{"product_id":"cbpedotpssfdp","title":"PEDOT:PSS Freeze-Dried Powder for Bioelectronics, 175 mg\/bottle, CBPEDOTPSSFDP","description":"\u003cp\u003eFreeze-dried (lyophilized) PEDOT:PSS powder is a solid-state precursor format designed to overcome the strict processing and shelf-life limitations of commercial aqueous dispersions (e.g., Clevios™ PH1000). By dehydrating the core–shell colloidal micelles under vacuum, it provides a stable, highly concentrated, or solvent-adaptable raw material for bioelectronic inks, conductive hydrogels, and 3D neural scaffolds. \u003c\/p\u003e\n\u003cp\u003eStandard PEDOT:PSS is supplied as a dilute (1.0–1.3 wt%) aqueous suspension. Transforming it into a lyophilized powder addresses several formulation bottlenecks: (1) \u003cstrong\u003eSolvent Incompatibility\u003c\/strong\u003e: Bioelectronic substrates (e.g., biodegradable PLGA, silk fibroin, or porous PDMS) can degrade, swell unevenly, or resist wetting in pure water. Lyophilized powder can be reconstituted in polar organic solvents (DMSO, DMF, ethylene glycol, or fluorinated alcohols). (2) \u003cstrong\u003eHigh Solids Loading for Direct Writing\u003c\/strong\u003e: Formulating high-viscosity pastes or shear-thinning inks for extrusion printing requires solid contents of 5–15 wt%—unachievable by simple thermal evaporation without inducing irreversible macro-aggregation. (3) \u003cstrong\u003eHydrogel \u0026amp; Composite Loading\u003c\/strong\u003e: Dry powder enables direct dry-blending into hydrogel precursors (e.g., gelatin-methacryloyl\/GelMA, alginate, polyurethane) without diluting the gel precursor matrix or disrupting crosslinking stoichiometry. (4) \u003cstrong\u003eShelf-Life \u0026amp; Storage\u003c\/strong\u003e: Eliminates long-term microbial growth, hydrolysis of PSS sulfonate groups, and irreversible room-temperature sedimentation\/flocculation.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 173px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCBPEDOTPSSFDP (C-B-PEDOTPSSFDP)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 11px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 11px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 11px;\"\u003e\n\u003cp\u003e155090-83-8\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003eChemical Formula\/Structure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBEBPEDOTPSS_molecular_structure_160x160.png?v=1765953749\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003eColor\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003eDeep blue powder\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003eUse Note\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003eIt can be readily dispersed in water or some organic solvent (may need ultrasonication assistance) to prepare very high concentration PEDOT:PSS solution for special applications. \u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003eStorage Conditions\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003eDark, low temperature freeze, dry\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 19.6px;\"\u003e175 mg\/bottle (around 10 mL 1.9 g\/mL PEDOT:PSS ink)\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 PEDOT:PSS freeze-dried powder in a dry and cold place (glovebox with fridge is the best option). \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:\/\/iopscience.iop.org\/article\/10.1149\/2.0581504jes\/meta\"\u003eP.
