Carbon nanotubes (CNT) are produced from a rare variety of natural vein graphite (VG) distinctive to Sri Lanka using electric arc discharge. Electric arc-discharge produces both single walled and multi walled nanotubes. The products are characterized using high resolution electron microscopy and Raman spectroscopy for verification and validation.
