Composition and method for retention of solvated compounds and ions
Storage stable polyhydroxylated aromatic ether adducts of polyalkylene oxide are described. Reactive compositions are formed by combining an ether adduct with an aldehyde, optionally further adding a phenolic-aldehyde prepolymer. The reactive compositions are cured by removing water, by acidification, or both. The cured compositions sorb solvated compounds from environments containing water. The cured compositions are also useful for pre-loading with compounds that are subsequently released at a controlled rate into environments containing water.
DRY GEL POLYMER ELECTROLYTES
Dry gel polymer electrolytes as well as their methods of manufacture and use in electrochemical cells are disclosed. In some embodiments, a dry gel polymer electrolyte may include sulfolane, a high molecular weight polyethylene oxide, and a lithium salt. In embodiments in which the dry gel polymer electrolyte is included in the electrochemical cell, at least one layer of the dry gel polymer electrolyte may be disposed between an anode and a cathode of the electrochemical cell.
