“…As can be seen from Figure 9C, the higher the content of ZIF‐67, the higher the adsorption and removal rate of Sudan I by the ZIF‐67/GE‐HIPE composite membrane, indicating that the adsorption and removal of Sudan I by the composite membrane is mainly due to the contribution of ZIF‐67. In addition, during the process of Sudan I removal, porous ZIF‐67/Gelatin membrane could attain adsorption equilibrium within 3.5 h, which was faster than that of a hydrophobically modified hydrogel 62 . This phenomenon can be ascribed to the penetrated pore structure of the composite film that renders organic molecular Sudan I with a faster diffusion speed 39 …”

The high internal phase emulsion (HIPE) template method is widely used to prepare porous functional materials because of its designable emulsion components and adjustable porosity. Herein, amphiphilic gelatin (GE) as the sole emulsion stabilizer, and no additional emulsifiers were added to prepare a stable GE‐HIPE membrane and its zeolitic imidazolate framework‐67 (ZIF‐67) hybrid composite membrane. The ZIF‐67/GE‐HIPE composite membrane has good lipophilicity by constructing dual micro‐nano structures by HIPE template and in situ growth of ZIF‐67. When ZIF‐67 was grown in situ, the water contact angle (CA) increased from 58.1 ± 2° for the GE membrane to 121 ± 1.9° for ZIF‐67/GE‐HIPE composite membranes. Besides, the minimum CA of organic solvent is 4.5 ± 0.7° (n‐hexane). The ZIF‐67/GE‐HIPE composite membranes exhibit good O/W emulsion separation properties and adsorption removal ability of organic pollutants. After 10 times of recycling emulsion separation, the emulsion separation capacity of the membrane was still greater than 99.4%. The lipophilic dye removal rate of the ZIF‐67/GE‐HIPE composite membrane was 2.37 times higher than that of GE‐HIPE, and the adsorption process conforms to the pseudo‐second‐order model. Thus, this work provides a strategy for the preparation of GE‐based hydrophobic modified membrane and also presents a typical treatment of adsorption‐separation of lipophilic substances.

“…The aggregation form of hydrogels is neither solid nor liquid but a special form between solid and liquid. Almost all hydrophilic polymers can be used to form hydrogels. − According to the different synthetic materials, they can be divided into natural polymer (including cellulose, chitosan, alginate, and gelatin) hydrogels − and chemically synthesized (including poly(vinyl alcohol), poly(acrylic acid), and poly(ethylene glycol)) hydrogels. − According to different cross-linking types, they are also sorted into physical cross-linking hydrogels, − chemical cross-linking hydrogels , and physical/chemical dual cross-linking hydrogels. − Due to their good biocompatibility, biodegradability, and flexibility, hydrogels are appropriate for applications in wound healing, − as drug carriers, , in tissue engineering, , as sensors, − actuators, − and wearable electronics, , in catalysis, in solar water purification, − as supercapacitors, , etc.…”

Due to the good reliability and long-term stability, self-healing hydrogels have emerged as promising soft materials for tissue engineering, smart wearable sensors, bioelectronics, and energy storage devices. The self-healing mechanism depends on reversible chemical or physical cross-linking interactions. Self-healing hydrogels with fascinating features (including mechanical performances, biocompatibility, conductivity, antibacterial ability, responsiveness, etc.) are being designed and developed according to the practical application requirements. In this review, the recent progress on self-healing hydrogels in their synthesis strategies and multiple applications is summarized. Their synthesis strategies involve reversible chemical or physical cross-linking processes or a combination of the two. Their recent applications include flexible strain sensors, supercapacitors, actuators, adhesives, wound healing, drug delivery, tumor treatment, 3D printing, etc. Finally, the current challenges, future development, and opportunities for self-healing hydrogels are discussed.

Conductive hydrogels have recently attracted extensive attention in the field of smart wearable electronics. Despite the current versatility of conductive hydrogels, the balance between mechanical properties (tensile properties, strength, and toughness) and electrical properties (electrical conductivity, sensitivity, and stability) still faces great challenges. Herein, a simplified method for constructing hydrophobic association hydrogels with excellent mechanical and electrical properties is proposed. The prepared conductive hydrogels exhibit high tensile properties (≈1224%), high linearity in the whole‐strain–range (R2 = 0.999), and a wide strain sensing range (2700%). The conductive hydrogel can realize more than 1000 cycles of sensing under 500% tensile strain. As an application demonstration, an underwater communication device is assembled in combination with polydimethylsiloxane/Triton X‐100 film coating, which successfully transmits underwater signals and provides warning of potential hazards. This study provides a new research method for developing underwater equipment with excellent mechanical properties and sensing properties.
