Special Issue Information

Dear Colleagues,

With the rapid development of the Internet of Things and wearable technology, smart materials have attracted significant attention due to their special ability to convert various signals such as force, heat, sound, light, and magnetism into electrical signals. Among them, polymer-based smart materials exhibit significant advantages due to their unique structural flexibility and stretchability. However, compared to traditional inorganic materials, polymer-based smart materials continue to exhibit deficiencies in their performance parameters, multifunctionality, and integration. Moreover, scenarios involving contact with the human body demand higher requirements regarding the biocompatibility and environmental friendliness of polymer-based smart materials. Therefore, this Special Issue focuses on novel polymer-based smart materials and their applications, and welcomes the submission of high-quality research papers that present innovative preparation and processing methods and application scenarios. We also welcome the submission of review articles.

The supported RuO2 catalysts are known for their synergistic and interfacial effects, which significantly enhance both catalytic activity and stability. However, polymer-supported RuO2 catalysts have received limited attention due to challenges associated with poor conductivity. In this study, we successfully synthesized the RuO2-polytetrafluoroethylene (PTFE) catalyst via a facile annealing process. The optimized nucleation and growth strategies enable the formation of RuO2 particles (~13.4 nm) encapsulating PTFE, establishing a conductive network that effectively addresses the conductivity issue. Additionally, PTFE induces the generation of oxygen vacancies and the formation of stable RuO2/PTFE interfaces, which further enhance the acidic OER activity and the stability of RuO2. As a result, the RuO2-PTFE catalyst exhibits a low overpotential of 219 mV at 10 mA cm⁻2 in the three-electrode system, and the voltage of the RuO2-PTFE||commercial Pt/C system can keep 1.50 V for 800 h at 10 mA cm−2. This work underscores the versatility of PTFE as a substrate for fine-tuning the catalyst morphology, the crystal defect, and the stable interface outerwear. This work not only broadens the application scope of PTFE in catalyst synthesis but also provides a novel approach to the design of high-performance metallic oxide catalysts with tailored oxygen vacancy concentration and stable polymer outerwear.

The use of organic semiconductors in electronic devices, including transistors, sensors, and memories, unlocks innovative possibilities such as streamlined fabrication processes, enhanced mechanical flexibility, and potential new applications. Nevertheless, the increasing technical demand for patterning organic semiconductors requires greater integration and functional implementation. This paper overviews recent efforts to pattern organic semiconductors compatible with electronic devices. The review categorizes the contributions of organic semiconductor patterning approaches, such as surface-grafting polymers, capillary force lithography, wettability, evaporation, and diffusion in organic semiconductor-based transistors and sensors, offering a timely perspective on unconventional approaches to enable the patterning of organic semiconductors with a strong focus on the advantages of organic semiconductor utilization. In addition, this review explores the opportunities and challenges of organic semiconductor-based integration, emphasizing the issues related to patterning and interconnection. Full article
