{"product_id":"cssbepegda","title":"PEGDA {Poly(ethylene glycol) diacrylate} as Solid-State Battery Electrolyte, CSSBEPEGDA","description":"\u003cp\u003ePEGDA (Poly(ethylene glycol) diacrylate) is a foundational building block for crosslinked solid-state polymer electrolytes. While standard linear PEO suffers from high room-temperature crystallinity (which locks down ion transport) and poor mechanical stiffness when melted, PEGDA completely alters this landscape. By featuring reactive acrylate groups (-C(=O)CH=CH2) at both ends of a flexible polyether chain, PEGDA can be cured (via thermal initiators like AIBN or UV photo-initiators) to form a robust, three-dimensional crosslinked polymer network.\u003c\/p\u003e\n\u003cp\u003eThe crosslinking density and behavior of a PEGDA network are highly sensitive to the molecular weight (Mn) of the underlying PEG segment (typically ranging from Mn = 200 to 2000 g\/mol). (1) \u003cstrong\u003eSuppression of Crystallinity\u003c\/strong\u003e: The covalent crosslinks (the acrylate \"junction points\") act as structural anchors that mechanically prevent the long polyether chains from aligning into rigid crystalline domains. This keeps the matrix completely amorphous at room temperature, unlocking continuous ion-conducting pathways. (2) \u003cstrong\u003eSegmental Motion vs. Elastic Mesh\u003c\/strong\u003e: Cations (Li+ or Na+) coordinate with the ethereal oxygens (-C-O-C-) along the PEG loops. Ion transport is driven by the local flipping and twisting of these chains (segmental motion). (3) \u003cstrong\u003eThe Mn Trade-Off\u003c\/strong\u003e: \u003cem\u003eLow Mn (e.g., 200–400)\u003c\/em\u003e: Tightly packed crosslinks, exceptional mechanical shear modulus (great for stopping dendrites), but highly restricted chain mobility, leading to lower ionic conductivity. \u003cem\u003eHigh Mn (e.g., 1000–2000)\u003c\/em\u003e: Long, loose polyether loops with high segmental mobility (excellent conductivity), but a softer, gel-like mechanical structure.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 288.663px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 58.775px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 58.775px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 58.775px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSSBEPEGDA (C-SSBE-PEGDA)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 67.9125px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 67.9125px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 67.9125px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u003cbr\u003e26570-48-9\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 72.288px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 72.288px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 72.288px;\"\u003e\n\u003cp\u003e(C3H3O)(C2H4O)n(C3H3O2)\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\/CSSBEPEGDA_chmical_structure_100x100.jpg?v=1783151491\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 57.225px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 57.225px;\"\u003e\u003cem\u003eAverage Molecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 57.225px;\"\u003e\n\u003cp\u003e\u003cspan\u003e(1) Mw = 1000, liquid form, 100 mL\/bottle\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e(2) Mw= 2000, solid powder form, 5 g\/bottle\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e(3) Mw= 5000, solid powder form, 5 g\/bottle\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e(4) Mw= 10000, solid powder form, 5 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 PEGDA 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\u003cspan\u003e\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0378775319300187\"\u003eF.
