Poly(dopamine) (PDA) was investigated as a primer to enhance adhesion in flexible optoelectronic devices using the conducting polymer PEDOT:PSS. PDA improved wettability on polypropylene (PP) but reduced it on poly(ethylene terephthalate) (PET). However, PDA enhanced the quality and adhesion of pristine PEDOT:PSS and PEDOT:PSS/Tween 80 films on glass, PP, and PET. Crucially, it did not negatively affect sheet resistance of PEDOT:PSS/Tween 80 films, establishing its suitability as a primer for flexible substrates. This research addresses a key challenge in utilizing PEDOT:PSS in flexible optoelectronics, enhancing its performance on various substrates.
