摘要：In order to better understand the morphology and properties of polymer nanocomposites it is necessary to conduct their characterization by Transmission Electron Microscopy（TEM）.This work shows a technique through which the nanocomposite powder is mixed with a resin,and after cured,thin sections can be obtained by ultramicrotomy.Another technique presented in this work deals with the observation of clay powder in solution.In this work High Resolution Electron Microscopy（HRTEM） was used to obtain images of the nanocomposites and clay.Images with a high level of details were showed.Through the use of such techniques,it was possible to observe two types of clay morphology in polymer matrix and its distribution.The dimensions and hexagonal layers of the natural clay used as nanofiller for the nanocomposite were also observed.The X-ray Diffraction（XRD） was used to investigate the kaolinite and nanocomposite.
