Hollow Glass Microspheres (HGM) is now challenging reinforcement for making low density composites with high stiffness, good electrical and mechanical properties. Carbon nano tubes when reinforced homogenously in the matrix it enhance properties of the composites to a commendable range. These CNTs are grown over HGM using chemical vapor deposition (CVD) technique at 600 °C temperature. Initially HGM were nickel coated by electroless deposition technique using nickel sulphate as the source of metal in the alkaline bath and then the catalyst coated HGMs were exposed to the mixture of acetylene and nitrogen gas at various temperatures to form CNT over HGM. Scanning Electron Microscopy (SEM) images explore the quality and dimensions of CNT. Other characterizations such as XRD, Raman Spectroscopy confirm the presence of CNT. Using these coated HGM as fillers in Epoxy, composites were fabricated and the same was characterized for compression using UTM and DMA using DMA analyzer. © 2019 Elsevier Ltd. All rights reserved.
