烷氧基苯甲酸类化合物相变的起伏织构

Undulation textures at the phase transitions of some alkyloxybenzoic acids

A. Sparavigna, A. Mello, G. Massa

摘要:

我们观察到的4,n-烷氧基苯甲酸(nOBAC)酸系列的一些化合物,在近晶相和各向同性相之间的过渡和近晶相和近晶相之间的起伏近晶纹理。所研究的化合物是12 OBAC、16 OBAC以及12-和16 OBAC的二元混合物。这些起伏是一种常见的纹影纹理。在二元混合物的情况下,也观察到有趣的指纹图案。

英文摘要:

We observed undulated smectic textures for some compounds of the 4,n-alkyloxybenzoic (nOBAC) acid series, at transitions between the smectic and the isotropic phase and between the smectic and nematic phase. Studied compounds were 12OBAC, 16OBAC and a binary mixture of 12- and 16OBAC. The undulations are dressing a usual Schlieren texture. In the case of the binary mixture, an interesting fingerprint pattern is observed too.
