{"product_id":"cgpecmeoeoea","title":"EOEOEA {2-(2-Ethoxyethoxy)ethyl acrylate, \u003e99.0%} as Crosslinking Monomer for Gel Polymer Electrolytes (GPEs), 50-200 g\/bottle, CGPECMEOEOEA","description":"\u003cp\u003eEOEOEA (2-(2-Ethoxyethoxy)ethyl acrylate) (C9H16O4) is a flexible, long-chain monofunctional acrylate monomer featuring an ethoxyethoxyethyl oligo(ethylene glycol) ether side chain attached to a reactive acrylate group. While multifunctional crosslinkers provide primary 3D network connectivity, EOEOEA is utilized in advanced energy storage research as a specialized, highly flexible functional co-monomer and reactive diluent for Gel Polymer Electrolytes (GPEs) and solid-state polymer electrolyte systems. It combines low liquid viscosity with PEO-like ether oxygen linkages that actively assist in alkali metal ion solvation and local chain segmental motion.\u003c\/p\u003e\n\u003cp\u003eIts main structural features are: (1) \u003cstrong\u003eOligo-Ether Side Chain Architecture\u003c\/strong\u003e: Features a recurring ether-oxygen sequence (-CH2CH2OCH2CH2OCH2CH3) that structurally mimics short segments of polyethylene oxide (PEO). This local chemical environment promotes Lewis acid-base coordination with lithium (Li+) or sodium (Na+) ions. (2) \u003cstrong\u003eLow Liquid Viscosity \u0026amp; Reactive Dilution\u003c\/strong\u003e: Possesses very low room-temperature viscosity and high boiling characteristics, functioning as an efficient reactive diluent that dissolves readily in aprotic carbonate binary\/ternary solvent blends (EC\/DEC\/DMC\/PC) and thoroughly wets porous separator membranes (glass fiber, PE\/PP) and dense electrode microstructures prior to curing. (3) \u003cstrong\u003eExceptional Chain Flexibility \u0026amp; Low Tg\u003c\/strong\u003e: The flexible ethoxyethoxyethyl tail imparts a very low glass transition temperature (Tg) to the resulting polymer chains, enhancing amorphous domain mobility and preventing embrittlement during prolonged charge-discharge cycling. (4) \u003cstrong\u003eRapid Acrylate Polymerization Kinetics\u003c\/strong\u003e: As an acrylate derivative, EOEOEA exhibits fast free-radical propagation rates under thermal or UV activation, ensuring efficient copolymerization into the growing 3D polymer network.\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\u003eEnhanced Ionic Conduction via Ether-Oxygen Solvation\u003c\/strong\u003e: The ether linkages within the ethoxyethoxyethyl side chain act as electron-donating coordination sites that interact dynamically with charge-carrying cations. This assists in salt dissociation, lowers desolvation energy, and promotes segmental chain motion, ensuring that EOEOEA-modified GPE networks maintain high room-temperature ionic conductivities routinely exceeding 10^{-3} S\/cm. (2) \u003cstrong\u003eSuperior Interfacial Wetting \u0026amp; Adhesion\u003c\/strong\u003e: Due to its low surface tension and high polarity, EOEOEA radically improves the wetting behavior of liquid electrolyte precursors on high-loading composite cathodes (such as NCM811) and alkali metal anodes, minimizing interfacial resistance and eliminating dry-out. (3) \u003cstrong\u003eCopolymerization Network Modification \u0026amp; Stress Relief\u003c\/strong\u003e: Because EOEOEA is monofunctional (f = 1), it cannot form a 3D network on its own. When copolymerized alongside multi-functional structural crosslinkers (such as HDDA, DPGDA, THEICTA, or DPHA) and ion-conducting macromers (like PEGMA or host polymers such as PVDF-HFP), it acts as a flexible spacer that relieves internal mechanical stress and prevents micro-cracking during electrode volume fluctuations.\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\u003eCGPECMEOEOEA (C-GPE-CM-EOEOEA)\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\u003e7328-17-8\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 C₉H₁₆O₄\u003c\/span\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\/CGPECMEOEOEA_structure_100x100.jpg?v=1793588324\" 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\"\u003e188.22 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\"\u003e1.03 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\u003eViscosity\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;\"\u003e3-10 cps\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 EOEOEA 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\u003ca href=\"https:\/\/advanced.onlinelibrary.wiley.com\/doi\/abs\/10.1002\/adfm.202307248\"\u003e\u003cspan\u003eC.
