方向有序排列,導緻光學、電學性質的各向異性。
分類與對比
合成與應用
通過熔融縮聚法可合成熱緻液晶共聚酯(如含PET的共聚酯),用于增強材料性能。例如,作為增強纖維改善熱塑性塑料的機械強度,或用于環氧樹脂增韌。
物理化學性質
具有雙折射、電光效應等特性,可通過外場(熱、電、磁)調控分子排列,適用于顯示技術、傳感器等領域。
熱緻液晶是溫度敏感型功能材料,其獨特的相變行為與可調控性質使其在工程塑料、光電設備等領域有重要應用。

名詞
熱緻動液晶是一種特殊的液晶體系,它能夠對溫度的變化做出響應,從而發生相變。
英式發音:[θɜːməʊˈtrɒpɪk ˈlɪkwɪd ˈkrɪstl]
熱緻動液晶是一種重要的材料,在液晶顯示器、光學器件等領域都有廣泛的應用。
液晶是一種介于固體和液體之間的物質,在特定的溫度範圍内表現出一些特殊的物理性質。熱緻動液晶是一類具有特殊物理性質的液晶體系,它能夠對溫度的變化做出響應,從而發生相變。一般來說,熱緻動液晶具有兩種不同的相,即向列相和膽甾相。當溫度升高時,向列相會發生相變,由向列相轉變為膽甾相。而當溫度下降時,膽甾相會發生相變,由膽甾相轉變為向列相。這種相變現象使熱緻動液晶成為一種重要的材料,在液晶顯示器、光學器件等領域都有廣泛的應用。
