A simple strategy to achieve very low percolation threshold via the selective distribution of carbon nanotubes at the interface of polymer blends

Abstract

Selective distribution of carbon nanotubes (CNTs) at the interface of immiscible polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) is achieved via a combination of adding maleic anhydride grafted ABS (ABS-g-MA) and using an appropriate processing procedure. The composite shows a much lower percolation threshold of 0.05 wt%. The value obtained here is the smallest percolation threshold reported so far, comparing with those in the literature.
