✦ Synopsis

Industrial, CVD multi-walled carbon nanotubes are shown to form true solutions by reduction with alkali metals and subsequent exposure to polar solvents such as DMSO. Addition of an electrophile such as bromo-decanoic acid allows functionalization of the tubes. The whole process, dissolution and functionalization includes no harsh treatment such as acid treatment and/or sonication and allows to saturate the outer surface of the MWCNTs with functional groups. Comparison is made with previous work on single-walled carbon nanotubes.

A series of octadecylamine (ODA) grafted multi-walled carbon nanotubes (MWNT) were prepared and characterized by NMR, FTIR, DSC and XRD. It is revealed that the ODA chains grafted on MWNT are partially crystallized, though the packing structure is not as perfect as the pure ODA. It is believed that

## Abstract 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 irradia

## Abstract **Summary:** Multi‐walled carbon nanotubes (MWNTs) have been successfully modified with polyacrylonitrile (PAN) by a cathodic electrochemical process. The surface‐modified MWNTs afforded are then dispersible in good solvents for PAN, such as __N__,__N__‐dimethylformamide (DMF). Collecte
