Metal-polymer composite with nanostructured filler particles and amplified physical properties.

Bloor, D. and Graham, A. and Williams, E. J. and Laughlin, P.J. and Lussey, D. (2006) 'Metal-polymer composite with nanostructured filler particles and amplified physical properties.', Applied physics letters., 88 (10). p. 102103.


The limits of conductivity of a novel elastomeric matrix–nanostructured nickel powder composite are reported. The conductivity falls by a factor of 2×1014 for compression and by a similar amount in extension. Uncompressed and highly compressed composite displays ohmic behavior but between these limits the current-voltage characteristics are highly nonlinear. The matrix intimately coats the filler so that even above the expected percolation threshold the composite has a very low conductivity. The conductivity of the composite is increased under all mechanical deformations. These and other unusual properties are amplified versions of smaller effects seen in composites containing less highly structured fillers.
