General description

• Helios’Ink H-SZ41029 semi conductive ink developed for the printed electronics is particularly well suited for flexible OLED and OPV.
• Helios’Ink H-SZ41029 semi conductive ink shows great performance on spin coating and slot die coating and is compatible with various flexible substrates (polyimide, PET, PET/ITO, etc.) but also Glass/ITO.

Features and Benefits

Product benefits:
• Easy deposition under atmospheric conditions (temperature and pressure).
• Good optical performances (visible light transmission >90%).
• Non CMR ink.
• Compatible with ITO layer and Ag NWs layer.
• Compatible with most flexible substrates.
• Low drying temperature making printing onto flexible substrates possible.
• Thin layers are obtained (20 nm) with low roughness (RMS = 3±1 nm).

Preparation Note

Typical processing guideline:
• Can be homogenized for 5 minutes in an ultrasonic bath in order to get rid of any aggregates.
• Drying conditions: Oven, IR oven, vacuum oven.
• Clean-up solution: Ethanol/Acetone.
