| 摘 要： | 通过原位聚合方法制备了以非水溶性聚合物(聚甲基丙烯酸甲酯,PMMA)为基体,与MgFe双氢氧化物(LDH)具有良好相容性的层离型纳米复合材料.采用小角、广角X射线衍射(XRD)及透射电镜(TEM)对纳米复合材料的微观结构进行了分析,通过热重分析(TG)和玻璃化转变研究了纳米复合材料在空气和氮气氛围下的热降解过程.实验结果表明,MgFe-LDH的引入显著提高了聚合物基体的热降解温度和玻璃化转变温度,纳米复合材料的热稳定性显著提高.其中含量1.6 wt%的层离型纳米复合材料在失重50%时的热降解温度比纯样提高约69℃.并且整个纳米复合体系的相容性良好,含量8.0 wt%的样品,其可见光透过率仍可达90%以上. |

| Abstract: | The novel exfoliated polymer nanocomposites(PMMA/MgFe(DS)-LDH) were synthesized by in situ polymerization based on poly(methyl methacrylate)(PMMA) and dodecyl sulfate-intercalated MgFe-layered double hydroxide(MgFe(DS)-LDH).The nanostructures were characterized by X-ray diffraction(XRD) and transmission electron microscopy(TEM),the PMMA/LDH nanocomposites were partially interacted and partially exfoliated.The thermal degradation mechanism was discussed by thermogravimetric analysis(TG) and T_g.The participa... |
