Summary
Hydrogels, as versatile soft materials, have gained significant attention due to their unique properties, such as high water content, biocompatibility, and tunable mechanical behavior.
They are widely applied in biomedical engineering, soft robotics, and wearable electronics. However, challenges remain in optimizing their synthesis, processing techniques, and mechanical performance for advanced applications. This Special Issue aims to explore cutting-edge research addressing these critical aspects to advance the field.
The aim and scope of the Special Issue shall be highlighted.
This Special Issue seeks high-quality contributions on innovative strategies for hydrogel design, fabrication, and characterization. We welcome studies focusing on:
① Novel synthetic approaches (e.g., dynamic crosslinking, 3D printing).
② Advanced processing techniques to enhance functionality.
③ Mechanical property modulation for specific applications.
Both experimental and theoretical studies are encouraged to foster interdisciplinary discussions.
Suggested themes.
