Description

Polyaniline is a high-performance intrinsically conductive polymer (ICP) known for its excellent electrical properties and environmental stability. Its unique ability to switch between conductive and insulating states makes it a critical material for advanced electronic and anti-corrosion applications. This product is essential for R&D and manufacturing in sectors such as electronics, energy storage, and functional coatings, where reliable conductivity and processability are paramount.

Application

• Conductive Coatings & Inks: Used in printed electronics, anti-static coatings, and electromagnetic interference (EMI) shielding.
• Corrosion Protection: Acts as a primer or additive in paints and coatings for metals (e.g., steel, aluminum) to provide anodic protection.
• Energy Storage Devices: A key component in the electrodes of supercapacitors and rechargeable batteries due to its pseudocapacitive behavior.
• Chemical Sensors: Employed as a sensitive layer in gas (NH₃, NO₂) and biosensors because its conductivity changes upon analyte exposure.
• Electrochromic Devices: Used in smart windows and displays that change color or opacity with an applied voltage.
• Organic Electronics: Serves as a hole-transport layer or active material in organic light-emitting diodes (OLEDs) and field-effect transistors (OFETs).
• Textile & Fiber Engineering: Imparts conductivity to fabrics for smart textiles and wearable technology.

Quality Control

Our Polyaniline is produced under controlled conditions to ensure batch-to-batch consistency and performance. Quality is verified through a suite of analytical tests including conductivity measurement, spectroscopic identification, and thermal analysis. A Certificate of Analysis (COA) detailing purity, doping level, and key physical properties 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, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent aggregation and maintain its electrical properties.
