Description

Polyaniline (Emeraldine Salt) Long Chain is a conductive polymer in its doped, electrically active form, characterized by its extended polymer backbone. This material matters for its unique combination of processability, environmental stability, and tunable electrical conductivity, which is essential for advanced electronic applications. It is needed by industries focused on developing antistatic coatings, corrosion-inhibiting paints, electromagnetic interference (EMI) shielding, and sensitive chemical sensors.

Application

• Formulation of corrosion-inhibiting primers and paints for metals, particularly for aerospace and marine environments.
• Key component in conductive inks and adhesives used in printed electronics and flexible circuits.
• Manufacture of EMI/RFI shielding materials for electronic enclosures and composite materials.
• Fabrication of chemical and gas sensors due to its responsive conductivity to various analytes.
• Development of antistatic coatings for plastics, textiles, and packaging films.
• Research and development of organic electrodes for batteries and supercapacitors.
• Use as a functional additive in composite materials to impart electrical conductivity.

Quality Control

Our Polyaniline (Emeraldine Salt) is produced under controlled conditions to ensure batch-to-batch consistency. Quality is verified through a suite of analytical techniques including FT-IR for structural confirmation, conductivity measurements, and thermal analysis. A Certificate of Analysis (COA) detailing key parameters such as conductivity, doping level, and solubility is provided with each shipment to ensure compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C) under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and degradation. Keep away from strong acids and incompatible materials. The container must be kept tightly sealed due to the material's sensitivity to moisture.
