POLYAMIDE RESIN COMPOSITION CONTAINING MULTILAYER CARBON NANOTUBE

摘要

PROBLEM TO BE SOLVED: To provide a polyamide resin composition which has excellent strength at room temperature and at high temperature and contains a functionalized carbon nanotube and a polyamide resin.SOLUTION: The polyamide resin composition contains the polyamide resin and the multilayer carbon nanotube which has 0.8-1.6 of a ratio (Id/Ig) (Id is a peak area of a band between 1,565 cmand 1,600 cmof a Raman scattering spectrum; Ig is that of a band between 1,335 cmand 1,365 cmthereof) and 0.1-5.0% of a thermal weight loss at 600°C in a nitrogen atmosphere and is functionalized by treating the surface thereof with hydrogen peroxide.
