“…Water was chosen to be the anti-solvent used in this work, as it regenerates the dissolved cellulose at the fastest rate [ 10 ] and to the purest form, forming Cell-CNT fibers ( Scheme 1 ) over extrusion through a syringe, when compared to other anti-solvents available in the literature. Already a 1% content of water in IL-cellulose solution weakens the coordination of IL and cellulose, rendering the cellulose insoluble [ 10 , 26 ].…”

As both consumers and producers are shifting from fossil-derived materials to other, more sustainable approaches, there is a growing interest in bio-origin and biodegradable polymers. In search of bio-degradable electro-mechanically active materials, cellulose-multi wall carbon nanotube (Cell-CNT) composites are a focus for the development of actuators and sensors. In the current study, our aim was to fabricate Cell-CNT composite fibers and study their electro-mechanical response as linear actuators in aqueous and propylene carbonate-based electrolyte solutions. While the response was (expectedly) strongly solvent dependent, the different solvents also revealed unexpected phenomena. Cell-CNT fibers in propylene carbonate revealed a strong back-relaxation process at low frequencies, and also a frequency dependent response direction change (change of actuation direction). Cell-CNT fibers operated in aqueous electrolyte showed response typical to electrochemical capacitors including expansion at discharging with controllable actuation dependence on charge density. While the response was similarly stable in both electrolyte solution systems, the aqueous electrolytes were clearly favorable for Cell-CNT with 3.4 times higher conductivities, 4.3 times higher charge densities and 11 times higher strain.

“…All together these processes require suitable solvents for the dissolution of biomass based components [14]. Biomass is hard to dissolve in common organic solvents due to their complex structure and strong intrainter molecular hydrogen bonding [7]. Ionic liquids (ILs) are suitable solvents in the biorefining processes, because ILs exhibits several attractive properties such as those of solvent and also performs as a catalyst for some reactions.…”

“…Lots of reports are available on dissolution of cellulose in ILs and its applications (48,64]. Dissolution of cellulose samples in some imidazolium-based ILs, collected from references [46,[65][66][67][68][69] is available in [70]. Selected results for cellulose dissolution in ILs are presented in [4].…”
