“…The formation of closely packed Au nanoparticle (NP) arrays has a profound effect on the physical and electrical properties of Au NP‐based films. For example, recent studies have reported that alkane thiol treatment of tetraoctylammonium bromide (TB)‐stabilized Au NPs on inorganic nanotubes weakens the interfacial interaction between the Au NPs and inorganic surfaces, thereby increasing the mobility of Au NPs, which grow through Ostwald ripening . It was also reported that neighboring Ag NPs with an interparticle separation of less than 5 Å can be fused, forming strong metallic bonds .…”

For the development of wearable electronics, the replacement of rigid, metallic components with fully elastomeric materials is crucial. However, current elastomeric electrodes suffer from low electrical conductivity and poor electrical stability. Herein, a metal‐like conductive elastomer with exceptional electrical performance and stability is presented, which is used to fabricate fully elastomeric electronics. The key feature of this material is its wrinkled structure, which is induced by in situ cooperation of solvent swelling and densely packed nanoparticle assembly. Specifically, layer‐by‐layer assembly of metal nanoparticles and small‐molecule linkers on elastomers generates the hierarchical wrinkled elastomer. The elastomer demonstrates remarkable electrical conductivity (170 000 and 11 000 S cm−1 at 0% and 100% strain, respectively), outperforming previously reported elastomeric electrodes based on nanomaterials. Furthermore, a fully elastomeric triboelectric nanogenerator based on wrinkled elastomeric electrode exhibits excellent electric power generation performance due to the compressible, large contact area of the wrinkled surface during periodic contact and separation.

The formation of nanotubes from inorganic materials with layered structures is described, and nonlayered materials from elements, oxides, nitrides etc., can also be synthesized. Complex misfit layered compounds, which have an inherent driving force to roll into tubular structures, have also been realized in nanotubular form. Progress in the synthesis of nanotubes from various inorganic compounds starting from elements, metal chalcogenides, pnictides, carbides, oxides and complex misfit layered compounds is discussed. We have deliberated on the mechanical, electronic, magnetic, optical, electromechanical, optoelectronic, tribological and thermal properties. Functionalization and the various applications of inorganic nanotubes are discussed.
