“…However, with the rapid development of modern technology, the monotonous superhydrophobicity has been unable to meet new requirements in some rising fields . Accordingly, the attempts to fabricate flexible superhydrophobic materials with at least one kind of function except water repellency have emerged in recent few years, and further widened the application fields in wearable sensing electronics, highly effective catalytic electrodes, controllable photothermal manipulation, and other cutting across areas …”

Functional superhydrophobic materials with shape memory and electrical conductivity play important roles in a wide variety of growing fields. Herein, a robust 3D porous superhydrophobic composite (PSC) with multiwalled carbon nanotube/poly(ethylene-co-vinyl acetate) (CNT/EVA) as its skeleton is proposed for recoverable shape reconfiguration and underwater vibration detection. Thanks to the capillary wicking of the interconnected porous structure and ethanol plasticization of the skeleton, this PSC achieves fast shape reconfiguration (<20 s) and recovery (<20 s), high shape fixity (>98%) and recovery ratio (>90%), and excellent shape-memory repeatability (>10 times) even at 80% compressive strain. Additionally, induced by the wave-sensitive air layer trapped on the superhydrophobic surface, the flexible CNT/EVA skeleton endures compressed/stretched deformation. Thus, the conductive PSC sensor presents high sensitivity in monitoring tiny underwater vibrations generated by stirring, objects falling, a ruler sliding, ultrasonic ation, and human activities. The findings conceivably stand out as a new methodology for the fabrication of functional superhydrophobic materials for innovative and broad applications.

Remarkable progress has been made in surface icephobicity in the recent years. The mainstream standpoint of the reported antiicing surfaces yet only considers the ice-substrate interface and its adjacent regions being of static nature. In reality, the local structures and the overall properties of ice-substrate interfaces evolve with time, temperature and various external stimuli. Understanding the dynamic properties of the icing interface is crucial for shedding new light on the design of new anti-icing surfaces to meet challenges of harsh conditions including extremely low temperature and/or long working time. This article surveys the state-of-the-art anti-icing surfaces and dissects their dynamic changes of the chemical/physical states at icing interface. According to the focused critical ice-substrate contacting locations, namely the most important ice-substrate interface and the adjacent regions in the substrate and in the ice, the available anti-icing surfaces are for the first time re-assessed by taking the dynamic evolution into account. Subsequently, the recent works in the preparation of dynamic anti-icing surfaces (DAIS) that consider time-evolving properties, with their potentials in practical applications, and the challenges confronted are summarized and discussed, aiming for providing a thorough review of the promising concept of DAIS for guiding the future icephobic materials designs.

Solar energy is an abundant clean and renewable energy source that has found wide uses in many energy‐intensive applications. It is normally transformed into other forms for certain applications, and light‐to‐heat conversion is one of the most common and efficient ways to utilize solar power. Previous reviews mostly focus on the solar‐driven evaporation for desalination, but few mention other applications in which the photothermal materials play a vital role. Herein, a Review regarding the sustainable uses of photothermal devices beyond desalination is presented. The recent developments of photothermal materials and progress on their applications in wastewater treatment, oil‐spill cleanup, moisture capture, energy harvesting during evaporation, sterilization, deicing, etc. are summarized. Herein, the working principles as well as property requirements in these applications are discussed and also the challenges with opportunities in future research are presented.
