Polymer composites based on polyimides and single-walled carbon nanotubes are of interest in space and aerospace industries, due to inherent thermal stabilities as thermal/electrical conductivities of the components. Unfortunately, it is very difficult to disperse the carbon nanotubes (CNTs) into the polyimide matrix. This work attempts this by predispersion of the CNTs in the precursor reactive materials, and then polymerization is carried out with the CNTs in place. When this is done, some
