| 摘 要： | 采用原位插层聚合法制备聚甲基丙烯酸/蒙脱土(PMAA/MMT)纳米复合材料,探讨了引发剂用量对复合材料结构的影响。通过X射线衍射、红外光谱、固体核磁共振表征了改性蒙脱土及复合材料的结构。研究结果表明,甲基丙烯酸钠与蒙脱土具有一定的相互作用,甲基丙烯酸或甲基丙烯酸钠在蒙脱土层间聚合形成的PMAA/MMT纳米复合材料属于插层型纳米复合材料,引发剂用量对蒙脱土的层间距影响较小。

| Abstract: | The methacrylic polymer/ Montmorillonite(PMAA/MMT) nanocomposite was prepared via monomer in situ polymerization and the effect of initiator dosage on nanocomposite structure was discussed.The structures of modified MMT and nanocomposite were characterized by X-ray Diffraction,Fourier Transform Infrared Spectroscopy(FT-IR) and solid Nuclear Magnetic Resonance(NMR).The results show that there are interactions between sodium methacrylic and MMT.Methacrylic acid or sodium methacrylic has been polymerized between MMT layers and the methacrylic polymer/MMT nanocomposite formed belongs to intercalated nanocomposite.The influence of initiator dosage on interlayer space is not large. |
