Layer-by-layer self-assembled conductor network composites in ionic polymer metal composite actuators with high strain response

“…The LbL composite electrodes are fabricated by immersing the Nafion film into two oppositely charged solutions alternately, which contain anionic gold nanopaticles ͑ϳ2 nm diameter, Purest Colloids, Inc.͒ and the polycation poly͑allylamine hydrochloride͒, respectively. [15][16][17] The composites grow via the electrostatic attraction between polyelectrolyte or nanoparticles in solution and the oppositely charged substrate. The LbL CNCs, comprising 100 and 200 LbL bilayers, have electrode thicknesses of 0.4 and 0.8 m, respectively.…”

Ion transport and storage of ionic liquids in ionic polymer conductor network composites

“…8,13 Two ILs were examined as electrolytes, where 1-ethyl-3-methylimidazolium ͓͑EMI + ͔͒ served as the cation and tetrafluoroborate ͓͑BF 4 − ͔͒ and trifluoromethanesulfonate ͓͑Tf − ͔͒ served as the anions. 14 For the IPCNCs fabricated with the directly assembly method, either the commercial Nafion film NR-211 of thickness 25 m or Aquivion from Solvay was chosen as the spacer layer in Fig.…”

Plastic Transmissive Infrared Electrochromic Devices

“…[25,26] Recent reports on visible electrochromic devices demonstrate enhanced switching speeds achieved by increasing electrolyte conductivity and surface area and altering polymer morphology for increased accessibility of the doped polymer region to ions. [10,12,13] Optical contrast also can be maximized by optimizing the active film layer thickness. Films that are too thick result in slower dynamics and lower or plateaued optical contrasts.…”

“…and optical contrast in the visible and near infrared wavelengths as well as in device and polymer design. [10][11][12][13][14] Electrochemically doped polymer films also absorb from the mid-infrared to microwave wavelength regions of the spectrum due to the formation of charge carriers with electrochemical doping and the resulting increase in conduction. Changes in the polymer film thickness and morphology resulting from the influx of ions into the film also can contribute to the observed infrared transitions.…”
