“…The candidate technologies mainly include photolithography, laser direct writing, nanoimprinting, electroplating, electroless plating, scraping, cracking, and gravure printing. [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45] These hybrid manufacturing processes greatly help improve the performance of FTEs with embedded metal mesh. Shen and co-workers demonstrated that silver colloidal nanoparticles could be successfully scraped into the microgrooves fabricated by photolithography or laser direct writing to form embedded metal mesh, and they reached the stage of commercial fabrication.…”

performance, transparent conductive oxides, as represented by indium tin oxide (ITO), have been mostly used widely for transparent electrodes (TEs) in the past few decades. However, the inherent properties of ITO such as brittleness and poor flexibility hinder its applications for flexible and stretchable optoelectronic products. [10] Hence, many alternatives to ITO have been developed to address these challenges for the next generation of FTEs, such as graphene, [11] carbon nanotubes, [12,13] conductive polymers, [14][15][16][17][18] transparent thin metal films, [19,20] random metal nanowires, [2,21] regular metalmesh, [22,23] and hybrid materials. [24,25] Among these FTEs, metal-mesh possesses excellent mechanical flexibility and optoelectronic properties. In particular, the trade-off between low sheet resistance and the high transmittance of TEs can be parametrically designed and further optimized by simply changing the line width, pitch, aspect ratio (AR), shape, and arrangement of the mesh. The metal mesh can be fabricated with a low-cost and large-area manufacturing process (such as solution-process), which can be carried out in a vacuum-free environment and usually requires only a low temperature process. [26][27][28][29][30] So far, FTEs based on metal mesh Flexible transparent electrodes (FTEs) with an embedded metal mesh are considered a promising alternative to traditional indium tin oxide (ITO) due to their excellent photoelectric performance, surface roughness, and mechanical and environmental stability. However, great challenges remain for achieving simple, cost-effective, and environmentally friendly manufacturing of high-performance FTEs with embedded metal mesh. Herein, a maskless, templateless, and plating-free fabrication technique is proposed for FTEs with embedded silver mesh by combining an electric-field-driven (EFD) microscale 3D printing technique and a newly developed hybrid hot-embossing process. The final fabricated FTE exhibits superior optoelectronic properties with a transmittance of 85.79%, a sheet resistance of 0.75 Ω sq −1 , a smooth surface of silver mesh (R a ≈ 18.8 nm) without any polishing treatment, and remarkable mechanical stability and environmental adaptability with a negligible increase in sheet resistance under diverse cyclic tests and harsh working conditions (1000 bending cycles, 80 adhesion tests, 120 scratch tests, 100 min ultrasonic test, and 72 h chemical attack). The practical viability of this FTE is successfully demonstrated with a flexible transparent heater applied to deicing. The technique proposed offers a promising fabrication strategy with a cost-effective and environmentally friendly process for high-performance FTE.

“…At frequencies of 1 GHz and higher, the discrepancy with the continuous layer model increases, as shown in Figure 12c. In the microwave region, even the most low-resistance coatings with sheet resistance less than 0.1 Ω/sq have an SE value of no more than 40-45 dB [21,23].…”

“…Additional electroless deposition of Cu on Ag nanowire seed contributes to a dramatic increase in SE for a wide frequency range [17]. Lithographic micro and nanomeshes, also widely presented in the literature, demonstrate high optoelectric parameters and SE: Ag ring micromesh [18], Cu square nanomesh [19], Cu-Ni square micromesh [20] and Ag-Ni stochastic micromesh [21]. Recently, much attention has been paid to obtaining micro and nanomesh coatings based on self-organization processes.…”

“…The following solutions can be cited as example: cracked template Ag mesh [22] and Cu-Ag; Ni-Ag meshes [23]; and Ag nanoparticle mesh emulsion template [24]. An important feature of the cracked template is the non-periodic mesh structure; therefore, in a multilayer version, the system will not have a moiré pattern [21,23], which is typical for the imposition of periodic meshes [19].…”

Embedded copper mesh coatings with low sheet resistance and high transparency were formed using a low-cost Cu seed mesh obtained with a magnetron sputtering on a cracked template, and subsequent operations electroplating and embedding in a photocurable resin layer. The influence of the mesh size on the optoelectric characteristics and the electromagnetic shielding efficiency in a wide frequency range is considered. In optimizing the coating properties, a shielding efficiency of 49.38 dB at a frequency of 1 GHz, with integral optical transparency in the visible range of 84.3%, was obtained. Embedded Cu meshes have been shown to be highly bending stable and have excellent adhesion strength. The combination of properties and economic costs for the formation of coatings indicates their high prospects for practical use in shielding transparent objects, such as windows and computer monitors.

“…Many of the fillers that are being used in these polymer composite include carbon nanotubes which are known to have exceptionally high electrical conductivity. Other fillers include particles which have been coated with silver, metal fibres, and carbon particles [15,[43][44][45][46]. Many of the studies conducted on the fabrication of EMI shielding materials have shown that for high SE, a good conducting network needs to be present within the material.…”

Polymer matrix composites have generated a great deal of attention in recent decades in various fields due to numerous advantages polymer offer. The advancement of technology has led to stringent requirements in shielding materials as more and more electronic devices are known to cause electromagnetic interference (EMI) in other devices. The drive to fabricate alternative materials is generated by the shortcomings of the existing metallic panels. While polymers are more economical, easy to fabricate, and corrosion resistant, they are known to be inherent electrical insulators. Since high electrical conductivity is a sought after property of EMI shielding materials, polymers with fillers to increase their electrical conductivity are commonly investigated for EMI shielding. Recently, composites with nanofillers also have attracted attention due to the superior properties they provide compared to their micro counterparts. In this review polymer composites with various types of fillers have been analysed to assess the EMI shielding properties generated by each. Apart from the properties, the manufacturing processes and morphological properties of composites have been analysed in this review to find the best polymer matrix composites for EMI shielding.
