Description

Polypyrrole, Polymer-Supported, 20 Wt. % Dispersion In Water is a conductive polymer composite designed for ease of processing and integration. This aqueous dispersion offers a stable, ready-to-use formulation that combines the intrinsic electrical conductivity of polypyrrole with the mechanical and processing benefits of a polymer support matrix. It is a critical material for researchers and manufacturers in electronics, sensors, and advanced coatings who require a solution-processable conductive component without the handling challenges of powders.

Application

• Conductive Coatings and Inks: For creating anti-static surfaces, electromagnetic interference (EMI) shielding layers, and printed electronics on flexible substrates.
• Chemical and Biosensors: As an active sensing layer due to its conductivity changes upon exposure to specific analytes, gases, or vapors.
• Corrosion Protection: Formulation of smart anti-corrosion coatings for metals, where the conductive polymer can provide anodic protection.
• Energy Storage Devices: Used in the development of electrodes for supercapacitors and hybrid battery systems.
• Actuators and Artificial Muscles: Exploiting the volume change of polypyrrole during redox cycling for electromechanical applications.
• Antistatic Packaging: Incorporation into films and composites to dissipate static charge in sensitive electronic components.

Quality Control

Our conductive polymer dispersions are produced under strict quality control protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as solid content, particle size distribution, pH, and conductivity are rigorously tested. A Certificate of Analysis (COA) detailing these specifications is provided with each shipment to support your R&D and manufacturing requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at room temperature (15-25°C). Do not freeze. The dispersion should be gently agitated before use to ensure homogeneity. Keep away from strong oxidizing agents.
