“…A 5 mm transverse coil was used with sweep width of 100 kHz and a recycle delay time of 4 s for 1 H and 7 Li, and 10 s for 13 C. The pulse lengths for 908 (P 1 ) and 1808 (P 2 ) were 13 and 26 ms for 1 H and 13 C, and 9 and 18 ms for 7 Li. An assessment of the degree of association can be made from the NMR diffusivity measurement D NMR by calculation of the Haven ratio (H R ).…”

“…[6] In recent research, [7] a polyelectrolyte gel based on a copolymer of a neutral co-monomer, N,N 0 -dimethylacrylamide (DMAA) and a charged co-monomer, lithium 2-acrylamido-2-methyl-1-propanesulfonate (AMPSLi), chemically crosslinked with tetraethylene-glycol diacrylate (TEGDA) was prepared. The gel was polymerised in a solvent mixture of N,N-dimethylacetamide/ethylene carbonate (DMA/EC), but the disadvantage to this procedure is the introduction of a volatile component into the electrolyte.…”

Novel polymer electrolyte materials based on a polyelectrolyte‐in‐ionic‐liquid principle are described. A combination of a lithium 2‐acrylamido‐2‐methyl‐1‐propanesulfonic acid (AMPSLi) and N,N′‐dimethylacrylamide (DMMA) are miscible with the ionic liquid, 1‐ethyl‐3‐methylimidazolium dicyanamide (EMIDCA). EMIDCA has remarkably high conductivity (≥ 2 · 10−2 S · cm−1) at room temperature and acts as a good solvating medium for the polyelectrolyte. At compositions of AMPSLi less than or equal to 75 mol‐% in the copolymer (P(AMPSLi‐co‐DMAA)), the polyelectrolytes in EMIDCA are homogeneous, flexible elastomeric gel materials at 10 − 15 wt.‐% of total polyelectrolyte. Conductivities higher than 8 · 10−3 S · cm−1 at 30 °C have been achieved. The effects of the monomer composition, polyelectrolyte concentration, temperature and lithium concentration on the ionic conductivity have been studied using thermal and conductivity analysis, and pulsed field gradient nuclear magnetic resonance techniques.Comparison of the measured and calculated lithium conductivity at 30 °C.magnified imageComparison of the measured and calculated lithium conductivity at 30 °C.

“…17 PAMPS membranes have been used as ion exchange membranes, [18][19][20] humidity sensors, 21 nanofiltration films, 22 and polymer electrolytes in fuel cells. 23 However, PAMPS is mechanically weak and undesirably swelled in aqueous solutions.…”

Polymer-filled nonwoven membranes were prepared by filling the open pores of nylon nonwovens with poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS). PAMPS was synthesized via radical polymerization and crosslinked to prevent its dissolution in water. PAMPS-filled nylon nonwoven membranes showed enhanced dimensional stability and mechanical properties when compared with PAMPS membranes without nonwovens. The conductivities of PAMPS-filled nylon nonwovens were slightly lower than those of PAMPS membranes. Compared with PAMPS membranes without nonwoven hosts, both linear and crosslinked PAMPS-filled nylon nonwoven membranes exhibited lower vapor permeabilities for water, methanol, acetone, and dimethyl methylphophonate (DMMP). In addition, crosslinked PAMPS-filled nonwoven membranes presented high permselectivity on DMMP over water, which is critical for chemical protection application.

“…This is presumably a result of the strong electrostatic interaction between the lithium and the sulfonate group on the polymer backbone which requires a highly polar solvent capable of strongly interacting with the lithium cation. More recently copolymers containing the LiAMPS monomer component have been explored [10,12] which allows separation of the charged groups on the backbone, and this approach has allowed the use of more traditional battery compatible plasticizers such as ethylene carbonate (EC) and N,N9-dimethylacetamide (DMA). Travas-Sejdic and coworkers [10) have shown that conductivities of more than 10 -3 S/cm at 298 K could be achieved by fine tuning of the composition of the electrolyte.…”
