Asymmetric Pentagonal Metal Meshes for Flexible Transparent Electrodes and Heaters

Polymer-metal hybrid transparent electrodes for flexible electronics

Despite nearly two decades of research, the absence of ideal flexible and transparent electrodes has been the largest obstacle in realizing flexible and printable electronics for future technologies. Here we report the fabrication of 'polymer-metal hybrid electrodes' with high-performance properties, including a bending radius <1 mm, a visible-range transmittance>95% and a sheet resistance <10 ...

Transparent and Stretchable Metal Electrodes

Thin layers of lamellar-forming polystyrene-block-poly (methyl-methacrylate) (PS-b-PMMA) provide the templates for fabricating nanowires with a “fingerprint” morphology. The electrical characteristics of the nanowires were measured, and largely deviated from simulated devices due to high defect density. Their highly curved conformation makes the nanowires strong candidates for electrical testin...

Cu Mesh for Flexible Transparent Conductive Electrodes

Copper electrodes with a micromesh/nanomesh structure were fabricated on a polyimide substrate using UV lithography and wet etching to produce flexible transparent conducting electrodes (TCEs). Well-defined mesh electrodes were realized through the use of high-quality Cu thin films. The films were fabricated using radio-frequency (RF) sputtering with a single-crystal Cu target--a simple but inn...

Flexible, transparent dielectric capacitors with nanostructured electrodes

Flexible, transparent electrodes using carbon nanotubes

We prepare thin single-walled carbon nanotube networks on a transparent and flexible substrate with different densities, using a very simple spray method. We measure the electric impedance at different frequencies Z(f) in the frequency range of 40 Hz to 20 GHz using two different methods: a two-probe method in the range up to 110 MHz and a coaxial (Corbino) method in the range of 10 MHz to 20 G...
