Among the various environmental problems, water pollution closely affects human life. Dyes like methylene blue (MB) from laboratories, pharmaceuticals, and textile industries contribute to water pollution with their toxicity, carcinogenicity, and non-biodegradability, posing risks to both humans and the ecosystem. Conventional water treatment filters, including activated carbon or polymer membranes, commonly possess pore structures. In this study, a porous S-doped polyimides (S-PI) film was prepared using thermally induced phase separation, and an adsorption filter was directly fabricated on the porous S-PI scaffolds via a laser scribing technique. The filter generated H2O2 under voltage, enabling the electrochemical decomposition of MB. We investigated the impact of porous structure, reaction time, pH, and the applied voltages on the adsorption capacity and degradation performance. This approach holds potential in providing solutions for removing emerging contaminants from wastewater.
