These researchers figured out that by using a gold nanomesh material, they can
create the perfect surface for electronics: one that is flexible, conductive, and transparent all at once.
Although there has been talk about bendable
smartphones and even
bendable batteries,
no one has been able to create a material for truly flexible
electronics that allows for rolling, folding and easy carrying. In fact,
no one has been able to create something that has all three ideal
features of such devices: flexibility, conductivity and transparency.
However, the Houston team took gold nanowires and created a mesh
material. This material was then embedded on a transparent polymer. Gold
is more ideal than previously tested metals, such as silver and copper,
as it doesn’t oxidize easily, giving it better overall long-term
conductivity. To test this material, the scientists stretched it up to
160 percent. The nanomesh material only lost a small portion of
conductivity when stretched to its limit, but that conductivity returned
when it snapped back to its original form.
