Description

Polyaniline (Emeraldine Salt) Short Chain is a conductive polymer in its doped, electrically active form, characterized by a shorter polymer chain length for enhanced processability. This material matters for its unique combination of electrical conductivity, environmental stability, and tunable properties, making it a cornerstone for advanced functional materials. It is critically needed by R&D teams and manufacturers in the electronics, sensors, and advanced coatings industries seeking innovative conductive solutions.

Application

• Conductive Inks and Coatings: Used in printed electronics, anti-static coatings, and electromagnetic interference (EMI) shielding applications.
• Chemical Sensors: Acts as an active sensing layer for detecting gases (e.g., ammonia, hydrogen sulfide) and vapors due to its conductivity changes upon analyte interaction.
• Corrosion Protection: Formulated into smart coatings for metals (e.g., steel, aluminum) where it provides anodic protection and barrier properties.
• Energy Storage Devices: Employed as an active material or additive in supercapacitors and battery electrodes to enhance charge storage capacity.
• Electrochromic Devices: Used in windows and displays that change color or opacity with an applied electrical voltage.
• Antistatic Packaging: Incorporated into polymers and fabrics to dissipate static charge, protecting sensitive electronic components.

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 (TGA). A Certificate of Analysis (COA) detailing purity, conductivity, and other critical parameters is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This material is hygroscopic (moisture-sensitive) and easily oxidized; for long-term storage, consider keeping under an inert atmosphere (e.g., nitrogen or argon) in a desiccated environment.
