SEBS/PP/OMMT纳米复合材料的制备及性能庞绍龙1,2,王霞1,杨帆2(1.上海应用技术学院材料工程系,上海200235;2.华东师范大学化学系,上海200062)通过对蒙脱土的有机化处理,利用熔融插层的方法制备了苯乙烯-乙烯/丁烯-苯乙烯三嵌段聚合物(SEBS)/聚丙烯(PP)/有机蒙脱土(OMMT)纳米复合材料,对其结构、热性能及力学性能进行了研究。结果表明,少量有机化蒙脱土能够大幅度提高SEBS中聚苯乙烯嵌段的玻璃化转变温度,而对材料的力学性能影响很小。
Preparation and Properties of SEBS / PP / OMMT Nanocomposites PANG Shao-long1,2, WANG Xia1, YANG Fan2 (1.Department of Materials Engineering, Shanghai Institute of Technology, Shanghai 200235, China; 2.Department of Chemistry, East China Normal University, Shanghai 200062) Montmorillonite was prepared by the method of melt intercalation, and the styrene / ethylene / butylene-styrene triblock polymer (SEBS) / polypropylene / organic montmorillonite (OMMT) nanocomposite Materials, its structure, thermal properties and mechanical properties were studied. The results show that a small amount of organically modified montmorillonite can greatly improve the glass transition temperature of the polystyrene block in SEBS, but little effect on the mechanical properties of the material.
