Water- and Organic Solvent-Soluble Conducting Polymer, SELFTRON®
SELFTRON® is an innovative, proprietary “self-doped” material developed by TOSOH. It exhibits excellent conductivity without requiring any additives (secondary dopants) while offering outstanding water solubility and durability.
Self-Doped Conducting Polymer: Unlike conventional, general-purpose conducting polymers, it incorporates a water-soluble dopant into a pi-conjugated polymer, allowing it to be used as a uniform aqueous solution. It delivers exceptional coatability, storage stability, conductivity, and durability.
Versatile Processing & Forming Methods:
Coating: Forms a conductive film by applying the solution onto various substrates (such as films, glass, etc.) via spin coating or bar coating, followed by drying.
Printing: Fully compatible with a wide range of printing methods, including screen printing, gravure, and inkjet printing.
Impregnation: Seamlessly grants conductivity to fabrics, textiles, or porous materials through simple impregnation and subsequent drying.
Applications & Media
Key Applications: Highly anticipated as a next-generation organic electronics material for touch sensors, capacitors, organic solar cells, and flexible displays.

Frequently Asked Questions (FAQ)
A. Yes, it can be utilized stably under neutral conditions without any performance degradation.
A. Although it depends on the heat resistance of the substrate, the recommended drying temperature is 80 to 200°C. Ensuring that moisture or solvents are completely driven off is the key secret to minimizing surface resistance.
A. Yes. We can optimize parameters such as viscosity or wettability to perfectly match your specific process (bar coating, inkjet, screen printing, etc.) or propose a customized grade tailored to your required performance specifications.
