Abstract:	本論文提供一快速、低成本、高離子含量、高吸水性並可使用常用溶劑即可進行溶解之兩性離子聚合物之合成策略。首先使用2-丙烯醯胺基-2-甲基丙磺酸 (2-acrylamido-2-methylpropane sulfonic acid, AMPS ) 與1-乙烯基-3-己基咪唑溴鹽(1-hexyl-3-vinylimidazolium bromide, Vim6C) 為陰、陽離子單體，製備第一系列兩性離子聚合物-PAMPSIm。藉由調控陰、陽離子單體莫耳比，可開發出不同離子比例之離子高分子。目前PAMPSIm已成功分別合成出AMPS莫耳百分比為 30%、50%、70% 之比例。此系列高分子具有極高之離子交換容量最高可達4.49 meq/g，同時此新開發之離子高分子皆能溶於甲醇，成膜後展現極高之吸水膨潤比 (356%)。另以2-丙烯醯胺基-2-甲基丙磺酸( AMPS )與丙烯酸羥乙酯( HEA )及乙氧基乙氧基乙基丙烯酸酯( Agisyn™ 2880 )開發第二系列共聚物PAMPSEO，目前鋰化後所得含鋰離子之PAMPSEOLi系列高分子，可作為鋰離子電池之固態電解質。此系列高分子已送往合作實驗室進行摻雜製備電池元件，等待後續電池效能檢測。 ;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.
