Abstract:
New stretchable electrically conductive composite materials comprising at least one polymer and a plurality of nanoparticles are provided, which exhibit high conductivity even at high strain levels. The composite may comprise polyurethane as the polymer and spherical gold nanoparticles. Such materials have conductivity levels as high as 11,000 Scm −1  at 0% strain and 2,400 Scm −1  at 110% strain. Furthermore, certain embodiments of the composite have a maximum tensile strain of 480% while still exhibiting conductivity of 35 Scm −1 . The inventive materials are highly flexible, highly conductive and suitable for a variety of applications, especially for advanced medical devices, implants, and flexible electronics. The disclosure also provides methods of making such stretchable electrically conductive nanocomposites, including formation by layer-by-layer and vacuum assisted flocculation. In certain embodiments, stretchable chiral plasmonic composite materials for use as optic devices and methods for making them are provided.

Claim (Index 5):
A method for forming a stretchable chiral plasmonic material comprising:\n applying a first charged material having a first polarity to a twisted substrate having a second polarity opposite to the first polarity; applying a second charged material having the second polarity over the first charged material in a layer-by-layer process, wherein the first charged material and the second charged material are distinct from one another and selected from a polymer and a plurality of nanoparticles; and removing the first charged material and the second charged material from the twisted substrate, wherein the first charged material and the second charged material together define a plasmonic film having either a left-handed chirality or a right-handed chirality based on a rotational direction of the twisted substrate.
