Abstract: Recent studies on nanocomposites of acrylonitrile-butadiene-styrene/carbon nanotubes (ABS/CNTs) have been reviewed. A detailed introduction was given on their preparation methods as well as their mechanical, electrical, radar absorbing, thermal degradation, and flame retardant properties. It was found that with addition of small amount of CNTs, the elastic modulus, tensile strength, and modulus of ABS were greatly improved; the electric resistivity was much lowered and reached the requirement of permanent antistatic standard. The composites possessed excellent radar absorbing ability and flame retarding performance. Comprehensive analysis on the influence of different types, addition amounts, and pre-treatments of CNTs on above-mentioned properties of ABS/CNTs nanocomposites was made and the corresponding mechanism was presented and discussed.

Key words: carbon nanotubes, acrylonitrile–butadiene–styrene, nanocomposite, mechanical property, electrical conductivity, fire retardant property
