“…Another challenge is the separation of highly viscous oil, driving various viscosity reduction strategies, such as photothermal effect [15,21], joule-heating [22,23], magneto-heating [24]. Fortunately, Janus composites offer the advantage of coupling multi-functionalities [3,25]. It is possible to achieve higher separation e ciency for minisize emulsi ed viscous oils using difunctional Janus porous composites.…”

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.

Colloidal particle research has witnessed significant advancements in the past century, resulting in a plethora of studies, novel applications, and beneficial products. This review article presents a cost-effective and low-tech method for producing Janus elastomeric particles of varied geometries, including planar films, spherical particles, and cylindrical fibers, utilizing a single elastomeric material and easily accessible chemicals. Different surface textures are attained through strain application or solvent-induced swelling, featuring well-defined wavelengths ranging from sub-microns to millimeters and offering easy adjustability. Such versatility renders these particles potentially invaluable for medical applications, especially in bacterial adhesion studies. The coexistence of “young” regions (smooth, with a small surface area) and “old” regions (wrinkled, with a large surface area) within the same material opens up avenues for biomimetic materials endowed with additional functionalities; for example, a Janus micromanipulator where micro- or nano-sized objects are grasped and transported by an array of wrinkled particles, facilitating precise release at designated locations through wrinkle pattern adjustments. This article underscores the versatility and potential applications of Janus elastomeric particles while highlighting the intriguing prospects of biomimetic materials with controlled surface textures.
