Printed actuators and uses thereof
Printed active origami combines printed electronics with nanomaterial coated polymer based actuators to create active printed structures. The fabrication processes include the step of applying carbon nanomaterial coatings to polymeric films. Products produced by the processes include actuating materials, such as solid state actuators that can be used as active element(s) in a printable active origami robot.
1. A process for preparing an electroconductive product, the process comprising:
(a) combining from about 0.1% to about 5.0% (w/vol) of an electroconductive material with a mixture comprising water and at least one C1-C6 alcohol;
(b) sonicating the combination of step (a) for an effective period of time, thereby producing an electroconductive ink coating; and
(c) applying the sonication product of step (b) on a polymeric substrate whereby the product of step (c) is an electroconductive product.
2. The process of claim 1 further comprising:
(d) arranging the electroconductive product to form an active origami device.
3. The process of claim 2 wherein:
the active origami device is a robot powered by electricity, heat, and/or light.
4. The process of claim 1 wherein:
the electroconductive material comprises oxidized carbon nanotubes.
