{"product_id":"cgpesmpetea","title":"PETEA {Pentaerythritol tetraacrylate} as Structural Monomer for Gel Polymer Electrolyte, 100 g\/bottle, CGPESMPETEA","description":"\u003cp\u003ePETEA—pentaerythritol tetraacrylate—as a structural monomer takes crosslinked Gel Polymer Electrolytes (GPEs) to the absolute limit of crosslink density. Armed with four highly reactive terminal acrylate groups packed around a single quaternary carbon core, PETEA is a definitive choice for building ultra-rigid, zero-leakage, and structurally unyielding 3D network hosts.\u003c\/p\u003e\n\u003cp\u003eThe core differentiator of PETEA is its compact symmetrical geometry. While ETPTA relies on elongated ethoxy spacers to grant flexibility, PETEA strips those away, leaving short, direct linkages out to its four acrylate groups. When polymerization is initiated, this tetra-functional design establishes a massive concentration of crosslinking nodes per unit volume. The resulting gel does not behave like a soft, elastic rubber; instead, it forms a highly rigid, glassy polymer network that physically locks liquid components within its sub-nanometer interstitial channels.\u003c\/p\u003e\n\u003cp\u003eThe core advantages of PETEA-based GPEs are: (1) \u003cstrong\u003eCritical Vapor Pressure Suppression (Anti-Gassing)\u003c\/strong\u003e: In high-energy-density cells operating under harsh conditions (high voltage or high ambient temperatures), liquid carbonate solvents like linear dimethyl carbonate (DMC) or ethyl methyl carbonate (EMC) exert high vapor pressures. This leads to severe gas evolution and pouch cell swelling. The ultra-dense macromolecular cages of cured PETEA exert intensive capillary and physical confinement forces on the solvent molecules. This significantly lowers the volatility and vapor pressure of the encapsulated organic solvents, allowing stable operation up to 70°C to 80°C with practically zero cell swelling or solvent \"sweating.\" (2) \u003cstrong\u003eElite Mechanical Modulus for Metal Anodes\u003c\/strong\u003e: To suppress the propagation of lithium or sodium dendrites, the electrolyte matrix needs a massive local shear modulus. While standard thermoplastic GPEs (like PVDF-HFP) yield a soft matrix that dendrites can easily pierce, a fully cured PETEA network creates a robust mechanical wall. It structurally resists the localized mechanical stress exerted by migrating dendrite tips, forcing the metal deposition at the anode to flatten out into a uniform, planar morphology. (3) \u003cstrong\u003eSevere Reduction of Free Solvent Reactivity\u003c\/strong\u003e: At high states of charge (above 4.5 V), \"free\" uncoordinated liquid solvent molecules undergo rapid oxidative decomposition at the cathode surface. Because PETEA tightly binds and confines the local solvent clouds within its dense 3D matrix, it drastically reduces the population of completely free, bulk solvent molecules. This significantly elevates the anodic stability window, allowing long-term cycling compatibility with aggressive, high-voltage cathodes.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 336.25px;\"\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\u003eCGPESMPETEA (C-GPE-SM-PETEA)\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\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e4986-89-4\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\/CGPESMPETEA_chemical_structure_160x160.jpg?v=1783238848\" 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\u003e352. 34 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\u003e1.19 g\/mL at 25 °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 PETEA 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\u003cspan\u003e\u003ca href=\"https:\/\/pubs.rsc.org\/ta\/article-abstract\/5\/35\/18888\/587314\/A-dual-functional-gel-polymer-electrolyte-for?redirectedFrom=fulltext\"\u003eX, Li, et al.
