The importance of water cannot be overstated. It is the most important natural resource for our survival and development. The development of suitable materials for efficient water purification will provide a critical contribution for sustainable water use. In this context, a gel–emulsion‐templated synthesis of a polymeric aerogel has been developed for water treatment. Owing to its hydrophobic nature, the aerogel shows high sorption (nearly 20 times its weight) for organic liquids, such as toluene, phenol, and nitrobenzene, and can be used to remove them from water. The aerogel shows low thermal conductivity (0.032 W m−1 K−1) and excellent light absorption efficiency (>92 %) after carbonization, which provides the possibility for the construction of an interfacial solar vapor generation system. The as‐prepared materials are used to develop a two‐step approach to remove both organic and inorganic contaminants (salts) from water. Importantly, the aerogel shows excellent reusability and high efficiency both for oil sorption and for solar vapor generation. Moreover, the low cost and easy scale‐up of the preparation process lay a solid foundation for practical application. It is anticipated that the prepared aerogels would contribute not only to water purification but also to other related areas.

“…Because of favorable internal structures, porous materials have shown bright future in many areas. [25][26][27] In addition, preparation of some porous materials can be easily scaled up, which would greatly facilitate their potential applications. [22][23][24] In our previous work, we have synthesized a series of low-density porous materials with outstanding absorbing/ adsorbing performance for VOCs owing to their hydrophobicity, large surface area, and interconnected network channels.…”

Innovative design and fabrication of fluorescent films are key steps in the development of film‐based fluorescent sensors, where both sensing unit and substrate are crucial to the performance of the films. To improve sensing performance via increasing mass transfer, hierarchical porous particles are chosen as substrate. NBDCOOH is adopted as a representative sensing fluorophore, and is immobilized onto the particles via physical adsorption. Dispersing the fluorescent particles into a mixture of ethanol and glycerol results in a fluorescent ink. It is demonstrated that the fluorescence of the film obtained from this particle‐based ink is more than 45 times stronger than that from pure NBDCOOH solution. In addition, the particle‐based film shows much improved photochemical stability and enhanced sensing performance. Owing to its printability, it can be used to generate complex patterns, which can be used for advanced information encryption.

“…Besides the above mentioned separation applications, polyHIPEs have been applied for separation of particulate matters [76, 156], Enterovirus 71 [157], microalgae [100], anions [99, 146, 158, 159], and adsorption of water and other solvents [70, 160–162]. Triplicate injections of 5 and 10 nm gold particles injected onto a STY/DVB polyHIPE column produced an average difference in retention time of 135 s, and triplicate injections of 52 and 155 nm dysprosium‐doped PS latex particles produced a difference in retention time of 8 s, indicating the potential of polyHIPEs for separation of nanoparticles [76].…”

Polymerized high internal phase emulsions as highly porous adsorption materials have received increasing attention and wide applications in separation science in recent years due to their remarkable merits such as highly interconnected porosity, high permeability, good thermal and chemical stability, and tailorable chemistry. In this review, we attempt to introduce some strategies to utilize polymerized high internal phase emulsions for separation science, and highlight the recent advances made in the applications of polymerized high internal phase emulsions for diverse separation of small organic molecules, carbon dioxide, metal ions, proteins, and other interesting targets. Potential challenges and future perspectives for polymerized high internal phase emulsion research in the field of separation science are also speculated at the end of this review.
