Summary: A novel self-healing coating with photothermal and pH dual-responsive properties has been developed to protect carbon steel from corrosion. The coating utilizes stimuli-responsive microcapsules loaded into a shape memory epoxy coating. Under near-infrared light irradiation, the coating exhibits a photothermal effect and releases corrosion inhibitors. Additionally, the pH-responsive gatekeeper controls the release of inhibitors under acidic conditions. The coating demonstrates efficient self-healing performance, as evaluated by surface morphology analysis and electrochemical techniques.

Summary: This work introduces a novel nanocomposite coating with dual-action self-healing corrosion protection activated by the photothermal response of plasmonic titanium nitride nanoparticles, which efficiently suppresses the corrosion process at the exposed metal surface. The surface characterization and electrochemical measurement results proved that the nanocomposite coating exhibited optimal corrosion protection and excellent self-healing performance under NIR illumination within 30 seconds. This photo-controlled self-healing approach has the potential to design next-generation self-healing coatings with ultrafast response time and high healing efficiency.

Summary: Smart control of surface wettability, especially for superhydrophobic surfaces, has gained widespread attention. Shape memory superhydrophobic surfaces, based on the shape memory effect of shape memory polymers (SMPs), can intelligently control surface topographies and wettability, and have shown great potential for extensive applications. This review summarizes recent achievements and applications of shape memory superhydrophobic surfaces, introduces the research background, concepts, and significance, reveals the fundamental wetting theory and models, evaluation of shape memory effect, and mechanism. It also reviews recent advances in magnetic, photo, electrical, thermo, and chemical-induced shape memory superhydrophobic surfaces, and summarizes the major representative applications including wettability control, droplet manipulation, self-healing, and other smart applications. Finally, the future research directions and perspectives are discussed.

Summary: This study reports semi-crystalline polyurethanes with shape memory and self-healing effects, and investigates their structure, morphology, properties, self-healing mechanism, and shape memory mechanism. The results show that increasing the hard segment content promotes phase separation and reduces the crystallizability of the soft segments. The designed semi-crystalline polyurethanes with excellent biocompatibility are expected to be used as smart biomaterials in biomedical devices.

Summary: Liquid crystal elastomers (LCEs) are versatile polymer materials used in various applications, but the contradiction between reprogrammability and stable actuation performance remains a challenge. Introducing photoactivated dynamic covalent bonds (DCBs) into thermotropic LCEs can help address this issue. This study utilizes allyl selenide chemistry to achieve multiple network reconfigurations of LCEs under visible light conditions (405-450nm). The mild stimulation conditions and sustainable dynamic exchange capability offer great potential for the application and design of covalently adaptable LCEs.
