Highly Conductive and Flexible Paper of 1D Silver-Nanowire-Doped Graphene

Abstract

A novel architecture of graphene paper is proposed to consist of "1D metallic nanowires/defect-free graphene sheets". Highly conductive and flexible papers of 1D silver nanowires (Ag NWs) and chemical vapor deposition (CVD) graphene sheets as an example were fabricated by a simple filtration method. CVD graphene paper possesses much higher electrical conductivity of 1097 S/cm, compared with other reported carbon-related papers (graphene, carbon nanotube, etc.). With the addition of Ag NWs to form Ag NWs/graphene paper, the electrical conductivity is further improved up to 3189 S/cm, even higher than ∼2000 S/cm of bulk graphite. Ag NWs/graphene papers have very good flexibility with the only <5% loss of electrical conductivity over 500 times mechanical bending. Highly conductive composite papers have potential in high-performance, flexible energy conversion and storage devices.

Highly Conductive Ordered Mesoporous Carbon Based Electrodes Decorated by 3D Graphene and 1D Silver Nanowire for Flexible Supercapacitor

“…(220), and (311) planes of metal Ag, respectively, suggesting the formation of Ag NWs. [ 23 ] The 3D graphene shows two diffraction peaks at 2 θ = 26.5° and 54.6°, which are attributed to the (002) and (004) planes of graphitic carbon(JCPDS 75-1621), respectively. The sharp peak at 26.5° indicates a high crystallinity and an interlayer space of 0.34 nm of the defect free CVD grown graphene, which is similar to the natural graphite but distinct from the commonly used defective reduced graphene oxide.…”

“…Finally, the surface of the carbon networks was decorated with Ag NWs, which were prepared according to previous literature. [ 23 ] The morphology of the 3D-graphene foam is investigated by scanning electron microscopy (SEM), as shown in Figure 2 a. Obviously, after removal of the Ni template, the graphene replicates the 3D network and porous structure of the Ni foam, and macropores with the size varied from 100 to 500 μ m are also maintained, without collapsing and cracking.…”

“…The average layer number of garphene is 8, with the electrical conductivity of 1097 S cm −1 . [ 23 ] After coating with OMC thin fi lm, the FE-SEM image shows that the surface of the GF-OMC is smooth and no cracking is observed in any domain ( Figure S2, Supporting Information). Many large mesopores packed with nanoparticles make the carbonaceous surface much coarser, suggesting open and accessible mesopore channels, which should provide open pathways for ion transportation.…”

Dispersant-free conducting pastes for flexible and printed nanocarbon electrodes

“…To further improve the electrical properties of the supra-LMWNT film, commercially available Ag NWs were used as highly conductive one-dimensional (1D) networking agents. Previously, 1D Ag NWs have been used to electrically modify two-dimensional (2D) graphene films 23,24 . In our study, the electrical conductivity of the supra-LMWNT film (Fig.…”

Copercolating Networks: An Approach for Realizing High-Performance Transparent Conductors using Multicomponent Nanostructured Networks

“…Recently, a number of applications of hybrid AgNW-graphene have been demonstrated in the literature ranging from its use as electrodes in light-emitting diodes to atomically thin barrier layer for protection against high-energy radiation [21,29,30,[52][53][54][55][56][57][58][59][60][61]. The schematic shown in Figure 6 summarizes the recent progress in the field and Table 2 presents their key physical properties.…”
