“…It is possible to achieve higher separation e ciency for minisize emulsi ed viscous oils using difunctional Janus porous composites. Janus porous composites are usually created through two approaches: asymmetric fabrication [10,[26][27][28] and asymmetric decoration [17,[29][30][31]. Emulsion-templated porous polymers have gained signi cant attention as mother porous materials, due to their controlled pore size, highly interconnected porous structure, and exible scaffold constitution [32][33][34][35].…”

Efficient separation of emulsified oil is urgently needed to repair the ecological environment, given the explosive development in modern industrial civilization. Herein, Janus porous composites were constructed using two different paraffin oil-in-dimethylsulfoxide (DMSO) gel emulsions. One of the gel emulsions contained graphene oxide (GO) within the DMSO phase, while the other continuous phase was dissolved with triarm hydroxyl-terminated poly(ε-caprolactone) (PCL-triol). To create Janus porous composites, the gel emulsions were overlaid and solidified with poly[(phenyl isocyanate)-co-formaldehyde] through step-growth polymerization. The resultant GO/PCL Janus porous composites exhibited an asymmetric double-layer structure with a tightly bonded interface. GO/PCL Janus porous composites displayed asymmetric surface wettability, functioning as a liquid diode, and enabling effective separation of oil-in-water (O/W) miniemulsion. The separation efficiency could be further improved under simulated solar irradiation, due to heat-induced viscosity reduction and phase separation caused by the photothermal conversion effect of the GO-based layer. These Janus porous composites demonstrated excellent performance in oil-water separation, making them an ideal candidate for such applications.

Lignocellulose‐mediated liquid metal (LM) composites, as emerging functional materials, show tremendous potential for a variety of applications. The abundant hydroxyl, carboxyl, and other polar groups in lignocellulose facilitate the formation of strong chemical bonds with LM surfaces, enhancing wettability and adhesion for improved interface compatibility. Beyond serving as a supportive matrix, lignocellulose can be tailored to optimize the microstructure of the composites, adapting them for diverse applications. This review comprehensively summarizes the fundamental principles and recent advancements in lignocellulose‐mediated LM composites, highlighting the advantages of lignocellulose in composite fabrication, including facile synthesis, versatile interactions, and inherent functionalities. Key modulation strategies for LMs and innovative synthesis methods for functionalized lignocellulose composites are discussed. Furthermore, the roles and structure–performance relationships of these composites in electromagnetic shielding, flexible sensors, and energy storage devices are systematically summarized. Finally, the obstacles and prospective advancements pertaining to lignocellulose‐mediated LM composites are thoroughly scrutinized and deliberated upon. This review is expected to provide basic guidance for researchers to boost the popularity of LMs in diverse applications and provide useful references for design strategies of state‐of‐the‐art LMs.

Silicon/carbon (Si/C) composites present great potential as anode materials for rechargeable batteries since the materials integrate the high specific capacity and the preferable cycling stability from Si and C components, respectively. Functional Si/C composites based on lignocellulose have attracted wide attention due to the advantages from lignocellulose, including sustainability property, flexible structural tunability, and diverse physicochemical functionality. Although the flourishing development of rechargeable batteries boosts the studies on lignocellulose‐derived Si/C materials with high electrochemical performance, the publications that comprehensively clarify the design and functionalization of these high‐profile materials are still scarce. Accordingly, this review first systematically summarizes the recent advances in the structural design of lignocellulose‐derived Si/C composites after a brief clarification about the Si selection sources based on self and extraneous sources. Afterward, the functionalization strategies, including nanosizing, porosification, and magnesiothermic reduction of Si material as well as heteroatom modification of C material, are specifically highlighted. Besides, the applications of lignocellulose‐derived Si/C‐based materials in rechargeable batteries are elaborated. Finally, this review discusses the challenges and prospects of the application of lignocellulose‐derived Si/C composites for energy storage and provides a nuanced viewpoint regarding this topic.
