Abstract

We report the success in synthesis of BaTiO3 (BTO) coating on acid-treated functionalized multiwall carbon nanotubes (MWCNTs). Functionalization treatment, coating temperature, and coating time were optimized in order to obtain the dense coating of BTO. Contact angle measurements were conducted on MWCNT surface to quantify the effectiveness of functionalization and were correlated with percentage coating. Coating thickness in the range of 5-15 nm was confirmed by using high-resolution transmission electron microscopy. X-ray photoelectron spectroscopy was used to confirm the formation of BTO perovskite phase. Microstructural characterization and elemental analysis were performed using scanning electron microscopy and energy-dispersive spectroscopy to confirm the homogeneous coating with high yield. Possible application of these fully coated MWCNTs can be in flexible pressure sensors.
