Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.
