Polyaniline (emeraldine salt) long chain, grafted to lignin
Polyaniline (emeraldine salt) long chain, grafted to lignin (CAS: 335349-50-3) is a conductive polymer material. This formulation, featuring ligno-sulfonic acid and para-toluene sulfonic acid as dopants, offers enhanced properties. It is supplied as a powder with a particle size of 2-3 μm and exhibits a conductivity of 4-6 S/cm. Primary applications include use as an additive in corrosion-resistant coatings, antistatic materials, conductive inks, and for electromagnetic interference shielding.
Corrosion Resistant Coatings
Utilised as an additive in polymer blends and liquid dispersions to enhance the corrosion resistance of coatings for various substrates.
Antistatic Materials
Incorporated into fabrics, coatings, and packaging materials to provide antistatic properties, reducing electrostatic discharge.
Conductive Inks and Adhesives
Forms the basis for conductive inks and adhesives used in printed electronics and electronic assembly applications.
EMI/RFI Shielding
Effective in applications requiring electromagnetic interference (EMI) and radio-frequency interference (RFI) shielding due to its conductive nature.
Organic Photovoltaic (OPV) Materials
Serves as a component in organic photovoltaic devices, contributing to their functional layers, such as buffer layers.
