A New Approach to Synthesis of Free-Standing ZnO/MWCNT Nanocomposites by Vacuum Infiltration

Abstract

In this study, free-standing zincoxide/multiwalled carbon nanotube nanocomposite was synthesized by a multistep technique. Buckypapers having controlled porosity were prepared by vacuum ltration from oxidized multiwalled carbon nanotubes. Zinc acetate dihydrate (ZnAc) (Zn(CH3COO)2·2H2O) was used as zinc source and ethanol used as solvent. An appropriate amount of monoethanolamine was added to sol to change acid-base media. The solution was vacuum ltered through buckypaper and annealed at 350• C in air. It was found that the zinc oxide grows around the multiwalled carbon nanotubes to form a uniform composite. Morphology of zine oxide/multiwalled carbon nanotube was also studied in detail. Nanocomposite was characterized by X-ray diraction, scanning electron microscopy, and Raman spectroscopy.

A facile synthesis of zinc oxide/multiwalled carbon nanotube nanocomposite lithium ion battery anodes by sol–gel method

“…In literature, very few studies of free-standing ZnO films were applied for using different purposes such as anode application [4,34,35]. Akbulut et al synthesized ZnO/MWCNT nanocomposites by coating active materials on the filtration produced MWCNT buckypapers.…”

Synthesis, Characterization and Photocatalytic Efficiency of ZnO/MWCNT Nanocomposites Prepared Under Different Solvent Conditions

“…23 Up to know, various methods, such as chemical vapour deposition (CVD), plasma assisted sputter and vacuum infiltration, have been carried out to modify the surface of MWCNT with ZnO nanoparticles. [24][25][26] Koh et al also reported the coating of ZnO nanorods on MWCNT using hydrothermal synthesis. 27 CNTs decorated with ZnO nanoparticles were synthesized by Chen et al through oxidization, amination and modification of MWCNT with H 2 SO 4 , NH 3 and HNO 3 .…”
