A deep eutectic solvent (DES) ionic gel is fabricated rapidly under mild conditions. The acrylic acid monomer is polymerized based on a dual self‐catalytic system between Vitamin C (VC) and metal ions, such as Fe3+ in the presence of ammonium persulfate in the DES of betaine and ethylene glycol. The as‐obtained PAA/DES ionic gel possesses excellent conductivity between 0.1 and 1.3 S m−1 in a wide range of temperatures from 0 to 90 °C. Moreover, it also shows an ultra‐stretchable performance with stretch more than 200 times its original length even under a stretching rate of 100 mm min−1. Besides, it can operate in harsh conditions because of its anti‐freezing and anti‐drying properties. The ionic gel is self‐healing, and the stretching and conductive performance can be recovered after it is broken. These superior properties of the DES ionic gel provide new insights into the design of novel gels in various applications, such as tissue engineering, sensing, and wearable electronics.

“…These limitations are usually related to the technologies employed in the realization of such devices, like screen-printing or inkjet printing, which allow only planar printings [11,[15][16][17][18][19][20][21][22]. Another alternative can be the so-called 3D-origami technique, consists of a specific paper folding to develop a final electro-device [23,24]. The advantage of this technique is at the same time a drawback and a limitation, since origami electronics devices are simple to use and develop, but they need human presence to follow the specific folding procedure, otherwise the device will be useless.…”

Printed electronics is an expanding research field that can reach the goal of reducing the environmental impact on electronics exploiting renewable and biodegradable materials, like paper. In our work, we designed and tested a new method for fabricating hybrid smart devices on cellulose substrates by aerosol jet printing (AJP) and photonic curing, also known as flash lamp annealing (FLA), capable to cure low temperature materials without any damage. Three different cellulose-based materials (chromatographic paper, photopaper, cardboard) were tested. Multilayer capability and SMDs (surface mount devices) interconnections are possible permitting high flexibility in the fabrication process. Electrical and geometrical tests were performed to analyze the behavior of printed samples. Resulted resistivities are 26.3 × 10−8 Ω⋅m on chromatographic paper, 22.3 × 10−8 Ω⋅m on photopaper and 13.1 × 10−8 Ω⋅m on cardboard. Profilometer and optical microscope evaluations were performed to state deposition quality and penetration of the ink in cellulose materials (thicknesses equal to 24.9, 28.5, and 51 μm respectively for chromatographic paper, photopaper, and cardboard). Furthermore, bending (only chromatographic paper did not reach the break-up) and damp environment tests (no significant variations in resistance) where performed. A final prototype of a complete functioning multilayer smart devices on cellulose 3D-substrate is shown, characterized by multilayers, capacitive sensors, SMDs interconnections.

“…Li Ren’ai et al [ 67 ] have also used photopolymerized AA:ChCl eutectics to prepare conductive paper [ 67 ] and strain sensors [ 68 ]. Two:one mixtures of AA and ChCl were prepared and photopolymerized in the presence of ethylene glycol diacrylate as cross-linker (1–5% w / w /relative to DES) and 2-hydroxy-4-(2-hydroxyethoxy)-2-methylpropiophenone (Irgacure 2959 ® ) as photoinitiator (2% w / w relative to DES).…”

Deep eutectic solvents (DESs) represent an emergent class of green designer solvents that find numerous applications in different aspects of chemical synthesis. A particularly appealing aspect of DES systems is their simplicity of preparation, combined with inexpensive, readily available starting materials to yield solvents with appealing properties (negligible volatility, non-flammability and high solvation capacity). In the context of polymer science, DES systems not only offer an appealing route towards replacing hazardous volatile organic solvents (VOCs), but can serve multiple roles including those of solvent, monomer and templating agent—so called “polymerizable eutectics.” In this review, we look at DES systems and polymerizable eutectics and their application in polymer materials synthesis, including various mechanisms of polymer formation, hydrogel design, porous monoliths, and molecularly imprinted polymers. We provide a comparative study of these systems alongside traditional synthetic approaches, highlighting not only the benefit of replacing VOCs from the perspective of environmental sustainability, but also the materials advantage with respect to mechanical and thermal properties of the polymers formed.
