摘　　要：采用乳液聚合方法制备了聚甲基丙烯酸甲酯/有机蒙脱土复合微球。通过傅里叶红外光谱(FTIR)、X射线衍射(XRD)、扫描电镜(SEM)、热失重(TG)研究了交联剂乙二醇二甲基丙烯酸酯(EGDMA)对于微球的结构及性能的影响。结果表明:交联剂的加入,提高了蒙脱土与PMMA相互作用,交联剂含量的增大进一步提高了纳米复合微球的热学性能。The polymethyl methacrylate/organic montmorillonite composite microspheres were prepared by emulsion polymerization. The effects of crosslinking agent EGDMA on the structure and properties of microspheres were studied by Fourier infrared spectroscopy(FTIR), X-ray diffraction(XRD), scanning electron microscopy(SEM) and thermogravimetry(TG).The results showed that the interaction between montmorillonite and PMMA was improved by adding crosslinking agent, and the increase of crosslinking agent content improved the thermal performance of nanocomposite microspheres.
