Organic Conductive Materials

Organic Conductive Polymer: VERAZOL™ WED Series
High Conductivity Grade: WED-SM

High conductivity grade WED-SM is a polymeric material fabricated by doped PEDOT (poly 3,4-ethylenedioxythiophene) with PSS (polystyrene sulfonate) and PTS (para-toluenesulfonic acid).

Structure

Features

  • High-purity product created by removing ionic impurities by our unique refining method
  • Realizes antistatic properties by adding only a small amount
  • Can be adapted to various printing methods by mixing with various types of binders
  • Provides highly transparent and low-haze coatings by mixing with various types of binders
→A wide range of designs from 10^3～9Ω/□ is available by changing the binder compounding ratio
