{"product_id":"cfbhspedoti","title":"Highly Stretchable PEDOT Ink for Flexible Bioelectronics, 100 g\/bottle, CFBHSPEDOTI","description":"\u003cp\u003ePristine PEDOT:PSS films are brittle, with an elastic fracture strain typically below 5% and a high Young’s modulus (E \u0026gt;1–2 GPa). To bridge the mechanical mismatch with dynamic biological tissues (E ~ 1 kPa–100 kPa, strains \u0026gt;20–50%), stretchable PEDOT inks combine molecular plasticization, soft-matrix phase separation, and rheology tailoring for direct-write printing, inkjet, or screen printing.\u003c\/p\u003e\n\u003cp\u003eAchieving stretchability without sacrificing electronic conductivity relies on disrupting rigid, ionic PEDOT:PSS grain boundaries: (1) \u003cstrong\u003eNon-Ionic Plasticizers \u0026amp; Surfactants\u003c\/strong\u003e: Compounds: Triton X-100, Zonyl, Dynol, Sorbitol, PEG\/PEO oligomers. Screen the strong electrostatic crosslinking between PEDOT+ and PSS-, lowering the glass transition temperature (Tg) and enabling polymer chain slipping under tensile strain. (2) \u003cstrong\u003eIonic Liquid (IL) \/ Deep Eutectic Softening\u003c\/strong\u003e: Compounds: 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMIM][TFSI]), [BMIM][OTf], or choline chloride\/urea systems. Induces secondary doping while acting as an non-volatile liquid phase within the matrix, providing stretchability up to 100% with minimal resistance drift. (3) \u003cstrong\u003eElastomeric\/Hydrogel Blending \u0026amp; Semi-IPNs\u003c\/strong\u003e: Compounds: Waterborne polyurethane (WPU), polydimethylsiloxane (PDMS) emulsions, poly(acrylic acid) (PAA), or polyacrylamide (PAAm). Forms a bicontinuous, semi-interpenetrating polymer network (semi-IPN) where the elastomer dissipates mechanical energy under elongation while the PEDOT fibrillar mesh preserves the electrical pathway.\u003c\/p\u003e\n\u003cp\u003eThe key requirements for PEDOT applied in bioelectronic interface are: (1) \u003cstrong\u003eElectrochemical Impedance at the Bio-Interface\u003c\/strong\u003e: Conductive PEDOT networks must retain low interfacial charge transfer impedance even when strained, ensuring high signal-to-noise ratio (SNR) for biopotential sensing (EMG, ECG, single-unit neural spikes). (2) \u003cstrong\u003eCytotoxicity \u0026amp; Biocompatibility\u003c\/strong\u003e: Many high-performance secondary dopants and surfactants (e.g., concentrated fluoro-containing ionic liquids, harsh crosslinkers) are cytotoxic. Formulations intended for chronic implants or epidermal patches must substitute these with biocompatible alternatives like choline-amino acid ionic liquids, hyaluronic acid, or functionalized bio-compatible crosslinkers (e.g., (3-glycidyloxypropyl)trimethoxysilane \/ GOPS at low wt%). (3) \u003cstrong\u003eElectromechanical Fatigue Resistance\u003c\/strong\u003e: Under cyclic physiological strain (e.g., cardiac beating ~10–20% or joint flexion up to 50%), microcracks can nucleate in the conductive phase. Utilizing self-healing motifs (hydrogen-bonded domains or dynamic disulfide linkages) helps recover baseline resistance across thousands of extension-relaxation cycles.\u003c\/p\u003e\n\u003ctable style=\"width: 100%;
