Abstract

Multiwalled carbon nanotubes (MWNTs)-reinforced poly(hydroxyaminoether) (PHAE) was fabricated via one pot graft-from method. The modification of MWNTs and in situ polymerization of PHAE were combined in one reaction pot without interruption for the purification of modified carbon nanotubes. Fourier transform infrared, scanning electron microscopy, transmission electron microscopy, and Raman spectra clearly indicated that PHAE was successfully attached to the surface of MWNTs via esterification reaction between epoxy and carboxylic acid from MWNTs. Tensile tests showed that the tensile strength and modulus of PHAE/MWNTs composites were improved compared with that of pristine PHAE. Moreover, the reinforcing effect of one pot graft-from method was found to be better than that of graft-to method. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
