Preparation of polypyrrole (PPy)-derived polymer/ZrO 2 nanocomposites

摘要: New polypyrrole (PPy)-derived polymer/ZrO2 nanocomposite materials are prepared by single-step oxidative polymerization of pyrrole (Py) and/or N-methylpyrrole (mPy) in the presence HCl-functionalized ZrO2 nanoparticles and ammonium persulfate. The physicochemical features PPy–ZrO2, poly(Py-co-mPy)–ZrO2 PmPy–ZrO2 hybrids were analyzed XPS, FTIR, XRD UV–Vis techniques. To explore advantages these nanocomposites for potential applications, their thermal, conductive electrochemical properties investigated. characterization reveals that a chemical bonding, based on electrostatic interactions, is established between polymers nanoparticles. Interestingly, it found growth polymer surface Cl-functionalized becomes more significant as Py moiety (–NH– species) content increases. thermal stability conductivity increase hybridization with This assigned to affective interaction Particularly, resulting keep high conductivities, ranging 0.323 0.929 S cm−1. Finally, voltammetric shows PPy–ZrO2 electroactive, thus demonstrating capability applications. These results highlight great influence nanoparticle interface nature monomer formation properties.
