Abstract

In this work, conducting composites of nanocellulose (NC)/polypyrrole nanoparticles (NPPy) and silver nanoparticles (AgNPs), i.e., NC/NPPyAg, were synthesized for the first time, to the best of our knowledge, via in situ emulsion polymerization of pyrrole in the presence of surfactant dopants. The AgNPs acted as an oxidizing agent to simultaneously incorporate nanoparticles into the prepared composites. The structures and morphologies of the prepared composites were studied using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), UV-Vis Spectra, thermogravimetric analysis (TGA), and scanning and transmission electron microscopy (SEM and TEM) techniques. Additionally, the prepared composites were characterized by their conductivities, and the dielectric constants (ε΄), dielectric losses (ε˝), and AC conductivities were studied for the prepared composites with an increasing NPPy content as a function of the frequency.
