摘要The improvement of electronic structure and electrical behaviour of low-density materials have been of great concern. Multiwall carbon nanotube (MWCNT) has been identified as a low-density material, which needs attention to be used mostly as a strengthening phase in lightweight metal lattice composites (MLC). In this work, vaporization and drying process were used to produce TiO2 incorporated MWCNTs nanocomposites. The incorporation of TiO2 is to improve electronic system as well as electrical behaviour of MWCNTs in oxidized atmosphere, which is essential in most of MLC processing methods. We have used field-emission scanning electron microscopy Raman spectroscopy, X-ray diffraction and X-ray photoemission spectroscopy techniques for the study of structural and electronic properties; whereas current-voltage technique was used for the study of electrical behaviour of the nanocomposites. The observed change in electrical behaviour of the nanocomposites with improvement of electric/bonding structure indicates possibilities of the material properties be tailored for electronic/electrical devices as well as photo-catalytic activity applications.
