摘　　要：为提升聚己二酸-对苯二甲酸丁二醇酯(PBAT)较差的氧气和水蒸气阻隔性能,利用十六烷基三甲基溴化铵(CTAB)对云母(Mica)进行改性,得到改性Mica(CMica),将PBAT、聚碳酸亚丙酯(PPC)与Mica和CMica热压成型制备PBAT/PPC/Mica及PBAT/PPC/CMica复合材料。对PBAT/PPC/Mica及PBAT/PPC/CMica的微观形貌、热稳定性、力学性能、氧气及水蒸气阻隔性能进行研究。结果表明:与Mica相比,CMica在PBAT/PPC中分散状态得到改善。PBAT/PPC/CMica的力学性能、氧气及水蒸气阻隔性能均比PBAT/PPC/Mica高。添加15%Mica时,PBAT/PPC/Mica的断裂伸长率为(91±60)%。而添加15%CMica的PBAT/PPC/CMica的断裂伸长率仍有(735±53)%。In order to improve the poor oxygen and water vapor barrier properties of poly(butylene adipate-coterephthalate)(PBAT),cetyltrimethylammonium bromide(CTAB)was used to modify mica(Mica)to obtain modified Mica(CMica).PBAT/PPC/Mica and PBAT/PPC/CMica composites were prepared by hot pressing of PBAT,poly(propylene carbonate)(PPC)with Mica and CMica.The microstructure,thermal stability,mechanical properties,oxygen and water vapor barrier properties of PBAT/PPC/Mica and PBAT/PPC/CMica were studied.The results show that the dispersion state of CMica in PBAT/PPC is improved compared with Mica.The mechanical properties,oxygen and water vapor barrier properties of PBAT/PPC/CMica are higher than those of PBAT/PPC/Mica.When 15%Mica is added,the elongation at break of PBAT/PPC/Mica is(91±60)%.The elongation at break of PBAT/PPC/CMica with 15%CMica is still(735±53)%.
