{"product_id":"cspbtcpedoti","title":"Transparent \u0026 Conductive PEDOT Ink for Screen-Printed Bioelectronics, 100 g\/bottle, CSPBTCPEDOTI","description":"\u003cp\u003eConductive PEDOT screen-printing inks allow roll-to-roll and sheet-fed manufacturing of flexible, biocompatible electrodes for biosensors, electrophysiological monitors (ECG, EMG, EEG), and organic electrochemical transistors (OECTs). Because standard commercial dispersions are water-thin (~ 10–30 cP at 1.3 wt%), formulating an ink for screen printing requires engineering high solid loadings, thixotropic rheology, secondary doping, and substrate adhesion.\u003c\/p\u003e\n\u003cp\u003eScreen printing forces a viscous paste through an emulsion-patterned mesh (typically 150 to 350 mesh count) using a squeegee blade. A viable bioelectronic formulation must balance four core properties: (1) \u003cstrong\u003eThixotropic Rheology\u003c\/strong\u003e: High zero-shear viscosity to avoid sagging through mesh openings, sharp shear-thinning behavior under squeegee shear, and quick structural recovery to maintain edge resolution. (2) \u003cstrong\u003eOpen-Screen Time (Anti-Drying)\u003c\/strong\u003e: Pristine aqueous inks dry rapidly on the stencil, causing screen clogging. Formulations require low-volatility, high-boiling co-solvents (e.g., diethylene glycol, glycerol, DMSO). (3) \u003cstrong\u003eHigh Conductivity \u0026amp; Volumetric Capacitance\u003c\/strong\u003e: Printed bio-electrodes require sheet resistance Rs \u0026lt; 50–300 Ω\/sq and high capacitance to maintain low interfacial impedance with tissue at 1kHz. (4) \u003cstrong\u003eAqueous \u0026amp; Delamination Stability\u003c\/strong\u003e: Printed electrodes deployed in biological media or sweat will rapidly disintegrate if excess PSS- is not chemically crosslinked.\u003c\/p\u003e\n\u003cp\u003eRegarding the substrate interfacing \u0026amp; bioelectronic applications: (1) \u003cstrong\u003eEpidermal \u0026amp; Textile Dry Electrodes (ECG \/ EMG)\u003c\/strong\u003e: Printed directly onto flexible thermoplastic polyurethane (TPU) or woven synthetic fabrics. Formulations plasticized with PEG or polyurethane emulsions withstand repetitive skin deformation and wash cycles without cracking. (2) E\u003cstrong\u003enzymatic Biosensor Transducers\u003c\/strong\u003e: Serves as the conductive working and counter electrode tracks for screen-printed amperometric test strips (e.g., glucose, lactate, uric acid). The high volumetric capacitance of PEDOT enhances the active surface area for enzyme immobilization relative to planar noble metals. (3) \u003cstrong\u003eNeural \u0026amp; Organ Interfacing\u003c\/strong\u003e: When deposited onto thin Kapton (PI) or Parylene-C films, screen-printed PEDOT arrays provide low-impedance neural recording sites without requiring expensive cleanroom photolithography.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 318.776px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 32.9886%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.6904%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSPBTCPEDOTI (C-SFB-TCPEDOTI)\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: 32.9886%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.6904%; height: 35.6px;\"\u003e\n\u003cp\u003e126213-51-2\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 120.4px;\"\u003e\n\u003ctd style=\"width: 32.9886%; height: 120.4px;\"\u003e\u003cem\u003eChemical Formula\/Structure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.6904%; height: 120.4px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CFBHSPEDOTI_02_100x100.jpg?v=1788813831\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 91.288px;\"\u003e\n\u003ctd style=\"width: 32.9886%; height: 91.288px;\"\u003e\u003cem\u003ePEDOT Ink Types\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.6904%; height: 91.288px;\"\u003e\n\u003cp\u003e(1) Polyols-based PEDOT Screen-Printed Ink\u003c\/p\u003e\n\u003cp\u003e300 mesh for screen print, surface resistance: 400-600 Ω\/sq, transparency: 93%\u003c\/p\u003e\n\u003cp\u003e(2) Aqueous PEDOT Screen-Printed Ink\u003c\/p\u003e\n\u003cp\u003e300 mesh for screen print, surface resistance: ~350 Ω\/sq, transparency: 90%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.8875px;\"\u003e\n\u003ctd style=\"width: 32.9886%; height: 35.8875px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.6904%; height: 35.8875px;\"\u003e100 g\/bottle\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 transparent PEDOT dispersion 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\u003ca href=\"https:\/\/advanced.onlinelibrary.wiley.com\/doi\/full\/10.1002\/advs.202513487\"\u003e\u003cspan\u003eH.
