Abstract
Devices and methods relating to stretchable electronics. A stretchable electronic film includes an insulating polymer and less than 1 wt % of a semiconducting polymer. Manufacturing a multi-layered, stretchable electronic device characterized by a single peel-off step for integrating the components of the device rather than a multi-peel synthesis of the device.
Claims20
A film comprising:
- an insulating polymer;
- and
- a semiconducting polymer;
- wherein:
- the semiconducting polymer is present in an amount of 0.1 wt % to 3 wt %;
- and
- the film is phase-separated and comprises a first layer primarily comprising the insulating polymer and a second layer primarily comprising the semiconducting polymer.

A film comprising:
- an insulating polymer;
- and
- a semiconducting polymer;
- wherein:
- the semiconducting polymer is present in an amount of 0.1 wt % to 3 wt %;
