{"product_id":"cgpepvdftrfecfe","title":"PVDF-TrFE-CFE {Poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene)} as Gel Polymer Electrolyte (GPE), 50 g\/bottle, CGPEPVDFTrFECFE","description":"\u003cp\u003eComapared to binary PVDF-TrFE copolymer, the PVDF-TrFE-CFE (poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene)) terpolymer introduces a critical structural upgrade: the inclusion of a bulkier, highly polar term that transforms the material from a conventional ferroelectric into a relaxor ferroelectric. In gel polymer electrolytes (GPEs), this terpolymer configuration drastically optimizes both ion transport physics and interfacial mechanics.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRelaxation of Crystallity via \"Defect Engineering\"\u003c\/strong\u003e: The chlorofluoroethylene (CFE) monomer acts as a structural defect or \"add-on\" within the regular PVDF-TrFE chain. The CFE unit introduces a significantly larger chlorine (Cl) atom into the fluorinated backbone. This sterically disrupts the long-range coherent ferroelectric coupling of the all-trans (TTTT) β-phase, breaking it down into localized nano-domains (relaxor ferroelectric behavior). By destroying long-range crystalline ordering, the terpolymer exhibits a massive increase in the amorphous fraction at room temperature compared to PVDF-TrFE. This vastly increases the matrix’s electrolyte uptake capacity and accelerates liquid-like polymer segment mobility (Tg reduction), driving higher ionic conductivity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTailored Amorphous\/Crystalline Ratio\u003c\/strong\u003e:  While pure PVDF is highly crystalline (which restricts ionic motion), the bulkier TrFE monomer disrupts structural regularity, lowering the overall crystallinity. This leaves a well-balanced amorphous framework that easily uptakes and traps liquid electrolytes\/plasticizers (like EC\/DEC, ionic liquids, or fluoroethylene carbonate). The resulting gel provides a continuous pathway for rapid liquid-like ionic diffusion while maintaining a robust, solid-like macroscopic structure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh Electrochemical \u0026amp; Interfacial Stability\u003c\/strong\u003e: The heavy fluorination of the PVDF-TrFE backbone gives it exceptional resistance to oxidative decomposition at high operating potentials (often stable up to 4.5V–4.8V vs. Li\/Li+). Additionally, the robust polymer network prevents the continuous migration of liquid solvents to the reactive metal anode, suppressing runaway Solid Electrolyte Interphase (SEI) growth and dendrite formation.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 216.8px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCGPEPVDFTrFECFE (C-GPE-PVDFTrFECFE)\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\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 10px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u003cbr\u003e28960-88-5\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 132px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 132px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 132px;\"\u003e\n\u003cp\u003e(C4H3F5)n\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\/CGPEPVDFTrFECFE_chemical_structure_100x100.jpg?v=1783228291\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 39.2px;\"\u003e\u003cem\u003eAverage Molecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 39.2px;\"\u003e\n\u003cp\u003e\u003cspan\u003eMw = ~600000, 50 g\/bottle\u003c\/span\u003e\u003c\/p\u003e\n\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 PVDF-TrFE-CFE in a dry place (glovebox is preferred). \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:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S2352152X25023096\"\u003e\u003cspan\u003eZ.
