Conductive inks and coatings are key tools for creating flexible conductive pathways on insulating materials, with applications in chemical engineering, electronics and sensor technologies. An international research team has now introduced a sustainable one-pot synthesis, combining polypyrrole (PPy) as the conductive filler and carboxylated styrene-butadiene rubber (XSBR) as the flexible binder. Reading tip: Bio-based coatingsThe EC Tech Report “Bio-based Coatings” is a hand-picked compilation of all the key aspects concerning bio-based coatings, offering the latest technical developments. Thanks to its low cost, ease of preparation and scalability, the composite latex offers strong potential as a conductive ink and antistatic material in polymer applications, representing a sustainable alternative to conventional solvent-based systems.
