Abstract

Hybrid nanomaterials consisting of BaTiO3 nanotubes (BTO NTs) and polyaniline (PANI), hereafter denoted as BTO NT/PANI, were successfully prepared by a one-step in situ oxidative polymerization process of aniline monomers in the presence of BaTiO3 nanotubes, with ammonium persulfate as oxidant and hydrochloric acid as dopant. The structure and morphology of the nanocomposites were characterized by field emission scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray powder diffraction, thermogravimetric analysis, and X-ray photoelectron spectroscopy. The conductivity property of the hybrid nanomaterials was also investigated. Compared with pure polyaniline, BTO NT/PANI hybrid nanomaterials exhibited enhanced reflection loss properties, which can even be further improved with appropriate electromagnetic impedance matching. More importantly, microwave-absorbing properties of the nanocomposites can be simply modulated simply by controlling the BaTiO3 NTs content of the absorber for the required frequency bands. Therefore, these composites may be used as lightweight andhighly effective microwave absorbers. POLYM. COMPOS., 2013 © 2013 Society of Plastics Engineers
