Abstract

A facile approach to polymer nanocomposites with singleโ€wall carbon nanotubes and cationic polymers is reported. The composite material was synthesized by producing carboxylic acid groups at the nanotube termini followed by a reaction with poly(allylamine) in water. Fourier transform infrared spectral and thermogravimetric analyses corroborate that the poly(allylamine) chains were wrapped on the surface of the carbon nanotubes. The scanning electron microscopic (SEM) image shows that the nanotubes were dispersed with little aggregation, thus, strongly suggesting that the poly(allylamine) chains have covered the singleโ€wall carbon nanotubes, which was further evidenced by transmission electron microscopy. The composites are soluble in water, and this solubilization process opens up new opportunities in the solution chemistry on pristine nanotubes.

## Abstract We report a facile method to accomplish the crosslinking reaction of PVA with SWNTs, MWNTs, and Cโ€60 using MW irradiation. Nanocomposites of PVA crosslinked with SWNT, MWNT and Cโ€60 were prepared expeditiously by reacting the respective carbon nanotubes with 3 wt.โ€% PVA under MW irradia
