Synthesis and characterization of conducting polypyrrole-polymannuronate nanocomposites

Abstract

Polypyrrole-polymannuronate (PPy-PM) composite films were studied by preparing the composites via in situ deposition techniques. These studies on the chemical interactions, structural morphology, and thermal properties of the films support the formation of PPy-PM composites, and suggest that the ratio of pyrrole to PM is tailored to optimize the potential crosslinking inside the composite. The room temperature current-voltage characteristics and the frequency-dependent AC conductivity of the PPy-PM composites were studied within the frequency range of 102 to 106 Hz. Based on the aforementioned properties, the synthesis of PPy-PM composite films may suggest the future development of biomimetic materials that can be used to create new multicomponent and multifunctional bionanocomposite materials. © 2009 Springer Science+Business Media B.V.
