Manufacturing Quality Control of Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Solid Content | Gravimetric Analysis | Sample is dried to constant weight; solid content is calculated as mass percentage of residue relative to original sample mass. |
| pH | Potentiometric Titration | Hydrogen ion activity is measured using a calibrated pH electrode in aqueous dispersion. |
| Conductivity | Electrical Conductivity Measurement | Ionic conductivity of aqueous dispersion is measured using a calibrated conductivity cell and meter. |
| PEDOT:PSS Ratio | UV-Vis Spectroscopy | Relative absorbance at characteristic wavelengths (e.g., ~520 nm for PEDOT, ~220 nm for PSS) is used to estimate compositional ratio via calibration curves. |
| Residual Monomer (EDOT) | Gas Chromatography (GC) | EDOT monomer is extracted and quantified based on retention time and peak area against calibrated standards. |
| Residual Oxidant (FeCl3 or (NH4)2S2O8) | Redox Titration | Oxidizing agents are titrated with standardized reducing agent (e.g., sodium thiosulfate) using redox indicator or potentiometric endpoint detection. |
| Sulfur Content | ICP-OES | Total sulfur is determined after acid digestion and nebulization; emission intensity at characteristic S wavelength is compared to calibration standards. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-MS | Digestion followed by isotopic quantification using mass spectrometry with high sensitivity and multi-element capability. |
| Viscosity | Rotational Viscometry | Shear stress response to controlled rotational shear rate is measured to determine dynamic viscosity of aqueous dispersion. |
| Particle Size Distribution | Dynamic Light Scattering (DLS) | Brownian motion-induced fluctuations in scattered laser light intensity are analyzed to derive hydrodynamic diameter distribution. |
| Ash Content | Gravimetric Ashing | Sample is incinerated at 550 C; ash content is calculated as mass percentage of residual inorganic material. |
| Chloride Ion Content | Ion Chromatography (IC) | Chloride ions are separated on an anion-exchange column and detected via conductivity detection relative to calibration standards. |
