Polytetramethylene ether glycol (PTMEG) was used to functionalize multi-walled carbon nanotube (MWNT) by grafting to produce MWNT-g-PTMEG. These functionalized nanotubes were then dispersed in thermoplastic polyurethane (TPU) to form a TPU/MWNT nanocomposite. It was found that the functionalization resulted in improved dispersion of the nanotubes in the TPU material. The tensile strength and elongation at break of the nanocomposite were also enhanced by the addition of the nanotubes in ...
