Microwave-polyol Process for Functionalizing Carbon Nanotubes with SnO2and CeO2Coating

Dispersing and functionalizing multiwalled carbon nanotubes in TiO2 sol.

We report that oxidized multiwalled carbon nanotubes (MWCNTs) can be synchronously dispersed and functionalized in TiO2 sol via an in situ sol-gel process. Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and atomic force microscopy (AFM) were used to characterize the functionalized MWCNTs. The results revealed that the hydrolysis and condensat...

Synergistic photothermal ablative effects of functionalizing carbon nanotubes with a POSS-PCU nanocomposite polymer

BACKGROUND The application of nanotechnology in biology and medicine represents a significant paradigm shift in the approach to the treatment of cancer. Evidence suggests that when exposed to near-infrared radiation (NIR), carbon nanotubes (CNTs) dissipate a substantial amount of heat energy. We have developed a novel nanocomposite polymer, polyhedral oligomeric silsesquioxane poly (carbonate-u...

Microwave Absorption Characteristics of Carbon Nanotubes

Microwave-Assisted Preparation of Carbon Nanotubes with Versatile Functionality

Since the accidental discovery of carbon nanotubes (CNTs) during the synthesis of fullerene by Iijima (Iijima 1991), tremendous research has been done on CNTs. CNTs are under intense investigation owing to their spectacular mechanical and electrical properties (Vazquez, Georgakilas, and Prato 2002). Many ways are currently available for the production of CNTs, which include arc-discharge (Journ...

Microwave-Assisted Modification of Carbon Nanotubes with Biocompatible Polylactic Acid

Polylactic acid (PLA) was successfully covalently grafted onto multi-walled carbon nanotubes (MWCNT) by microwave-assisted polymerization of lactide monomers. The final products MWCNT-g-PLA were characterized with Fourier-transform IR (FTIR), Raman spectroscopy, thermogravimetric analyses (TGA) and transmission electron microscopy (TEM). The results indicated PLA chain was covalently attached t...
