Trapping carbon nanotubes at the interface of a polymer blend through adding graphene oxide: a facile strategy to reduce electrical resistivity

Abstract

Graphene oxide (GO) and carbon nanotubes (CNTs) were simultaneously introduced into an immiscible polymer blend. The dispersion of fillers and the electrical resistivity of the composites were studied. The results first showed that more CNTs were trapped at the blend interface by GO. Consequently, a remarkable decrease of electrical resistivity by about 7 orders of magnitude was achieved even if the concentration of CNTs was only 0.1 wt%. Further results showed that the quaternary composites exhibited much smaller percolation threshold (0.06 wt%) compared with the ternary composites containing only CNTs (0.24 wt%).
