Infrared barriering behavior of reduced graphene oxide aerogel/ antimony tin oxide-polyaniline hybrids

Abstract Our previous work reported for the first time that antimony tin oxide (ATO) nanoparticles were prepared by using reduced graphene oxide aerogels (rGOA) three-dimensional network as scaffolds. In this study, we encapsulated the hybrid aerogels as a whole by conducting polyaniline (PANI) to investigate the effect of the introducing of PANI on microstructure and performance of rGOA/ATO-PANI hybrids. Characterization of the as-prepared samples were performed by scanning electron microscopy (SEM), fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), X-ray diffraction (XRD), Raman spectroscopy, ultraviolet visible near infrared spectroscopy (UV–VIS–NIR) and compressive stress. The electrochemical performances of hybrids were also investigated as well. The results showed that PANI was successfully grafted on rGOA/ATO and formed a compact film, which could further improve the conductivity of the hybrids and infrared absorption performance. The PANI had crystalline phases, and corresponding diffraction peaks were found in rGOA/ATO-PANI, which further indicated that PANI grafted on the surface of rGOA/ATO. The mechanical, electrochemical, infrared barriering performance of rGOA/ATO-PANI were improved as well.
