通过原位插层聚合法制备了两种丙烯酸树脂/蒙脱土纳米复合材料,采用X射线衍射、透射电镜及核磁共振等方法对纳米复合材料的结构进行了表征.研究结果表明,所制备的两种纳米复合材料均为剥离型纳米复合材料,纳米复合材料的热性能较相应聚合物提高20℃左右.应用结果表明,两种纳米复合材料均具有鞣制性能,其应用性能较相应聚合物有所提高.
Two kinds of acrylic resin/montmorillonite nanocomposites were prepared via in-situ polymerization. The structure of nanocomposites were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and nuclear magnetic resonance spectrum (NMR). The results show that two kinds of nanocomposites formed are categorized as exfoliated nanocomposites, they exhibite more than 20℃ improvement in thermal properties, compared to the unmodified polymer counterpart. The application results show two kinds of nanocomposites have tanning properties and their properties are improved in contrast to pure acrylic resin.
