{"product_id":"cgpemhfba","title":"HFBA {2,2,3,4,4,4-Hexafluorobutyl acrylate} as Monomer for Gel Polymer Electrolytes (GPEs), 100 g\/bottle, CGPEMHFBA","description":"\u003cp\u003e2,2,3,4,4,4-Hexafluorobutyl acrylate (HFBA) is a specialized fluorinated acrylate monomer heavily researched for in situ polymerized gel polymer electrolytes (GPEs) in advanced high-energy-density batteries. Compared to unfluorinated acrylates (like methyl or ethyl acrylate) or standard ether-based matrices (like PEO or PEGDA), HFBA alters the polymer solvation structure and interfacial chemistry, making it ideal for high-voltage cathodes (such as ultra-high nickel NCM811 or NCM9451) and lithium\/sodium metal anodes.\u003c\/p\u003e\n\u003cp\u003eThe molecular structure of HFBA features a polymerizable acrylate head group attached to a heavily fluorinated tail: CH2=CH--COO-CH2-CF2-CH(CF3). The densely packed fluorine atoms (-CF2-) and (-CF3-) groups introduce specific characteristics to the gel matrix: The fluorine atoms pull electron density away from the acrylate backbone, drastically raising the monomer's oxidation potential and preventing premature degradation at high operational voltages. Fluorinated segments reduce the overall surface energy of the gel polymer, promoting uniform wetting on polyolefin separators and lithium metal surfaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Fluorine-Oxygen Co-Coordination Effect\u003c\/strong\u003e: In a typical unfluorinated polyacrylate or PEO matrix, metal cations (Li+ or Na+) coordinate strongly with the carbonyl (C=O) or ether (C-O-C) oxygens. This tight binding means the ions can only move when the polymer chains physically relax, limiting ionic conductivity. Poly(HFBA) alters this via a unique fluorine-oxygen co-coordination structure. The weak, localized interactions from the neighboring fluorine atoms balance out the oxygen coordination, allowing the metal ions to readily decouple from the polymer chain. This accelerates ion hopping independent of polymer segment relaxation, boosting the cation transference number. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIn Situ Formation of an Inorganic-Rich SEI\/CEI\u003c\/strong\u003e: During the initial electrochemical cycles, the fluorinated side-chains (-CF2-CF-CF3-) are highly sensitive to preferential decomposition at the electrode surfaces before the bulk organic liquid solvents can break down: \u003cstrong\u003e\u003cem\u003eAnode (SEI)\u003c\/em\u003e\u003c\/strong\u003e: It decomposes to form a dense, uniform, and highly elastic Lithium Fluoride (LiF) or Sodium Fluoride (NaF)-rich inorganic solid electrolyte interphase. This high-surface-energy inorganic layer effectively blocks electron tunnel effect, regulates ion flux, and suppresses dendrite growth. \u003cstrong\u003e\u003cem\u003eCathode (CEI)\u003c\/em\u003e\u003c\/strong\u003e: On aggressive, high-nickel cathodes (like NCM811 or NCM9451), it forms a highly stable Cathode Electrolyte Interphase (CEI) that mitigates transitional metal dissolution and oxygen evolution at cut-off voltages exceeding 4.5 V.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 268.65px;\" 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\u003eCGPEMHFBA (C-GPE-M-HFBA)\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\u003e54052-90-3\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 113.725px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 113.725px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 113.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eH\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\u003eCF\u003c\/span\u003e\u003csub\u003e2\u003c\/sub\u003e\u003cspan\u003eCH(F)CF\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CGPEMHFBA_chemical_structure_100x100.jpg?v=1783298075\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.0576%;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;98%\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\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 10px;\"\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003e236.11 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\u003e1.389 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 (liquid)\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 HFBA 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:\/\/advanced.onlinelibrary.wiley.com\/doi\/full\/10.1002\/adma.202403191\"\u003e\u003cspan\u003eJ.
