Ionic liquids are increasingly attracting the attention of researchers in both academia and industry. However, research into ionic liquids is mainly limited in chemistry, and the electromagnetic characteristics and microfluidic/optofluidic applications of ionic liquids have been rarely studied. Here, ionic liquids are used as a new type of fluid material for microfluidics/optofluidics, and the research...
Ionic liquid-polymer gel microstructures with high spatial resolution (line widths of 35 – 40 µm), good electrical conductivity (5 – 30 mS/cm), optical transparency and mechanical flexibility are fabricated using a new and solvent-free inkjet printing process. Homogeneously gelled structures are achieved by carrying out the printing and polymerization process in nitrogen atmosphere eliminating the...
Four ionic liquids (ILs), trihexyl (tetradecyl) phosphonium methanesulfonate ([mes-]), trihexyl (tetradecyl) phosphonium dodecylbenzenesulfonate ([dbs-]), trihexyl (tetradecyl) phosphonium chloride([Cl-]) and tetrabutyl phosphonium methanesulfonate ([tbt+]), were chosen to add to plasticized poly(vinyl chloride) (PVC) gels for improving actuation behavior at low electric fields. It was found that...
Carbon nanotubes have electrical and mechanical properties that make them highly attractive for actuators. They have the ability to deform elastically by several percent, thus storing very large amounts of energy, thanks to their crystalline nature and to their morphology. We investigate the performance of a bimorph actuator composed of multi-walled carbon nanotubes (MWCNTs), polyvinylidene difluoride...
