Abstract

Different morphologies (worm-like, straight and twisted) of multiwalled carbon nanotubes (MWCNT) are synthesized by carefully controlling the C2H2 flow rate. Unique mixed ferrite nanoparticles were synthesized and characterized as the appropriate catalyst for the growth of MWCNT. Scanning electron microscope and transmission electron microscope was extensively used to explore the morphological and structural properties. Electrical properties of MWCNT suggest semiconducting behavior. Infrared (IR) radiation detection is demonstrated using MWCNT and prototypes of room temperature and low temperature. IR radiation detectors have been made using different morphologies of MWCNT as the active sensor material.
