- Nanomaterial-Enabled Stretchable Conductors: Strategies, Materials and Devices
Shanshan Yao and Yong Zhu
Article first published online: 26 JAN 2015 | DOI: 10.1002/adma.201404446
Recent progress with regard to nanomaterial-enabled stretchable conductors and related stretchable devices is reviewed (e.g., capacitive sensors, supercapacitors and electroactive polymer actuators). Focusing on carbon nanomaterials (e.g., carbon nanotubes and graphene) and metal nanomaterials (e.g., metal nanowires and nanoparticles), this review provides fundamental insights into the strategies for developing nanomaterial-enabled highly conductive and stretchable conductors.

X-ray diffraction and X-ray tomography are performed on intermetallic particles undergoing lithiation in a porous electrode. Differences between ensemble phase evolution and that at a single-particle level are explored. It is found that all particles evidence core–shell lithiation; however, particles with internal porosity are more mechanically robust and exhibit less fracture.

A stable organic diradicaloid with an intermolecular quintet at room temperature as a polycrystalline solid is studied. The conclusion is supported by the observation of the ΔMs = ±2 forbidden transition, electron spin resonance (ESR) simulations, and density functional theory (DFT) calculations. In addition, the molecule, as the active component of a device, is an outstanding near-infrared photodetector with detectivity over 1011 cm Hz1/2 W–1 at 1200 nm.
- Self-Crack-Filled Graphene Films by Metallic Nanoparticles for High-Performance Graphene Heterojunction Solar Cells

Graphene, with cracks filled with gold nanoparticles, is grown by chemical vapor deposition on a Cu substrate. The crack-filled graphene not only exhibits superior electrical properties but also forms a better junction with other semiconductors. A high-quality crack-filled graphene/Si Schottky junction solar cell is achieved, demonstrating the highest fill factor (0.79) and best efficiency (12.3%).

Article first published online: 23 JAN 2015 | DOI: 10.1002/adma.201405249
Chiral conducting polymer films are self-assembled on ferromagnetic materials and exhibit an efficient spin filtering at room temperature. In addition, the present system displays asymmetric magnetoresistance with respect to zero magnetic field.
