| 1. | Preparation and study of the blood compatibility of cholesteryl liquid crystal composite membranes 胆甾醇液晶复合膜的制备及血液相容性研究 |
| 2. | For ten samples synthesized , six ones exhibit cholesteryl liquid crystal behaviors and four ones are not 合成的10个胆甾醇酯样品中, 6个具有液晶性, 4个不具有液晶性。 |
| 3. | The synthesized liquid crystal samples as a component were mixed with commercial cholesteryl liquid crystals to prepare thermochromatic liquid crystal mixture , respectively 然后将合成的胆甾型液晶与几种商品化的胆甾型液晶,进行混合液晶的调配与显色示温试验。 |
| 4. | The cholesteryl liquid crystal mixture was microcapsulized by complex coacervation method using gelatin and acacia as membrane materials . the effects of the concentr ation and quantity of arabic gum on the microcapsule particle size and color showing were also studied 最后,采用以明胶?阿拉伯树胶为囊壁材料的复凝聚法对配制的显色示温混合液晶进行了微胶囊化处理,并着重讨论了阿拉伯树胶的浓度及用量对液晶微胶囊粒度及显色效果的影响。 |
| 5. | Phenyl group introducing to cholesteryl ester molecules can enhance the phase transition temperatures of the liquid crystals and their stability . an increase in the chain length for cholesteryl dicarboxylate samples reduced stability of liquid crystal phases . while coattail - like structures on the ester group of the molecules have an adverse effect to form cholesteryl liquid crystal phase 化学结构对液晶性的影响表现为:分子中引入苯环刚性结构可以提高液晶的相变温度和稳定性;脂族二羧酸胆甾醇酯中脂肪链的长度增加会降低液晶的稳定性;而末端含有燕尾结构则对液晶态的形成产生不利影响。 |
