“…[ 3,4 ] Liquid exfoliation of 2D materials offers an alternative way to produce 2D materials, [ 5,6 ] which can be formulated into inks for scalable deposition by additive manufacturing (AM)/3D printing (3DP) technologies. [ 7 ] Using an AM deposition, graphene and graphene oxide layers have been successfully printed to form macroscopic 3D structures, [ 8,9 ] as well as complex micron‐sized geometries [ 10 ] and 3D nanocomposites [ 11 ] on various substrates, including flexible substrates. [ 12,13 ] Of particular interest is the application of AM for graphene fabrication of functional heterostructures and electronic devices.…”

2D materials have unique structural and electronic properties with potential for transformative device applications. However, such devices are usually bespoke structures made by sequential deposition of exfoliated 2D layers. There is a need for scalable manufacturing techniques capable of producing high‐quality large‐area devices comprising multiple 2D materials. Additive manufacturing with inks containing 2D material flakes is a promising solution. Inkjet‐printed devices incorporating 2D materials have been demonstrated, however there is a need for greater understanding of quantum transport phenomena as well as their structural properties. Experimental and theoretical studies of inkjet‐printed graphene structures are presented. Detailed electrical and structural characterization is reported and explained by comparison with transport modeling that include inter‐flake quantum tunneling transport and percolation dynamics. The results reveal that the electrical properties are strongly influenced by the flakes packing fraction and by complex meandering electron trajectories, which traverse several printed layers. Controlling these trajectories is essential for printing high‐quality devices that exploit the properties of 2D materials. Inkjet‐printed graphene is used to make a field effect transistor and Ohmic contacts on an InSe phototransistor. This is the first time that inkjet‐printed graphene has successfully replaced single layer graphene as a contact material for 2D metal chalcogenides.

“…Once the material is dispersed in a liquid, the printing onto the substrate is the final step. For graphene enabled inks the main methods of printing that are scalable are ink-jet printing, aerosol-jet printing and screen-printing [20,21]. The choice of printing technique mainly depends on the thickness of material required.…”

Printable stretchable devices, which can be used in a wide range of environments, are required for a range of flexible or stretchable electronics applications. Here we present an ink containing liquid exfoliated graphene and natural rubber, which can be printed onto a variety of elastomeric substrates and recover conductance after multiple strains of up to 15%. In addition, the printed composite acts as a strain sensor with a gauge factor of around 7. The robust character of these composites allows for operation at temperatures up to 150ºC. The combination of the effectiveness of the device, along with comparable performance at elevated temperatures while being relatively cheap makes this ideal for integration with automotive components. For applications that require superior conductivity, silver nanowires can be added. The enhanced conductivity composite cannot withstand higher temperatures due to the breakdown of the nanowires. However, at room temperature the material shows similar recovery of conductivity after cycling leading to a highly conductive, room temperature, printable, stretchable composite.

“…Recently, tremendous attempts have been made to fabricate electronics by inkjet printing, most of which are based on the graphene inks . The first work is reported by Ferrari and co‐workers, in which graphene inks with a concentration of 0.11 mg mL −1 were prepared and thin‐film transistors were printed .…”

Ubiquitous portable electronics and the ever‐growing internet‐of‐things have necessitated the emergence of high‐end miniaturized devices as well as associated sophisticated printing technologies. With excellent solution processability and tunable electronic properties, 2 D materials stand as a promising candidate for functional inks that are readily printable for energy‐storage devices. In this Review, we outline the significance, status, and challenges that we are facing of the developments of 2 D materials‐based functional inks. Then, general ink formulation and basic knowledge of printing techniques together with their rheological requirements and enabled applications in energy storage are introduced, providing guidelines for developing inks that match well with the present printing techniques. Last, but not least, we also propose the perspectives on the development of 2 D materials‐based inks for energy‐storage applications.
