By absorbing ultraviolet radiation, HCPK undergoes rapid cleavage to generate active free radicals, initiating the prompt polymerization of acrylate and methacrylate network precursors directly within separator membranes and electrode assemblies.\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003eIts functional roles in GPEs synthesis are: (1) \u003cstrong\u003eRapid In Situ UV-Gelation in Sealed Cells\u003c\/strong\u003e: HCPK enables the rapid conversion of low-viscosity liquid electrolyte\/monomer precursors (such as PEGDA, TPGDA, HDDA, or HDDMA blended with carbonate solvents and lithium\/sodium salts) into dimensionally stable, crosslinked gel networks within seconds to minutes under UV exposure. (2) \u003cstrong\u003eElimination of Thermal Stress \u0026amp; Side Reactions\u003c\/strong\u003e: Replaces traditional thermal radical initiators (such as AIBN or BPO) with a clean, room-temperature light-triggered mechanism, avoiding thermal expansion mismatches between cell components and preventing premature thermal decomposition of volatile components. (3) \u003cstrong\u003eHigh Interfacial Uniformity\u003c\/strong\u003e: Because HCPK dissolves uniformly into the liquid electrolyte phase without micro-scale phase separation, free radicals are generated homogeneously across separator pores and electrode microstructures, establishing a uniform 3D polymer mesh with high ionic conductivity (\u0026gt;10^{-3} S\/cm).\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ctable style=\"width: 100%; height: 481.562px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSSGPEPIHCPK (C-SSGPE-PI-HCPK)\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: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e947-19-3\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 169.725px;\"\u003e\n\u003ctd style=\"width: 28.0702%; height: 169.725px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 169.725px;\"\u003e\n\u003cp\u003e\u003cspan\u003eHOC\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e10\u003c\/sub\u003e\u003cspan\u003eCOC\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e5\u003c\/sub\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CSSGPEPIHCPK_structure_160x160.jpg?v=1793482038\" 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: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eWhite Powder\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: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.5%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 36.6px;\"\u003e\n\u003ctd style=\"width: 28.0702%; height: 36.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 36.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e204.26 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: 28.0702%; height: 35.6px;\"\u003e\u003cem\u003eMelt Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e45–49 °C\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 71.2px;\"\u003e\n\u003ctd style=\"width: 28.0702%; height: 71.2px;\"\u003e\u003cem\u003eAbsorption Wavelength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; height: 71.2px;\"\u003e\n\u003cp\u003e\u003cspan\u003eMaximum Absorption Peak: ~333 nm (and ~330 nm)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSecondary Absorption Peaks: ~244–245 nm and ~280 nm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSpecifically the absorption peak is 246, 280, and 331 nm (in ethanol solution)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.0375px;\"\u003e\n\u003ctd style=\"width: 28.0702%; height: 26.0375px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.6374%; 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 HCPK powder in a dry place (2-8 °C).\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:\/\/pubs.acs.org\/aapmcd\/article\/4\/1\/158\/374649\"\u003e\u003cspan\u003eM.
