Stretchable PEDOT conductive ink is a functional material that combines the conductivity of PEDOT with the stretchability of elastomers, and can be used to fabricate stretchable electronic devices (such as flexible circuits, wearable sensors, electronic skin, etc.). The stretchable PEDOT conductive ink provided by Xianfeng Nano has solution processability and can be used to prepare patterned circuits through processes such as screen printing, inkjet printing, and blade coating. It is compatible with various substrates and can be directly printed on flexible substrates (such as PET and PI films), elastomers (PDMS, Ecoflex), or fabrics (cotton, polyester). It has a high tolerance for substrate surface roughness and does not require complex pretreatment.
