The CNT was synthesized using bio-hydrocarbon precursor, palm oil at 750°C synthesis temperature. The substrates were positioned at six different places where the distance between the subsequent substrate was fixed at 1 cm. Field emission scanning electron microscope, Raman spectroscopy and thermogravimetric analysis were employed for CNT morphology, quality and purity characterization. Samples deposited on substrate positioned at 3.0 cm showed good morphology of dense CNT distribution with higher quality and purity.</p> ER -
