| dc.description.abstract | This study provides a new strategy for the synthesis of a cost-effective, highly ionic, and highly water uptake ampholytic polymer that is soluble in common organic solvents. The first series of ampholytic polymer, PAMPSIm, was prepared by UV-initiated free-radical polymerization of anionic monomer, 2-acrylamido-2-methylpropane sulfonic acid (AMPS), and cationic monomer 1-hexyl-3-methyl imidazolium (Vim6C). Via modulation of the ratio of anion and cation monomers, PAMPSIm has been successfully synthesized with the molar ratios of 30%, 50% and 70% of AMPS monomers. The theoretical ion exchange capacity (IEC) has been calculated and reached up to 4.49 meq/g with a greater water uptake of 356%. All PAMPSIm series polymers are soluble and good film-forming in methanol
The second two series of copolymer, PAMPSEO and PAMPSEO3, were prepared by polymerization of AMPS with hydroxyl ethyl acrylate (HEA) and ethoxyethoxy ethyl acrylate (Agisyn™ 2880), respectively. Further, these copolymers were lithiated to obtain their corresponding lithium salts, PAMPSEOLi and PAMPSEO3Li, to serve as solid electrolytes for lithium ion batteries. Currently, the lithium ion battery performance testing of these lithiated copolymers are in progress.
