“…Nano-fillers are being used in many cases to improve mechanical properties such as toughness, modulus and strength with unexpected improvements in many cases [3][4][5]. One particular area of active research relates to the development of conductive composites made with nano-fillers [6][7][8][9][10].…”

a b s t r a c tWhen nickel nanostrands (NiNs) are embedded inside of highly flexible silicone, the silicone becomes an extremely piezoresistive sensor capable of measuring a large dynamic range of strains. These sensors experience an increase in conductance of several orders of magnitude when strained to 40% elongation. It has been hypothesized that this effect stems from a net change in average junction distance between the conductive particles when the overall material is strained. The quantum tunneling resistance across these gaps is highly sensitive to junction distance, resulting in the immense piezoresistive effect. In this paper, the average junction distance is monitored using dielectric spectroscopy while the material is strained. By incorporating new barrier height measurements of the base silicone material from a nanoindentation experiment, this experiment validates previous assumptions that, on average, the junctions between NiNs decrease while the sample is strained, instigating the large piezoresistive effect. The nature of the material's response to strain is explored and discussed.

The effects of pseudoelastic metal nanowires on the mechanical performance, thermal stability, and electrical conductivity of an elastomeric matrix were investigated. Subnanometer pseudoelastic metal nanowires were synthesized, and methodologies were developed for their functionalization and uniform dispersion in elastomer matrices. Pseudoelastic nanowires were found to significantly increase the stiffness, strength, electrical conductivity, and thermomechanical stability of the elastomer matrix while retaining its nonlinear strain recovery capability. These qualities are realized using low nanowire dosages (∼1 wt %). The combinations of qualities offered by this new class of nanocomposites are of significant value to major commercial markets.
