Fabrication and Properties of Composites of Linear Polyacrylamide and Functionalized Carbon Nanotubes

Abstract:

Polyacrylamide (PAM) was chemically anchored to the surface of multi-walled carbon nanotubes (MWCNTs) by atom transfer radical polymerization (ATRP) of acrylamide (AM). It started from the functional groups such as –COOH on the sidewall of MWCNTs, which derived from the oxidation of carbon nanotubes. FT-IR and ¹H NMR results shown that the multi-walled carbon nanotubes grafted PAM (MWCNT-g-PAM) have been successfully carried out. The MWCNT-g-PAM showed different relative weight loss kinetics with PAM determined by thermal gravimetric analysis (TGA). The transmission electron microscopy (TEM) shown that the PAM grafted polymer was wrapped on the surface of carbon nanotubes.
