X射线衍射法研究天然橡胶/黏土纳米复合材料的插层过程
Study on Intercalating Stage of Natural Rubber/Clay Nanocomposites by X-ray Diffraction
摘要
Abstract
The organic clay(Org-clay) was prepared by alkyl ammonium ions treating of Na-montmo-rillonite, and then the natural rubber(NR)/Org-clay nanocomposites were prepared by intercalation method. The structure and morphology of the nanocomposites were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM), the results show that Org-clay can disperse in the rubber matrix at nanometer size. The result of XRD indicated that natural rubber chains could be intercalated into the interlayer of the Org-clay during the mixing stage. During the vulcanizing stage, with increasing vulcanization time the basal space of Org-clay was slightly increased. At the end of rubber vulcanization process, the NR chains were fixed in the interlayer of the Org-clay because of cross-linked network structure of vulcanizate.关键词
