Polyaniline (emeraldine salt) short chain, grafted to lignin
Polyaniline (emeraldine salt) short chain, grafted to lignin (CAS: 313949-90-5) is a conductive polymer derived from aniline, functionalised with lignin. This emeraldine salt form exhibits significant electrical conductivity, typically in the range of 1-2 S/cm. It is supplied as a powder with a particle size of 2-3 μm and a pH of 1.95 in a 5% aqueous solution. Its applications span materials science, particularly in conductive coatings, inks, and electronics.
Conductive Additive
Utilised as an additive in polymer blends and liquid dispersions to impart conductivity. Applications include corrosion-resistant coatings, antistatic fabrics, and conductive packaging materials.
Electronic Materials
Suitable for use in conductive inks, adhesives, and printed circuit boards. Its properties make it valuable for organic and printed electronics, including OPV materials.
Shielding and Absorption
Employed for radar and microwave absorption purposes, as well as for electromagnetic interference (EMI) and radio frequency interference (RFI) shielding applications.
Sensors
Can be incorporated into sensor designs due to its conductive and responsive nature, enabling detection of various analytes.
