Gelatin- and DNA-based ionic conducting membranes for electrochromic devices

Ionically conducting Er3+-doped DNA-based biomembranes for electrochromic devices

“…The color variation between blue and transparent showed a change during the test, where a decrease of the charge density from -4.0 mC.cm −2 to -1.2 mC.cm −2 was observed after 4000 color/bleaching cycles. The charge density value for the initial sweeps was higher than -1.8 mC.cm −2 at -2.5 V, reported for the ECD with DNA-based electrolytes [20], but lower than -6.6 mC.cm −2 at -3.5 V [40].…”

Formation of Multiple Structural Formats of DNA in a Bio-Deep Eutectic Solvent

“…The differential ion migration leading to differential gel swelling in response to an applied electric field in ion gels made them useful as electromechanical actuators . Although DNA is not used so far for the fabrication of ion–gels except a report on the preparation of gelatin and DNA‐based gel polymer electrolytes with high ionic conductivity by treating them with acetic acid and LiClO 4 . There is also no report on the preparation of ion–gel of DNA by interacting with ionic liquids (ILs) or deep eutectic solvents (DESs), however, ILs are being extensively used as suitable substrates for the preparation of ion–gels .…”

DNA-based ionic conducting membranes

“…Their use in smart windows was described in our preceding paper. 12 They can be also used in photovoltaic Grätzel cells for solar energy conversion. They are cheap, made principally of waste material, and their principal advantage is the ease in processing and operation is that they are solid, in contrary to the previously used liquid cells.…”

“…It has been already shown that DNA can be plasticized with glycerol, resulting in transparent membranes with good ion conducting and material processing properties. 12 The present study reports the results of electrical measurements, done in terms of impedance, phase angle, conductivity, and capacitance measurements and performed on DNA-based gel electrolytes membranes.…”
