Study on PVP/C-MMT Nanocomposite Material via Polymer Solution-Intercalation Method

The vinyl polymer/montmorillonite nanocomposite (PVP/C-MMT) was prepared successfully using the way of polymer intercalation from solution. Gel permeation chromatography (GPC) result of PVP showed that polydispersity of PVP was 3.24 with broadly molecule distribution. The results of scan electron microscope (SEM) and thermogravimetry analysis (TGA) showed that the surface of MMT have changed hydrophility into lipophilic and the crystal layer of MMT broken down easily after modified MMT. The result of X-ray diffraction (XRD) and transmission electron microscope (TEM) showed that intercalated nanocomposite was prepared. The pickled sheepskins was tanned with 6% PVP/C-MMT associated with 2% chromate. The application result showed that it is an effective way to decrease use chromate for using nanocomposite.
