| 中文摘要: |
| 采用单体插层聚合方法制备聚氨酯（PU）/有机蒙脱土（OMMT）纳米复合材料，并对其结构和性能进行分析。结果表明，经双羟乙基十二烷基三甲基氯化铵改性得到的OMMT(DK2)层间距较大；DK2质量分数为0.03时，PU/OMMT纳米复合材料中OMMT剥离程度较大，PU的插层效果较好，复合材料的物理性能和热稳定性能优良。 |
| 英文摘要: |
| The PU/organo-montmorillonite (OMMT) nano-composites were prepared by monomer intercalating polymerization，and their structures and properties were investigated.The results showed that the distance between layers of OMMT(DK2) modified by bis-hydroxyethyl dodecyl trimethyl ammonium chloride was larger；and when 3% DK2 by mass was used，the OMMT in PU/OMMT nano-composite was more completely exfoliated，the PU was more effectively intercalated into OMMT，and a nano-composite with excellent physical properties and thermal stability was obtained. |
