摘要: 发现某些含二维液晶基元的热致液晶高分子容易产生反向壁织构与含有高强度向错点(|S|大于1)的向列态纹影织构。这类液晶高分子的织构与形态学特点与含一维棒状液晶基元的其他液晶高分子不同。

Abstract: The observation of inversion walls and nematic schlieren textures with singularity of high strength in polymer samples is reported. The polymers are of the type with two-dimensional mesogenic units and flexible spacers in the main chain and all form a nematic liquid crystal phase above melting.

Key words: liquid crystal polymer, schlieren texture, disclination
