{"product_id":"cgpepvdftrfe","title":"PVDF-TrFE {(poly(vinylidene fluoride-trifluoroethylene)} as Gel Polymer Electrolyte (GPE), 100 g\/bottle, CGPEPVDFTrFE","description":"\u003cp\u003eUsing PVDF-TrFE (poly(vinylidene fluoride-trifluoroethylene)) as the host matrix for a gel polymer electrolyte (GPE) is a highly effective strategy for next-generation batteries, particularly when dealing with aggressive chemistries like high-voltage lithium-ion, sodium-ion, or solid-state lithium-metal cells. Compared to standard PVDF or PVDF-HFP, the introduction of the TrFE term alters the polymer physics in ways that directly translate to better electrochemical performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEnhanced Ferroelectric Polar Phase (β-phase)\u003c\/strong\u003e: Standard PVDF naturally crystallizes into the non-polar a-phase, requiring mechanical stretching or specific quenching to achieve the highly polar β-phase. The strong dipole moment of the C-F bonds in the β-phase increases the dielectric constant of the polymer matrix. This high dielectric constant heavily promotes the dissociation of metal salts (e.g., LiTFSI, NaFSI, or NaClO4), leading to a higher concentration of free mobile ions and reducing ion-pairing.\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: 256.6px;\" 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\u003eCGPEPVDFTrFE (C-GPE-PVDFTrFE)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 55.2px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 55.2px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 55.2px;\"\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 src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CGPEPVDFTrFE_chemical_structure_100x100.jpg?v=1783224936\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 33.8px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 33.8px;\"\u003e\u003cem\u003eAverage Molecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 33.8px;\"\u003e\n\u003cp\u003e\u003cspan\u003eMw = ~450000, 100 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 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\/S0378775313011580\"\u003e\u003cspan\u003eC.
