Biodegradable PEDOT:PSS/Clay Composites for Multifunctional Green‐Electronic Materials
AI summary Read the abstract
Researchers developed biodegradable PEDOT:PSS/montmorillonite clay composites with nacre-inspired layered nanostructures that are degradable by superworm larvae while maintaining multifunctional electronic properties. The work demonstrates a path toward reducing both electronic waste and microplastic pollution from conventional conductive polymer materials.
Abstract Plastics are now causing challenging environmental issues, especially electronic waste (E‐waste) and microplastics. While no single solution exists to address all these complex problems, superworms’ ingestion behavior toward plastics provides an innovative way to reduce plastic pollutions. Here, it is demonstrated that poly(3,4‐ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS)/montmorillonite (MMT) composites are biodegradable with versatile multifunctionalities originating from natural nacre‐inspired layered nanostructures. While their physical performances are modulated interdependently, eco‐biodegradability of the MMT/PEDOT:PSS composites are confirmed by the superworm's ingestion behaviors and their chemical changes after digestion. The electrically conductive composites with PEDOT:PSS also exhibit excellent mechanical properties, thermal stability, flame retardancy, long‐term water stability, flexibility, and electrochemical properties. Combined with these inherent multifaceted properties, the eco‐biodegradable features of the MMT/PEDOT:PSS composites open a new direction to use electronic materials for emerging eco‐friendly applications, including green‐electronics, bioelectronics, and edible‐electronics.
