Preparation and Structural Characterization of CMC/MMT Nanocomposite
Using montmorillonite (MMT) and sodium carboxymethylcellulose (CMC) as raw materials, CMC/MMT nanocomposites were prepared by the solution intercalation technique. The microstructures of MMT before and afier being intercalated were characterized by X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM). The results of XRD showed that when the adding amount of CMC increased from naught to 70wt％, the structures of MMT have no change basically; when the adding amount of CMC increased to 80wt％,the decrease of MMT (001) was significant; when the adding amount of CMC reached to 90wt％,the diffraction peak of (001) disappeared,which indicated that the layers of MMT have been exfoliated along (001) and the CMC/MMT intercalated structure has been obtained. The observations by HRTEM showed that the shapes of MMT are layer aggregation or agglomerated particles. The MMT added with 90wt％ CMC has changed into intercalated structure with altemating MMT and CMC order mainly,and the intercalated structure was characterized at the atomic scale.
