| 摘 要： | 在N,N-二甲基乙酰胺溶剂中，以对氨基苯甲酸（AB）修饰改性的ZnAl双氧氧化物（ZnAl LDH），通过原位插层方法制备聚酰亚胺／ZnAl双氢氧化物纳米复合材料。采用XRD、TEM、DMA、TGA等对其结构进行表征，与纯聚酰亚胺材料相比。纳米复合材料的储能模量、损耗模量和玻璃化转变温度L、热失重等性质，都有较大的提高。

| Abstract: | Layered double hydroxides(LDH) was modified by the amino benzoate in N,N-dimethylacetamide(DMAc).Polyimide/ ZnAl layered doubled hydroxide(PI/ ZnAl LDH) nanocomposites were synthesized by a solution intercalation method.Their structures and properties were characterized by X-ray diffraction(XRD),transmission electron microscopy(TEM),dynamic mechanical analysis(DMA) and thermogravimetric analysis(TGA).It is shown that these nanocomposites exhibited higher storage ,loss module and thermal properties compared to virgin polyimide. |
