Conductive elastomers as an irreplaceable component of stretchable electronics, have recently gained significant attentions. Herein, we report highly conductive, sensitive, stretchable, and fully printed hybrid composites comprising carbon nanotubes (CNTs), silver nanoparticles (Ag NPs) and hydroxyl-poly (styrene-block-butadiene-block-styrene) (OH-SBS) polymer.The electrically conductive composites are fabricated via direct evaporation of CNTsdispersed OH-SBS suspension under mild heating condition, followed via an iterative process of silver precursor absorption and reduction, generating amounts of Ag NPs on both the surface and inner regions of the CNTs-embedded composites. The obtained CNTs-Ag NPs embedded composites possess superior electrical conductivity of 1228 S cm -1 , high break elongation of 540%, and high gauge factor of 26500. The unique hierarchical multiscale hybrid architecture of CNTs-Ag NPs and utilization of OH-SBS enable the as-prepared composites to exhibit huge piezoresistive behavior with a broad range of tensile strain.Moreover, handwriting electric circuits with diverse geometries are designed, and the printed strain gauge sensor could successfully detect sign language via its strain-sensing behavior. We 2 believe that our hierarchical multiscale hybrid design could pave a way for the simple fabrication of stretchable circuits for wearable electronics. decorated with self-assembled silver NPs (Ag NPs). Although the maximum conductivity of the hot-rolled film reached 5710 S cm -1 , more addition of silver flakes resulted in a brittle film with phase separation. Lee [15] reported Ag NWs-Ag NPs embedded highly stretchable conductive fibers using a wet spinning method and an iterative process for Ag precursor absorption and reduction. The as-prepared composite fiber demonstrated obvious strainsensing behavior with the GF of ≈15 at 100% strain. However, the aggregation and fracture of Ag NWs, and the weak adhesion between the poly (styrene-block-butadiene-block-styrene) (SBS) and Ag NWs hindered the charge transfer among conductive fillers, thus affecting the STA/ethanol solution for 60 min. In this procedure, STA and ethanol solvent are both rapidly absorbed into the composites due to the coordination interaction between Ag + and unsaturated or aromatic bonds, and the ion-dipole interaction between the trifluoroacetate anions (CF 3 COO -) and the hydroxyl group of ethanol. [24] Fig.1 c and e display a typically top view SEM image, cross-sectional SEM image and corresponding energy dispersive spectrometer (EDS) mapping images of OH-SBS/CNTs/STA composites, which reveal that the absorbed STA is not only distributed uniformly on the surface of the swollen composites, but also 9 would occupy certain space to hinder the absorption of Ag precursor, thereby lowering the Ag NPs concentration and electrical conductivity of the composite materials, which is confirmed from TGA results in Fig.S6b.

“…Currently, the development of metal nanowires such as silver (Ag) (2), gold (Au) (3), indium (In) (4) or copper (Cu) (5) are became the center of attention of material research and industrial applications. Copper nanowires can be an alternative to silver nanowires or indium tin oxide (ITO), because it has a low price to be used as a transparent electrode [6][7]. Copper nanowires can be synthesized in a mass scale (several grams) and printed on a transparent substrate, and showed better quality than carbon nanotubes [7].…”

Abstract.Copper nanowires (CuNWs) for different synthesis temperatures were prepared by solution-grown method. The surface morphology and electrical resistance of CuNWs were investigated. The surface morphology analysis describes the synthesis of long (> 20μm), thin (< 60 nm), and mono-dispersed CuNWs. Thus, in the case of temperature treatment from 4 °C to 80 °C in water based solution, the CuNWs has diameter of about 71 nm, length up to 37 μm and electrical resistance (R) at 0.1 Ω. This study suggests that the as-prepared copper nanowires (CuNWs) with diameter and electrical resistance tunability might be utilized as flexible transparent conducting electrode.

“…Traditionally, micro‐supercapacitors are fabricated on smooth substrates such as SiO 2 /Si, glass, and plastic, employing microfabrication techniques. However, office paper may not be compatible with the solvents and baking temperatures used during the typical microfabrication process . Due to the electrical conductivity and electrochemical properties of MXenes, it is possible to directly pattern MXene as micro‐supercapacitors as it can act as both the current collector and active material.…”

Additive‐free, single step formulations of MXene‐in‐water inks are developed from clay‐like titanium carbide (Ti3C2) sediments. Solution‐processable Ti3C2 inks are compatible with stamping, printing, painting, and writing on a variety of substrates. Specifically, MXene‐in‐water inks at higher concentrations of 30 mg mL−1 are employed in commercially available pens for dispensing and patterning 2D MXene directly. These MXene pens are employed either manually or automatically using an AxiDraw, enabling direct‐writing and complex patterning of functional MXene devices. Versatile MXene pens show compatible writing on a variety of substrates, including paper and polymers, where the deposited ink is used as a passive circuit, similar to silver and copper nanoparticle inks. Written MXene lines without additional post‐treatment exhibit length dependent resistance, showing typical resistivity values between carbon based and metal nanoparticle inks. Current collector‐free fabrication of MXene micro‐supercapacitors is demonstrated on unconventional platforms including paper, textiles, and curved surfaces directly.
