Facile approach to obtain individual-nanotube dispersion at high loading in carbon nanotubes/polyimide composites

摘要

A big challenge in making a composite lies in achieving individual-nanotube dispersion of carbon nanotubes (CNTs) in a polymer matrix, without aggregation and entanglement and excellent interfacial adhesion between the CNTs and the polymers matrix. In this communication, using polyethylene glycol-200, we successfully prepared CNT-reinforced polyimide composites that exhibit individual-nanotube dispertion in the matrix at high-loading CNT's. The content of CNTs in a composite can reach 43 wt%.
