Abstract

We have prepared metal matrix composites of a pewter alloy filled with liquid-exfoliated Molybdenum Telluride (MoTe₂) nano-platelets. The combination of MoTe₂ and pewter was chosen due to their near-identical densities, thus reducing the scope for buoyancy-induced separation during melt mixing. The addition of nanofiller results in a doubling of the Young's modulus, Y, for a volume fraction, V_f, of <1% MoTe₂, corresponding to a reinforcement of dY/dV_f = 110 GPa. We find that this degree of reinforcement to be reasonably consistent with that predicted by a simplified version of Halpin-Tsai theory.
