| 摘 要： | 溶致液晶是两亲分子有序组合体的一种形式.与表面活性剂相比,高分子溶致液晶的研究开展较少,其中以主链型溶致液晶为主,而侧挂型支链高分子溶致液晶报导极少[1-3],但含有离子的不同烷基侧链的高聚物在溶液中自织组成液晶的规律性和性质的研究,在基础理论和应用方面皆有重?..

| Abstract: | The formation and structure of lyotropic liquid crystal of poly(sodium sulfoalkyl methacrylates)(PSSRMA)with different alkyl side chain length were studied.It is showed that the lyotropic liquid crystal could be formed for PSSRMA H-2O system.The d spacings of these polymers are in the range of 16.35-12.26 nm,which are much more than those formed by ordinary amphiphilic molecules.The micelles made up of single chain of PSSRMA polymers were arranged in order of hexagon or lamella to form lyotropic liquid crystal phase .The shorter the side chain of the PSSRMA,the longer the d spacing of the formed liquid crystal and vice versa.It is supposed that the electrostatic repulsion between two neighboring charged groups will be stronger for the shorter side chain due to a closer molecular arrangement,making the polymer chain extending and less flexible. |
