摘　　要：聚合物共混体系(又称聚合物合金)兼具其相应组分的均聚物和共聚物的多种特征,甚至具有新的理想性能,从而成为了一种具有极高经济价值的新材料.该材料的研发极大地丰富了高分子物理学、高分子化学和材料学的研究内容,拓宽了聚合物材料在现代工业中的应用,同时把聚合物材料研究推向了交叉科学的前沿.均聚物/嵌段共聚物/均聚物体系作为经典的三元聚合物共混体系,对其进行深入地研究,不仅可以促进人们对高分子科学中重要问题的理解,而且可为新型嵌段共聚物增容剂的改良和设计提供理论依据.近年来,有关聚合物共混体系的实验、理论和计算机模拟工作很多,并且取得了较大的进展,但是相关综述较少.本文以均聚物/嵌段共聚物/均聚物体系为例,综述该领域的基本概念和发展历史,并着重介绍两嵌段共聚物增容剂对该三元共混体系相行为和界面性质的影响.此外,还介绍了这一领域的关键科学问题、发展前景和研究方向.Polymer composite systems,also termed as ＂polymeric alloys＂,can provide a highly cost-effective way of creating novel materials with either characteristics of all the constituents or new desirable properties.The study of these systems is significant in polymer physics,polymer chemistry,material science and modern industrial applications,which leads to the result that multicomponent polymeric materials become the cutting edge of interdisciplinary scientific research. Due to their relatively simple structural features,homopolymer /diblock copolymer/homopolymer ternary materials provide a model system for studying some long-standing fundamental issues in polymer science and have potential engineering and functional applications. In recent years,this model system has been the subjects of extensive theoretical,experimental and simulation studies,and many important progresses have been achieved. However,related reviews about this field are still scarce. In this review article,we comprehensively describe the basic concepts and the development history in the field of polymer composite systems and highlight the effects of diblock copolymer compatibilizers on phase behaviors and interfacial properties of the ternary blends. In particular,the critical issues,development prospects,and research directions in this field are introduced as well.
