POLYURETHANE/CARBON NANOTUBE COMPOSITES PREPARED BY SOLUTION
 MIXING AND THEIR PROPERTIES

Abstract

Abstract:

Carbon nanotubes were treated with acid， and their structures and dispersion stability

were further investigated. Polyurethane/carbon nanotube composites were prepared by solution mixing

and their structures were characterized by FTIR. The mechanical properties， elastic recovery

behavior and thermal stabilization of the composites were analyzed. It indicated that the carboxylic

acid groups were added onto the carbon nanotubes and the dispersion stability of CNTs in DMAc was

improved. The CNTs were hydrogen bonded onto the polyurethane matrix. Consequently， the mechanical

and thermal properties of the composites were both enhanced， while the elastic recovery behavior

was little affected.

Key words: polyurethane, carbon nanotubes, composites, solution mixing
