将甲基丙烯酸缩水甘油酯接枝丙烯腈-丁二烯-苯乙烯(ABS-g-GMA)、聚碳酸亚丙酯(PPC)及蒙脱土(MMT)——无机蒙脱土(IMMT)或有机蒙脱土(OMMT)熔融共混制备了PPC/ABS-g-GMA/IMMT和PPC/ABS-g-GMA/OMMT复合材料。采用傅里叶红外光谱(FTIR)对自制的ABS-g-GMA进行了表征,并通过X射线衍射分析(XRD)、透射电子显微镜(TEM)及动态机械分析(DMA)研究了PPC/ABS-g-GMA/MMT复合材料的形态结构及动态力学性能。结果表明:甲基丙烯酸缩水甘油酯(GMA)成功地接枝到了丙烯腈-丁二烯-苯乙烯(ABS)分子链上;IMMT主要以团聚体的形式聚集在ABS-g-GMA相,有少部分ABS-g-GMA插入到了IMMT的片层结构中,而OMMT主要以剥离态的形式存在于复合材料中;IMMT及OMMT的加入使复合材料的储能模量有了很大程度的提高。
Glycidyl methacrylate grafted acrylonitrile-butadiene-styrene (ABS-g-GMA), polypropylene carbonate (PPC) and montmorillonite (MMT) -sized montmorillonite (IMMT) PMA / ABS-g-GMA / IMMT and PPC / ABS-g-GMA / OMMT composites were prepared by melt blending OMMT and OMMT. The self-made ABS-g-GMA was characterized by Fourier transform infrared spectroscopy (FTIR) and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and dynamic mechanical analysis (DMA) Morphological Structure and Dynamic Mechanical Properties of g-GMA / MMT Composites. The results showed that glycidyl methacrylate (GMA) was successfully grafted onto the acrylonitrile-butadiene-styrene (ABS) molecular chain. IMMT mainly aggregated in the form of agglomerates in the ABS-g-GMA phase. A small part of ABS-g-GMA was inserted into the lamellar structure of IMMT, while OMMT mainly existed in the composite in the form of exfoliated state. The addition of IMMT and OMMT enhanced the storage modulus of the composites .
