“…Films made of the ferroelectric fluoropolymer poly(vinylidene fluoride‐ co ‐hexafluoropropylene) (PVDF‐HFP) film have been used to modulate the electrowetting properties of electroresponsive valves. [ 77 ] In this work, cellulose fibers were first coated with hydroxyethyl cellulose. Then, silver was printed on the paper thanks to a new ink formulation containing silver acetate stabilized with PVP.…”

In recent years, paper has become an essential substrate material for developing different types of sensors, from wearable devices to single‐use test strips and biosensors. In parallel, a polymer‐based toolbox has emerged in order to add additional functions to these paper‐based analytical devices. In this article, examples are compiled from the recent literature showing microfluidic systems based on printing impermeable polymer barriers with different methods as well as the implementation of electrochemical, fluorescent, and colorimetric polymer‐based transducers in paper‐based analytical platforms. Externally actuated or dissolvable polymer valves and reservoirs, analyte concentrators, and separation devices, as well as polymer‐based recognition elements (molecularly imprinted polymers) printed on paper substrates are also reviewed. The search has revealed a plethora of possibilities for developing complex lab‐on‐chip devices implementing different polymer‐based components in them. The ability of patterning these polymers with common printing methods that do not require specialized facilities paves the way for mass producing this kind of advanced paper‐based analytical device.

“…Moreover, the introduction of metal ion precursors (Fe 3+ and Ni 2+ ) resulted in metal ions/PVP complexes on the surface of the exfoliated 2D materials. 25,26 Subsequent solvent-free drying/annealing processes facilitated the formation of binary metal oxide nanoparticles and the phase modulation of 1T-MoS 2 in the BMHNs. The electrocatalytic activities of the BMHNs were then estimated for hydrogen and oxygen production in an alkaline solution and an environmentally benign hydrogel cell, demonstrating their applicability as highperformance bifunctional heterogeneous catalysts for water splitting systems.…”

“…For example, Lee 34 et al successfully prepared highly conductive paper with aluminum features by combining aluminum precursor ink with paper through low-temperature stamping process. Sharipov 35 et al reported the stabilization of silver ions generated from reactive silver ink on paper premodified with hydroxyethyl cellulose using polyvinylpyrrolidone, which resulted in the formation of highly conductive patterned metal after annealing. Compared to other metals, copper is the most promising material for manufacturing flexible conductors because it is highly conductive and much less expensive than noble metals such as silver or gold.…”

Flexible copper conductors have been extensively utilized in flexible and wearable electronics. They can be fabricated by using a variety of patterning techniques such as vacuum deposition, photolithography, and various printing techniques. However, vacuum deposition and photolithography are costly and result in material wastage. Moreover, traditional printing inks require posttreatment, which can damage flexible substrates, or grafting polymers, which involve complex processes to adhere to flexible substrates. Therefore, this study proposes a facile method of fabricating flexible metal patterns with high electrical conductivities and remarkable bonding forces on a diverse range of flexible substrates. Catalytic ink was prepared by using a mixture of epoxy resin, copper nanopowder, and nanosilica. The ink was applied to a variety of flexible substrates, including a poly(ethylene terephthalate) (PET) film, polyimide film, and filter paper, using screen printing to establish a bridge layer for subsequent electroless deposition (ELD). The catalytic efficiency was significantly improved by treating the cured ink patterns with air plasma. The fabricated flexible metals exhibited excellent adhesion and desirable electrical conductivity. The sheet resistance of the copper layer on the PET substrate decreased to 9.2 mΩ/□ after 150 min of ELD. The resistance of the flexible metal on the PET substrate increased by only 3.125% after 5000 bending cycles. The flexible metals prepared in this study demonstrated good foldability, and the samples with filter paper and PET substrates failed after 40 and 70 folds, respectively. A pressure sensor with a bottom electrode consisting of a copper interdigital electrode on a PET substrate displayed favorable sensing performance.
