Synthesis, Characterization And Multifunctional Applications Of Carbon Nano-tube Composites

A systematic study of carbon nanotubes functionalization, making compositeswith metal oxides and its application in laser produced plasma EUV source target,sonocatalytic degradation of methylene blue dye, Superhydrophobic surfaces andantidiabatic activity are presented. The functionalization of carbon nanotubes was based onchemical oxidation using different oxidizing agents by refluxing and Sonication. Thesynthesis of carbon nanotubes and tin oxide nanocomposites employed hydrothermalmethod using tin salt as a precursor. The energy bandgap of the SnO2/MWCNTnanocomposites were tuned (from3.68eV to2.93eV) using different oxidizing agentsfunctionalized carbon nanotubes and its hydrothermal reaction for SnO2Thenanocomposites showed excellent low density target materials for laser produced plasmaEUV source because of high absorption of Nd:YAG laser light and low debris generation.The nanocomposites first time used for the sonocatalytic degradation of methylene blueand highest rate constant (0.1086min-1) were achieved of any types of carbon nanotubesand metal oxides composites. By the addition of silicon oxide to SnO2/MWCNTnanocomposites using sol-gel method and it studied for the superhydrophobic surfaces ofliquid lens. The Superhydrophobic surfaces showed177.8ocontact angle, hysteresis lowerthan3oand adhesion power lower than300μN. Finally a facile functionalization ofmultiwall carbon nanotubes(MWCNTs) using95%concentrated nitric acid were made forantidiabetic activity and it showed41.2%Aldose Reductase inhibition in vitro activity;further docking study of it revealed that the carboxylic functional group on the surface ofMWCNTs played an important role in the activity.
