EFFECT OF ADDITIVES ON STRUCTURES AND PROPERTIES OF POLYPYRROLE/GRAPHITE OXIDE NANOCOMPOSITES

Polypyrrole/graphite oxide nanocomposites has been prepared by in-stiu polymerization method.The effects of sodium dodecylbenzenesulfonate or NaOH as additives as well as no additive on structures and properties of nanocomposites were studied by XRD,FT-IR,TEM,electrical conductivity and CV,respectively.The results show that exfoliated nanocomposites were attained on conditions of NaOH as additive or no additive,and intercalated nanocomposite with order layer structure was developed in the presence of DBSNa. The electrical conductivity of intercalated nanocomposite is better than those of exfoliated nanocomposites,which is possibly induced by the improvement of PPy backbone regularity in the intercalated nanocomposite.
