稳定的自由悬浮细丝的形成是某些液晶相的一个有趣的特点。到目前为止，人们对它们的结构和稳定性知之甚少。与独立的近晶薄膜类似，中间相的内部分子结构稳定了这些长径比为10(3)以上的宏观有序物体。本文报道了在不同的中间相中观察到弯曲型分子形成的近晶液晶纤维。我们的研究采用了几种实验技术，重点研究了纤维形成的力学和结构方面，如内部结构、稳定性以及机械和光学性质。
The formation of stable freely suspended filaments is an interesting peculiarity of some liquid crystal phases. So far, little is known about their structure and stability. Similarly to free-standing smectic films, an internal molecular structure of the mesophase stabilizes these macroscopically well-ordered objects with length to diameter ratios of 10(3) and above. In this paper, we report observations of smectic liquid crystal fibers formed by bent-shaped molecules in different mesophases. Our study, employing several experimental techniques, focuses on mechanical and structural aspects of fiber formation such as internal structure, stability, and mechanical and optical properties.
