采用直接共混法和母料共混法制备了高密度聚乙烯（HDPE）/苯乙烯-乙烯-丁二烯-苯乙烯嵌段共聚物（SEBS）/八异丁基笼形倍半硅氧烷（oib-POSS）复合材料。结果表明：oib-POSS可提高HDPE/SEBS的耐热性，其添加方式对HDPE/SEBS的耐热性影响不大；oib-POSS对HDPE的结晶温度与熔点影响较小，但结晶度随着oib-POSS用量的增加先上升后下降；采用母料共混法制备的HDPE/SEBS/oib-POSS复合材料的力学性能明显优于HDPE/SEBS以及采用直接共混法制备的HDPE/SEBS/oib-POSS复合材料。当w（oib-POSS）为4%时，HDPE/SEBS/oib-POSS复合材料的综合性能最佳，拉伸强度与悬臂梁缺口冲击强度较HDPE/SEBS分别提高了13.82%，65.38%。
