J. Environ. Nanotechnol., Volume 6, No 3 (2017) pp. 34-44
Abstract
A novel modified AC method - VSA methodology (with KRS or NTFDS theory) was adopted in this present work for the preparation of SWCNTs from natural organics i.e., Tapioca leaves towards the possiblility of application to Opto-electronic devices : 3D - high efficiency Solar cells, Flat panel displays, LEDs & Lasers, Magnetic storage devices and Nano thermometers. Structural, Compositional, Surface Morphological and Nano structural Characterizations were carried out on harvested products. The effects of optimizations parameters like pH of the various dipping solutions (acidic, basic and neutral), volume of dipping solutions, various types and parts of the materials, various dipping timings, number of annealing and dipping, various annealing temperature, various time of annealing and various dipping solution temperatures on structural, compositional, surface morphological, nano-structural characterizations of materials and on high grade SWCNTs growth with high yield were studied intensively. Inferences from characterizations were derived and graphically emphasized. Correlation studies between these characterization inferences (such as grain size, purity) and above optimization parameters were carried out with a high light on yield of high grade SWCNTs. Beyond all of these, we have carried out a new feasibility study at first time, which comprises the possible usage of precursor organic carbon source i.e., Tapioca leaves for high grade SWCNTs with high yield via a low cost technique and methodology as value in commercial efforts.
