{"product_id":"cgpecmdmaa","title":"DMAA (N,N-Dimethylacrylamide, \u003e99.5%) as Crosslinking Monomer for Gel Polymer Electrolytes (GPEs), 50-200 g\/bottle, CGPECMDMAA","description":"\u003cp\u003eDMAA (N,N-Dimethylacrylamide) is a highly polar, reactive monofunctional vinyl monomer featuring a tertiary amide group attached to an activated acrylic backbone. While multifunctional crosslinkers establish 3D network connectivity, DMAA is utilized in advanced energy storage research as a premier functional co-monomer and reactive solvent for Gel Polymer Electrolytes (GPEs)—particularly in aqueous, polar aprotic, and high-voltage lithium\/sodium metal battery systems—offering rapid polymerization kinetics and exceptional alkali metal ion coordination.\u003c\/p\u003e\n\u003cp\u003eIts main features are: (1) \u003cstrong\u003eTertiary Amide Polar Core\u003c\/strong\u003e: Contains strongly electron-donating carbonyl (C=O) and tertiary amine (-N(CH3)2) groups within its amide moiety. This creates a high dipole moment that promotes strong chemical interactions with polar solvents, salt ions, and electrode surfaces. (2) \u003cstrong\u003eRapid Free-Radical Polymerization Kinetics\u003c\/strong\u003e: As an acrylamide derivative, DMAA exhibits significantly faster propagation rates during free-radical polymerization compared to standard acrylate or methacrylate monomers, enabling rapid gelation under mild thermal or UV activation. (3) \u003cstrong\u003eBroad Solvent Compatibility\u003c\/strong\u003e: Exhibits exceptional miscibility in water, polar organic solvents, and aprotic carbonate binary\/ternary blends (EC\/DEC\/DMC\/PC), preventing phase separation during polymer network formation. (4) \u003cstrong\u003eStrong Ion Solvation Capability\u003c\/strong\u003e: The oxygen and nitrogen atoms act as effective Lewis base sites that actively coordinate with lithium (Li+), sodium (Na+), or zinc (Zn^{2+}) ions, reducing effective desolvation energy and facilitating smooth ionic transport.\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003eIts main functional roles in GPEs synthesis are: (1) \u003cstrong\u003eEnhanced Ionic Conductivity via Ion-Dipole Coordination\u003c\/strong\u003e: The lone pairs on the amide oxygen and nitrogen atoms interact dynamically with charge-carrying cations, assisting in salt dissociation and promoting segmental chain motion. This ensures that DMAA-modified GPE networks maintain high room-temperature ionic conductivities routinely exceeding 10^{-3}  S\/cm. (2) \u003cstrong\u003eInterfacial Wetting \u0026amp; Adhesion\u003c\/strong\u003e: Due to its high surface polarity, DMAA thoroughly wets separator membranes (such as glass fiber, PE\/PP, or Celgard) and high-loading composite electrode microstructures (such as NCM811 or silicon anodes), eliminating interfacial voids and lowering charge-transfer resistance. (3) \u003cstrong\u003eRobust Co-Polymerization Network Modification\u003c\/strong\u003e: When copolymerized alongside multi-functional structural crosslinkers (such as HDDA, HDDMA, TPGDA, or MBAA [N,N'-Methylenebisacrylamide] in aqueous systems), DMAA introduces polar pendant groups that prevent crystalline phase separation, yielding stable, amorphous 3D gel matrices.\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ctable style=\"width: 100%;
