Preparation and Characterization of Polypyrrole/Na+-Montmorillonite Nanocomposites by In-situ Polymerization
Polypro/Na+-montmorillonite nanocomposites were prepared by the in-situ polymerization of polypyrrole in the presence of MMT. The properties and structure polypyrrole/MMT nanocomposites were investigated by FTIR spectroscopy, X-ray diffraction. The FTIR spectroscopy showed that there was interaction between PPy and MMT clay. From XRD result shown the interlamellar spcing of the MMT became larger, which implied PPy had inserted into the MMT. With the increasing of PPy loading, the dc conductivity of composites was increased. When the PPy loading was higher than 20%, the dc conductivity of the composites reached up to 10~0S/cm.
