{"product_id":"cgpecmpeta","title":"PETA {Pentaerythritol triacrylate, \u003e99.0%} as Crosslinking Monomer for Gel Polymer Electrolyte, 50-200 g\/bottle, CGPECMPETA","description":"\u003cp\u003ePentaerythritol triacrylate (PETA, \u0026gt;99.0%) is a multi-functional acrylic monomer heavily utilized as a high-performance crosslinking agent in advanced Gel Polymer Electrolytes (GPEs) and in situ solidified battery systems. Because of its trifunctional molecular architecture, PETA rapidly forms a dense, highly interconnected 3D polymer network that immobilizes liquid electrolytes, completely eliminates liquid leakage, and dramatically enhances the mechanical and thermal stability of high-energy lithium and sodium battery systems.\u003c\/p\u003e\n\u003cp\u003eIts main structural and functional features are: (1) \u003cstrong\u003eChemical Structure\u003c\/strong\u003e: Features a central pentaerythritol core branching into three reactive acrylate (CH2=CHCOO-) groups. (2) \u003cstrong\u003eHigh Functionality (f = 3)\u003c\/strong\u003e: Unlike linear or bifunctional monomers (such as PEGDA or standard mono-acrylates), PETA’s tri-functionality allows it to act as an immediate branching and node-forming network builder, achieving rapid gelation and tight mesh-size control. (3) \u003cstrong\u003eSolubility \u0026amp; Reactivity\u003c\/strong\u003e: Highly soluble in standard aprotic battery solvents (EC, PC, DEC, DMC, EMC) and readily polymerizes via free-radical mechanisms using thermal initiators (e.g., AIBN, BPO) or photo-initiators (e.g., HMPP, Irgacure). (4) \u003cstrong\u003eThermal \u0026amp; Dimensional Resilience\u003c\/strong\u003e: Forms a tightly crosslinked matrix that resists thermal creep, prevents local softening at elevated cell temperatures, and safely restrains lithium dendrite growth.\u003c\/p\u003e\n\u003cp\u003eThe core advantages of PETA as monomer for GPEs are: (1) \u003cstrong\u003eRapid 3D Network Formation \u0026amp; Liquid Immobilization\u003c\/strong\u003e: Upon thermal or UV activation inside the cell stack, PETA molecules quickly crosslink into a dense, sponge-like polymer skeleton that traps and immobilizes organic liquid electrolytes. This transforms a free-flowing liquid cell into a dimensionally stable, quasi-solid-state system without sacrificing ionic pathways. (2) \u003cstrong\u003eSuppression of Polysulfide Shuttling \u0026amp; Parasitic Side Reactions\u003c\/strong\u003e: In sulfur-based or high-voltage chemistries, the dense network architecture created by PETA restricts the diffusion path of large intermediate species (such as polysulfides in Li-S systems), while protecting the electrolyte from continuous catalytic decomposition at aggressive electrode surfaces. (3) \u003cstrong\u003eEnhanced Mechanical Interfacial Contact\u003c\/strong\u003e: In situ polymerization using PETA starts from a low-viscosity liquid precursor that thoroughly wets micro-pores in separators (e.g., glass fiber or PP\/PE) and porous electrode structures. Once cured, it eliminates interfacial resistance gaps, maintaining intimate contact during volume fluctuations associated with charge-discharge cycling.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 407.45px;\" 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\u003eCGPECMPETA (C-GPE-CM-PETA)\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\u003e3524-68-3\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(H₂C=CHCO₂CH₂)₃CCH₂OH\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CGPECMPETA_Structure_160x160.jpg?v=1792869106\" 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\u003e298.3 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\u003e1.152–1.172 g\/mL at 25 °C (lit.)\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\u003eViscosity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e350–700 cP at 25°C\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\u003eGlass Transition Temperature (Tg)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e103°C\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;\"\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 PETA monomer in a dry and low temperature (4°C) 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:\/\/advanced.onlinelibrary.wiley.com\/doi\/full\/10.1002\/adfm.202201191\"\u003eS.
