“…It consists in the polymerization of monomers through electrochemical induction that leads to the formation of conductive polymers, normally in the form of electrodeposited films [35]. An interesting feature of using DES as media for electropolymerization is its influence in the polymer formation and its final characteristics [36,37]. This type of polymerization is one of the first applications of DES, reported in the 1980s, as stated by Fernandes et al in their article about polyaniline (PANI) electrosynthesis in DES.…”

“…Using the same DES systems, Prathish et al published the electropolymerization of poly(3,4-ethylenedioxythiophene) (PEDOT), with better results of stability and sensitivity for the PEDOT prepared from choline chloride:urea DES. The shape, size, surface, electrocatalytic, and sensing properties of the PEDOT films were highly influenced by the DES used [37,39]. The most recent study reported on this topic, from Zou and Huang, also focused the electrodeposition of PANI from DES.…”

The green and versatile character of deep eutectic solvents (DES) has turned them into significant tools in the development of green and sustainable technologies. For this purpose, their use in polymeric applications has been growing and expanding to new areas of development. The present review aims to summarize the progress in the field of DES applied to polymer science and engineering. It comprises fundamentals studies involving DES and polymers, recent applications of DES in polymer synthesis, extraction and modification, and the early developments on the formulation of DES–polymer products. The combination of DES and polymers is highly promising in the development of new and ‘greener’ materials. Still, there is plenty of room for future research in this field.

“…In the doping step, the anions of the acid solutions (perchlorate ions, chloride ions, nitrate ions, sulfate ions and acetate ions), PSS and the sulfate ions from the oxidant all acted as the doping agents 30 and were incorporated into the PEDOT chains during polymerization. 2,31 Moreover, sodium ions from the oxidant interacted with the PSS chain to form PSSNa during polymerization 32 as shown in Scheme 1.…”

The poly (3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS) synthesis conditions were refined to obtain extremely high electrical conductivity. PEDOT:PSS was synthesized by chemical oxidative polymerization under the effects of acid types and concentrations, EDOT:PSS weight ratio, and surfactant types and concentrations. The PEDOT:PSS synthesized with EDOT:PSS weight ratio of 0.5:5.5 in 0.1 mol L −1 HClO 4 provided the highest electrical conductivity of 1.04 × 10 4 ± 188 S cm −1 , not previously reported. The enhanced electrical conductivity can be attributed to the combinatorial primary doping by selective ions (ClO 4 − , PSS − , SO 4 2−) generating a suitable PEDOT:PSS structure with high carrier number and electron mobility, as consistently verified using Fourier transform infrared spectroscopy, UV-visible spectrometry, X-ray photoelectron spectrometry and thermogravimetric analysis. The refined synthesis opens a new route for PEDOT:PSS nanoparticles to be used in various electronic applications which require the starting nontoxic organic material to be highly conductive.

“…Brett’s group has reported the synthesis of poly(3,4-ethylenedioxythiophene) (PEDOT) by electrochemical means in DES systems [ 97 , 98 ]. Electropolymerization of 10 mM solutions of EDOT was performed in ethaline, glyceline and reline in the presence of 4 M HClO 4 to form uniform films on glassy carbon electrodes.…”

Greener, Faster, Stronger: The Benefits of Deep Eutectic Solvents in Polymer and Materials Science

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.
