摘要

用偏振光方法对纤维素和一些简单酯和复杂酯在不同溶剂中的液晶结构进行了温度浓度研究。确定了过渡到液晶相的临界浓度、胆甾螺旋的螺距和棒状结构域的参数。结果表明，所研究的各向异性溶液的结构都可以用具有格伦扎诺夫织构的胆甾体液晶的无序排列域系统来表示，不同溶液的胆甾体螺旋扭的大小和步长不同。

Temperature–concentration conditions for the formation of liquid crystalline structures in solutions of cellulose and its derivatives

Temperature-concentration studies of the liquid crystal structure of cellulose and some simple and complex esters in various solvents have been carried out using polarization-optical methods. The critical concentrations for the transition to the liquid crystalline phase, the pitch of the cholesteric helix, and the parameters of the rod-like domains, were determined. It has been shown that the structure of all studied anisotropic solutions can be represented by a system of chaotically arranged domains of cholesteric liquid crystals with grunzhanov textures, which differ in the size and the step size of the cholesteric helix twist for different solutions.

期刊介绍： Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including: polymer synthesis; polymer reactions; polymerization kinetics; polymer physics; morphology; structure-property relationships; polymer analysis and characterization; physical and mechanical properties; electrical and optical properties; polymer processing and rheology; application of polymers; supramolecular science of polymers; polymer composites.
