We report a facile method to accomplish the crosslinking reaction of PVA with SWNTs, MWNTs, and C-60 using MW irradiation. Nanocomposites of PVA crosslinked with SWNT, MWNT and C-60 were prepared expeditiously by reacting the respective carbon nanotubes with 3 wt.-% PVA under, MW irradiation, maintaining a temperature of 100 degrees C, representing a radical improvement over literature Methods to prepare such crosslinked PVA composites. This general preparative procedure is versatile and provides a simple route to manufacture useful SWNT, MWNT and C-60 nanocomposites.
