{"product_id":"cgpecmtegdma","title":"TEGDMA (Triethylene glycol dimethacrylate, \u003e99.0%) as Crosslinking Monomer for Gel Polymer Electrolytes (GPEs), 50-200 g\/bottle, CGPECMTEGDMA","description":"\u003cp\u003eTEGDMA (Triethylene glycol dimethacrylate) (C14H22O6) is a bifunctional aliphatic methacrylate monomer featuring two reactive methacrylate groups bridged by a flexible, short oligo(ethylene glycol) ether spacer (-(CH2CH2O)3-). In advanced energy storage research, TEGDMA is utilized as an exceptional crosslinking agent for Gel Polymer Electrolytes (GPEs) and in situ polymerized solid\/gel battery systems, providing a favorable balance between mechanical network stability and enhanced alkali metal ion solvation.\u003c\/p\u003e\n\u003cp\u003eIts main features are: (1) \u003cstrong\u003eBifunctional Methacrylate Architecture\u003c\/strong\u003e: Features two terminal methacrylate (CH2=C(CH3)COO-) groups (f = 2) that undergo controlled free-radical polymerization to form a stable 3D polymer network. (2) \u003cstrong\u003ePEO-Like Oligo-Ether Backbone\u003c\/strong\u003e: Unlike purely aliphatic hydrocarbon spacers (such as HDDA or HDDMA), TEGDMA contains recurring ether-oxygen atoms (-C-O-C-) that structurally mimic polyethylene oxide (PEO). This local chemical environment actively assists in ion coordination and salt dissociation. (3) \u003cstrong\u003eLow Liquid Viscosity \u0026amp; Miscibility\u003c\/strong\u003e: Possesses moderate room-temperature viscosity and dissolves readily in aprotic carbonate binary\/ternary solvent blends (EC\/DEC\/DMC\/PC) and liquid monomer mixtures, ensuring thorough infiltration of porous separator membranes and electrode pores prior to curing. (4) \u003cstrong\u003eOptimized Chain Flexibility\u003c\/strong\u003e: The flexible triethylene glycol chain provides higher conformational mobility than shorter dimethacrylates (like EGDMA), lowering the glass transition temperature (Tg) and preventing excessive network brittleness during cycling.\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003eIts main features are: (1) \u003cstrong\u003eRigid 3D Network \u0026amp; Complete Liquid Immobilization\u003c\/strong\u003e: DPHA rapidly copolymerizes into a tight, highly branched mesh that permanently traps and immobilizes organic liquid electrolytes (EC\/DEC\/DMC\/PC), completely eliminating free-flowing liquid leakage and suppressing solvent volatility. (2) \u003cstrong\u003eSuperior Mechanical Dendrite Suppression\u003c\/strong\u003e: Because soft, flexible linear polymer matrices can sometimes lack the high shear modulus required to physically block aggressive lithium or sodium dendrite growth, incorporating DPHA as a high-density crosslinker substantially elevates the mechanical hardness and puncture resistance of the GPE. (3) \u003cstrong\u003eEnhanced Dimensional Stability Under Cycling\u003c\/strong\u003e: The rigid 3D architecture restrains volumetric expansion and contraction at the electrode interfaces during prolonged cycling, preventing micro-cracking and maintaining continuous interfacial contact.\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003eThe main functional roles in GPEs are: (1) \u003cstrong\u003ePermanent 3D Network \u0026amp; Liquid Immobilization\u003c\/strong\u003e: Upon thermal (using AIBN or BPO) or UV-initiated free-radical polymerization (using photoinitiators like TPO-L or BAPO), TEGDMA copolymerizes into a stable 3D mesh that permanently traps and immobilizes organic liquid electrolytes, eliminating free-flowing liquid leakage risks. (2) \u003cstrong\u003eEnhanced Ionic Conduction via Ether-Oxygen Solvation\u003c\/strong\u003e: The ether linkages within the triethylene glycol spacer participate in Lewis acid-base interactions with lithium or sodium ions (Li+\/Na+), facilitating ion hopping, reducing desolvation energy, and ensuring high room-temperature ionic conductivities routinely exceeding 10^{-3} S\/cm. (3) \u003cstrong\u003eInterfacial Wetting \u0026amp; Dimensional Stability\u003c\/strong\u003e: The low-viscosity liquid precursor thoroughly wets separator fibers and composite electrode microstructures, while the crosslinked ether-rich network maintains structural integrity and restrains volumetric fluctuations during prolonged charge-discharge cycling.\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ctable style=\"width: 100%; height: 407.238px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCGPECMTEGDMA (C-GPE-CM-TEGDMA)\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: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e109-16-0\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 132px;\"\u003e\n\u003ctd style=\"width: 28.0702%; height: 132px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 132px;\"\u003e\n\u003cp\u003e\u003cspan class=\"iNqyIf\" data-sfc-cp=\"\" data-sfc-root=\"c\"\u003e\u003cspan\u003e C\u003c\/span\u003e\u003csub\u003e14\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e22\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cbr\u003e\u003c!--TgQPHd|||[]--\u003e\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\/CGPECMTEGDMA_structure_160x160.jpg?v=1793584146\" 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: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan class=\"iNqyIf\" data-sfc-cp=\"\" data-sfc-root=\"c\"\u003e286.2 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: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan class=\"iNqyIf\" data-sfc-cp=\"\" data-sfc-root=\"c\"\u003eColorless liquid\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: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003ePurity \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan class=\"iNqyIf\" data-sfc-cp=\"\" data-sfc-root=\"c\"\u003e\u0026gt;99.0%\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: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003eDensity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan class=\"iNqyIf\" data-sfc-cp=\"\" data-sfc-root=\"c\"\u003e1.092 g\/mL\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: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003eBoling Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003e170-172 °C\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.0375px;\"\u003e\n\u003ctd style=\"width: 28.0702%; height: 26.0375px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 26.0375px;\"\u003e50 g, 100 g, and 200 g\/bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the TEGDMA liquid in a dry place and dark 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\u003cspan\u003e\u003ca href=\"https:\/\/pubs.acs.org\/aelccp\/article\/10\/4\/1953\/3757322\"\u003eX.
