batteries capable of over 300% deformation have been developed with novel strategies such as self-similar serpentine interconnects [6] and origami of thin sheets. [7] In comparison with batteries, supercapacitors (SCs) have advantages of fast charge/discharge rate and long operating life, representing a promising candidate for energy-storage devices used in unconventional electronics. Existing stretchable SCs that use films or meshes of carbon nanotube (CNT) or graphene as electrodes [8] typically reach a stretchability of up to 30% to 300%. With ultra-stretchable gel electrolyte used, some SCs with CNT electrodes reported a stretchability of up to 1000%. [9] However, the fabrication of such stretchable SCs usually relies on the transfer of active material layers onto target substrates, which is a complicated, troublesome, time-consuming, and expensive process. Therefore, there is an urgent need to explore new strategies and seamless integration of the latest advances in materials and manufacturing to make stretchable and high-performance SCs. Printing techniques offer a promising solution to the scalable manufacturing of stretchable SCs. Over the past decade, printed electronics have attracted increasing attention for the fabrication of novel electronics, such as thinfilm transistors (TFTs), sensors, and energy storage devices, [1-4] owing to the unique advantages of low-cost, high-throughput, and ability for mass production. In particular, inkjet printing has many advantages, such as low-cost, direct writing, additive patterning, and scalable production, when applied to the Stretchable supercapacitors (SCs) have attracted significant attention in developing power-independent stretchable electronic systems due to their intrinsic energy storage function and unique mechanical properties. Most current SCs are generally limited by their low stretchability, complicated fabrication process, and insufficient performance and robustness. This study presents a facile method to fabricate arbitrary-shaped stretchable electrodes via 4D printing of conductive composite from reduced graphene oxide, carbon nanotube, and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate. The electrode patterns of an arbitrary shape can be deposited onto prestretched substrates by aerosol-jet printing, then self-organized origami (ridge) patterns are generated after releasing the substrates from holding stretchers due to the mismatched strains. The stretchable electrodes demonstrate superior mechanical robustness and stretchability without sacrificing its outstanding electrochemical performance. The symmetric SC prototype possesses a gravimetric capacitance of ≈21.7 F g −1 at a current density of 0.5 A g −1 and a capacitance retention of ≈85.8% from 0.5 to 5 A g −1. A SC array with arbitraryshaped electrodes is also fabricated and connected in series to power lightemitting diode patterns for large-scale applications. The proposed method paves avenues for scalable manufacturing of future energy-storage devices with controlled extensibility an...

Los materiales refractarios son de gran importancia para la humanidad, debido a su capacidad de resistir altas temperaturas. Son empleados en la industria del cemento, cerámica, vidrio, metalúrgica, siderúrgica y petroquímica. La mayor preocupación a nivel industrial, es que los materiales refractarios son sometidos a varios mecanismos de desgaste durante el proceso de producción, tales como: ataque químico, mecánico, termomecánico y carga térmica. Si el material no cuenta con las propiedades adecuadas, su durabilidad se verá afectada, y por ende los costos de producción. En este sentido la combinación de los nanomateriales, se convierte en una importante alternativa para mejorar las propiedades de los materiales refractarios, proporcionándoles mejor densidad, baja porosidad, resistencia a la erosión, baja conductividad térmica, entre otras. El presente artículo realiza una revisión de varios trabajos de investigación, acerca de la evolución de los nanomateriales aplicados a los materiales refractarios, entre los que se mencionan el uso de grafeno, dióxido de titanio, óxido férrico, magnesia, zirconia, alúmina y sílice, para mejorar las propiedades físicas de los materiales refractarios. De manera general, los estudios demuestran que el uso de los nanomateriales, provee a los materiales refractarios mejores propiedades, en rangos de concentración específicos. Sin embargo, todos los estudios han sido realizados a nivel de laboratorio, por lo que sería promisorio su uso a nivel industrial.

“…Considering all these prospects, an in situ synthetic method has been innovated to load graphene oxide into the COF matrix. Graphene is a promising conductive carbon material, because of the good conductivity, synthetic diversity, and high specific surface area. − However, graphene nanosheets are prone to be restacked owing to powerful van der Waals interactions between close nanosheets during the electrode manufacturing or charge/discharge cycling, which can affect the availability of the specific surface area for the electrolyte ion. − Therefore, similar to diverse 2D materials, the electrochemical property of most graphene-based materials is lower than the theoretical specific double-layer capacitance. − However, in the COF@rGO hybrid film, the multiple π electrons in the covalent organic frameworks assist π–π interactions with reduced graphene oxide . Benefiting from the in situ synthesis of the COF along the surface of the two-dimensional reduced graphene oxide nanosheets, the COF maintains a relatively few-layer structure, which could reduce the diffusion pathway and therefore promote ion diffusion.…”

The porous structural backbone and redox-active of covalent organic frameworks can facilitate the evolution of energy storage equipment with high electrochemical performances. However, the application of covalent organic frameworks as supercapacitor electrode materials in advanced energy storage equipment has been hindered on account of the insufficient conductivity and consecutive impoverished electrochemical performances. Here we give an account of an efficacious method for improving the electrical conductivity of anthraquinonecontaining covalent organic frameworks (COFs) by incorporating reduced graphene oxide (rGO) sheets into the COF. Benefiting from the in situ synthesis of the COF along the surface of the twodimensional rGO nanosheets, the obtained COF@rGO hybrid films possess important intermolecular π−π interaction between rGO nanosheets and the COF. Meanwhile, the presence of the COF can avoid accumulation of rGO nanosheets, thereby achieving effective electrolyte ion transportation. Therefore, the optimal COF@rGO film possesses a good specific capacitance of 451.96 F g −1 , showing breakthrough within COF-based electrodes. In addition, the assembled planar COF@rGO microsupercapacitor (COF@ rGO-MSC) delivers a large stable electrochemical window (2.5 V), a good energy density (44.22 W h kg −1 ), and an excellent structural stability.
