摘要:
Methods for controlling and improving the conductivity of thermoplastic polymer composites containing CNTs or even for making these materials conductive when they are initially insulating. For example, methods including either injection moulding or extrusion at a temperature above the melting temperature of the polymer, or a subsequent heat treatment step of said composite obtained by injection moulding or extrusion.
