“…This high variability in properties gives rise to a similarly high amount of utility. Carbon allotropes such as Graphene and Carbon nanotubes pose interesting properties in surface areas, tensile strength, low density, stretchability, thermal conductivity, current density, gas impermeability, and overall electrical properties [ 2 , 3 , 4 , 5 , 6 , 7 ]. An outline of the important properties and potential uses is seen in Figure 1 .…”

“…Printability determines the finished print quality in terms of porosity, surface finish, and resolution of geometry. The determination of ideal printability requires tailored rheological properties while maintaining the intended properties of the novel carbon particles [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ].…”

As the industry and commercial market move towards the optimization of printing and additive manufacturing, it becomes important to understand how to obtain the most from the materials while maintaining the ability to print complex geometries effectively. Combining such a manufacturing method with advanced carbon materials, such as Graphene, Carbon Nanotubes, and Carbon fibers, with their mechanical and conductive properties, delivers a cutting-edge combination of low-cost conductive products. Through the process of printing the effectiveness of these properties decreases. Thorough optimization is required to determine the idealized ink functional and flow properties to ensure maximum printability and functionalities offered by carbon nanoforms. The optimization of these properties then is limited by the printability. By determining the physical properties of printability and flow properties of the inks, calculated compromises can be made for the ink design. In this review we have discussed the connection between the rheology of carbon-based inks and the methodologies for maintaining the maximum pristine carbon material properties.

“…32 A good layer quality is only achieved if the ink viscosity is adapted to a particular printing technique. 33 In pad printing, the ink viscosity has an essential effect on the morphology and microstructure of printed layers. The viscosity has to be low enough to transfer the ink from the pad onto the substrates.…”

Pad printing is not a widely used printing technique, but it offers the possibility of a simple, fast, and low‐cost production of various high‐resolution electrode structures. Here, the pad‐printed reduced graphene oxide (rGO) electrodes are prepared from pad‐printable inks containing rGO powder and different concentrations of two cellulose‐based polymers: ethylcellulose and cellulose acetate butyrate. The applicability of rGO inks for pad printing is analyzed according to their rheological parameters and printability. Based on viscosity, storage (G′) and loss modulus (G″) values, 10 wt% of ethylcellulose and 15 wt% of cellulose acetate butyrate appear to be most suitable for pad printing. The effect of polymer concentration on rGO electrodes homogeneity and mechanical stability is also evaluated. Cyclic voltammetry measurements for [Fe(CN)6]3−/4− redox system are performed with rGO/cellulose inks pad‐printed onto transparent conductive oxide substrates with the best results when using ethylcellulose as a binder. Finally, the square‐wave voltammetric method assesses the viability of rGO electrodes for the fast detection of ascorbic acid (detection limit of 15 μM) coupled with satisfactory precision (4.5%, n = 5) and long‐term stability during electrochemical measurements.

“…One of the technologies for the production of carbon‐functional surfaces on various substrates such as textiles and plastic films is printing. Technologies that are frequently mentioned in the literature are screen printing, ink jet printing, and gravure printing . Many positive properties of CNTs are associated to many different applications, even in the field of wind turbines, whose blades are largely made of fiber reinforced, in particular glass fiber‐reinforced, epoxy composite.…”

The performance of wind turbines suffers from icing in regions with extreme climate. One approach is to incorporate heating elements into the most susceptible areas of the wind turbine blade as protection against icing and for de‐icing. Cost‐efficient and reproducible fabrication, as well as easy integration is important due to the large area of wind turbine blades. In this work, multi‐walled carbon nanotubes are applied on a 50% poly(ethylene terephthalate) and 50% polyamide non‐woven textile substrate by rotary‐screen printing. The printed layers function as resistive heating elements in a fiber‐reinforced composite. The heating areas are provided with flexographic or screen inline‐printed silver‐electrodes and can be integrated by means of vacuum infusion into a glass fiber‐reinforced epoxy composite laminate. These laminates, which are connected to an intelligent electrical control system, are suitable for melting ice on the surface of components or for preventing the formation of ice. The first promising experiments on heating structures in a rotor blade of a wind turbine at laboratory scale (2 m length) are the basis of studies on intelligent electrical control of heating structures and their behavior at different temperatures. The heating elements were able to melt a 3–4 mm thick ice layer within 25 min in a climate chamber at −5 °C. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 45950.
