General description

Polyaniline (emeraldine salt) short chain, grafted to lignin (PANI-LIG) is an intrinsic conductive polymer with good electrical and optical properties. PANI is grafted with lignin to enhance the tensile strength and the bulk modulus of the polymer. It can be used for a variety of optoelectronic applications.

Application

Additive in polymer blends and liquid dispersions for corrosion resistant coatings; antistatic fabrics, coatings, and packaging; conductive inks and adhesives; printed circuit boards; radar and microwave absorption; EMI/RFI shielding; sensors.
PANI-LIG can be used in a variety of applications such as energy harvesting, dye sensitized solar cells, biosensors, and synthesis of ruthenium nanoparticles.

Features and Benefits

Inherently conductive polymer. Redox active up to a pH of 9.

Chem/Phys Resistance

Stable at 300 °C for 30 mins. Insoluble in most solvents. Dispersible over a wide pH range in water and polar, protic organic solvents including isopropanol, DMSO, DMF, and NMP.

Other Notes

Shake well before use.
