WebThe Ionic Polymer Nafion has existed since the 1960’s when DuPont developed it and found that it worked for the fuel cell industry. Ionic Polymer Metal Composites (IPMC’s), such as platinum coated Nafion, have been known to actuate when electrically stimulated since the 1990’s. The IPMC investigated needed to be hydrated to actuate and was reported to … Web10 apr. 2024 · Polymeric ionic liquids P1 and P2 were prepared via radical polymerization on M1 and M2, and the ionic conductivity of polymeric ionic liquid P2 was as high as 2.2 × 10⁻⁴ S cm⁻¹ with ...
Web13 mrt. 2015 · Ionic polymer metal composite (IPMC), of which a low actuating voltage (<5 V), high power efficiency and biocompatibility makes it a proven candidate for low power devices. However, due to its inherent nonlinear behaviour and time-variance, feedback control, as well as reliable sensing means, are required for accurate … Web14 apr. 2024 · 1. AH° hydration values become more negative as metal ion charge increases. 2. AHºhydration values become more negative as ionic potential increases. 3. Differences in ionic potential values partially explain why some cations tend to hydrolyze, whereas others only tend to hydrate. 4.

For example, iron atoms can form 2+ cations or 3+ cations. Cobalt is another element that can form more than one possible charged ion (2+ and 3+), while lead can form 2+ or 4+ cations.
Webwhere z is the electrical charge on the ion, I is the ionic strength, ε and b are interaction coefficients and m and c are concentrations. The summation extends over the other ions present in solution, which includes the ions produced by the background electrolyte. The first term in these expressions comes from Debye-Hückel theory.
