| 摘 要： | 以溶液共混法制备了壳聚糖与乙基纤维素的共混物．用大角Ｘ光衍射、ＤＳＣ和偏光显微镜等技术研究了体系的相容性和液晶性．结果表明壳聚糖与乙基纤维素有部分相容性．共混物中乙基纤维素溶致液晶的临界浓度与共混物组成无关，而液晶织构的出现却与共混组成有关．

| Abstract: | Solution blending was applied to prepare the blends of chitosan (Ch) and ehtyl cellulose (EC).The compatibility and liquid crystallinity of this system were studied by using the technique of WAXD, DSC and PM.There is partial compatibility between Ch and EC. The critical concentration of lyotropic liquid crystalline EC in blends was not dependent on the composition of blends, but the induction time of the appearance of liquid crystalline texture was related to the composition of blends. |
