In this paper, a highly transparent, low sheet resistance copper network film fabricated by a crack template, which made by drying an acrylic based colloidal dispersion. The fabricated copper network film shows excellent optoelectronic performances with low sheet resistance of 13.4 Ω/sq and high optical transmittance of 93% [excluding Polyethylene terephthalate (PET) substrate] at 550 nm. What’s more, the surface root mean square of the copper network film is about 4 nm, and the figure of merit is about 380. It’s comparable to that of conventional indium tin oxide thin film. The repeated bending cycle test and adhesive test results confirm the reliability of the copper network film. As a transparent conductive film, the copper network film was used as an anode to prepare organic light-emitting diode (OLED). The experiment results show that the threshold voltage of the OLED is less than 5 V and the maximum luminance is 1587 cd/m2.

“…In this regard, many representative technical solutions for the manufacture of high performance metal mesh-based TGHs have been proposed, such as photolithography and electroplating, laser direct writing and selective ablation electrodeposition, template crack, laser-induced forward transfer and hybrid manufacturing processes, etc. [35][36][37][38][39][40][41][42][43][44] These technologies have contributed significantly to the development of transparent heaters, which provide the technical basis for industrial production. For example, Cheong et al [45] fabricated a transparent electrode with R s = 0.1-0.3 Ω sq −1 and a transmittance over 82% for automobile windshield heater through photolithographic composite electroplating process.…”

Transparent glass with metal mesh is considered a promising strategy for high performance transparent glass heaters (TGHs). However, the realization of simple, low‐cost manufacture of high performance TGHs still faces great challenges. Here, a technique for the fabrication of high performance TGHs is proposed using liquid sacrificial substrate electric‐field‐driven (LS‐EFD) microscale 3D printing of thick film silver paste. The liquid sacrificial substrate not only significantly improves the aspect ratio (AR) of silver mesh, but also plays a positive role in printing stability. The fabricated TGHs with a line width of 35 µm, thickness of 12.3 µm, and pitch of 1000 µm exhibit a desirable optoelectronic performance with sheet resistance (Rs) of 0.195 Ω sq−1 and transmittance (T) of 88.97%. A successful deicing test showcases the feasibility and practicality of the manufactured TGHs. Moreover, an interface evaporator is developed for the coordination of photothermal and electrothermal systems based on the high performance TGHs. The vapor generation rate of the device reaches 10.69 kg m−2 h−1 with a voltage of 2 V. The proposed technique is a promising strategy for the cost‐effective and simple fabrication of high performance TGHs.

“…However, the ITO is not favorable in flexible electronic devices due to its intrinsic brittleness. Invisible metal-grid electrodes have been suggested as an alternative material for ITO replacement [10][11][12][13][14]. The metal-grid electrodes become very valuable if the grid electrodes are able to be fabricated by simple printing processes at lower costs since the printing methods help to improve the efficiency of material utilization [15][16][17].…”

Invisible Ag-grid transparent electrodes at a line width of the Ag-grid of 5 µm, spacing between the grid lines of 150 µm and a line thickness of 0.6 µm have been prepared on a 50 µm thick flexible polyethylene naphthalate (PEN) film substrate by a conventional gravure offset printing using our newly developed Ag nanoparticle ink. Furthermore, the Ag-grid electrode was laminated with a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) layer. The Ag-grid laminated with PEDOT:PSS (Ag-grid/PEDOT) transparent electrode was applied to a commercial alternating-current powder electroluminescent device (ACPELD) as an ITO replacement. The as-prepared Ag-grid/PEDOT-based ACPELD shows uniform luminescence with a luminance of 292 cd m −2 at 150 V 0-p and 2 kHz. Repeated bending durability of the fabricated ACPELD was evaluated by a cyclic bending test at a bending radius of 1.5 mm up to 20 000 bending cycles. Luminance of the Ag-grid/PEDOT-based ACPELD is stable throughout the bending cycles compared to that of an ITO-based ACPELD. Luminance of the 20 000 cycle-bended Ag-grid/PEDOT-based ACPELD maintains 97% of that of the as-prepared. These results demonstrate that the Ag-grid/PEDOT on PEN-based ACPELDs develop stable luminance characteristics throughout the bending cycles.
