{"product_id":"cgpemmma","title":"MMA {Methyl methacrylate} as Crosslinking Monomer for Gel Polymer Electrolyte, 100 g\/bottle, CGPEMMMA","description":"\u003cp\u003eUsing Methyl Methacrylate (MMA) monomer to formulate Gel Polymer Electrolytes (GPEs) is one of the most effective paths toward achieving seamless interfacial contact in next-generation solid-state or quasi-solid-state systems. By injecting a low-viscosity liquid precursor (MMA monomer + liquid electrolyte + initiator) directly into the cell and polymerizing it in situ, you effectively eliminate the high interfacial resistance that usually plagues pre-cast ex-situ membranes.  \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIn-Situ Polymerization Mechanism\u003c\/strong\u003e: The typical synthesis relies on thermal- or UV-initiated free-radical polymerization. The liquid precursor thoroughly wets the porous separator and penetrates the tortuous porosity of both the cathode and anode before curing. (1) \u003cem\u003ePrecursor Feed\u003c\/em\u003e: MMA monomer, a lithium or sodium salt (e.g., LiFSI, NaFSI, LiPF6), a plasticizing organic solvent\/ionic liquid, and a radical initiator like AIBN or V-65. (2) \u003cem\u003eReaction\u003c\/em\u003e: Upon heating (typically 60–70°C) or UV exposure, the vinyl groups (C=C) in the MMA monomers undergo chain-growth polymerization to yield linear or highly entangled Polymethyl Methacrylate (PMMA) chains trapping the liquid phase. \u003c\/p\u003e\n\u003cp\u003eThe core advantages of MMA-based GPEs are: (1) \u003cstrong\u003eCarbonyl Coordination\u003c\/strong\u003e: The strong polar carbonyl groups (C=O) and ester groups (-OCH3) along the PMMA backbone interact strongly with the organic solvents, ensuring an exceptionally high electrolyte uptake and low solvent leakage. (2) \u003cstrong\u003eSalt Dissociation\u003c\/strong\u003e: These oxygen-rich groups help coordinate with the metal cations (Li+ or Na+), facilitating the dissociation of ion pairs and improving both ionic conductivity (often reaching 10^{-3} S cm-1 at room temperature) and the cation transference number. (3)\u003cstrong\u003e Interfacial Super-Wetting\u003c\/strong\u003e: Because it polymerizes directly inside the active layers, the resulting gel offers an uninterrupted path for ion transport, drastically cutting down interfacial resistance. (4) \u003cstrong\u003eRadical Resistance\u003c\/strong\u003e: PMMA exhibits unique chemical resilience against nucleophilic attack from intermediate species (such as superoxide radicals in Li-O2 chemistries), making it highly stable compared to conventional polyethers.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 310.65px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6875px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 47.6875px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 47.6875px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCGPEMMMA (C-GPE-M-MMA)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 10px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 10px;\"\u003e\n\u003cp\u003e\u003cspan\u003e80-62-6\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 155.725px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 155.725px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 155.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003e(H\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003eC=CHCO\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003eCH\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003e)\u003c\/span\u003e\u003csub\u003e4\u003c\/sub\u003e\u003cspan\u003eC\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CGPEMMMA_chemical_structure_100x100.jpg?v=1783275177\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e100.12 g\/mol\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003eDensity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e0.936 g\/mL at 25 °C (lit.)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.0576%;\"\u003e\u003cem\u003eBoling Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%;\"\u003e\n\u003cp\u003e100 °C (lit.)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.0375px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 26.0375px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 26.0375px;\"\u003e100 g\/bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the MMA monomer in a dry place. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0013468606006207\"\u003e\u003cspan\u003eK.
