Abstract：Carbon nanotubes(CNTs) were synthesized by CVD method,and then were dispersed in CuSO4 solution with the help of sonication.Dehydration and reduction in hydrogen atmosphere were carried out to obtain CNT/Cu composite powders.The composite powders were characterized by using SEM,TEM and XRD.The results showed that CNTs were uniformly dispersed in the composite powder,and some combined with Cu nanoparticles or were covered with Cu.
