An Innovative Method to Reduce Percolation Threshold of Carbon Nanotubes Filled Nylon6/Polystyrene Blends

Abstract:

Selective localization of carbon nanotubes (CNTs) at the interface of immiscible polymer blend was achieved by the method that poly(styrene-co-maleic anhydride) (SMA) was first reacted with CNTs, and then blended with nylon6/polystyrene (PA6/PS). In the PA6/PS blends, CNTs was localized in PA6 phase and the percolation threshold was 2wt%. However, for the PA6/PS/(SMA- CNTs) composites, TEM results showed that most of CNTs were selectively localized in matrix, but some of tubes were induced by SMA to disperse at the interface. The localization of CNTs at the interface caused the percolation threshold of PA6/PS/(SMA- CNTs) was only 0.33 wt%, which is much lower than that of PA6/PS/ CNTs.
