Zeolite is a commonly utilized filler in mixed matrix membranes (MMMs) to enhance the effectiveness of gas separation due to its molecular sieving properties with high separation coefficients. However, the compatibility and suitability between the zeolite and the polymer membrane are prerequisites for preparing homogeneous membranes and an essential factor affecting gas separation performance. Herein, we synthesized nucleus-crown-crown structures by surface modification of SOD zeolite and prepared MMMs by doping them into Polymers of Intrinsic Microporosity (PIM-1) for efficient gas separation. FTIR, XRD, SEM, and TGA characterized the fillers and the MMMs. The average particle size of the filler was estimated to be approximately 552.43 nm by SEM images. The surface-modified SOD zeolite facilitates the rapid permeation of specific gas molecules and enhances the dispersion of SOD zeolite in the PIM-1 membrane, thereby improving gas separation performance. Compared with pure PIM-1 membrane, the MMMs with a loading of 7 wt % exhibited CO 2 and H 2 permeabilities reaching up to 7000.0 and 3600.0 Barrer; their selectivities for CO 2 /N 2 and H 2 /N 2 were measured at 17.7 and 9.29, respectively. MMMs with the best fill ratios exceeded the 2008 Robeson upper limits. The methods for surface modification of SOD zeolites provide a new way for the application of SOD zeolite in the area of gas separation.

Interfacial floater possessing an open surface diversifies the functions of current systems in the field of solar evaporation, micro‐detector, multiphase catalysis, etc. However, most of the current floaters still face challenges such as the anti‐submersion, orientation adjusting, and multifunctional capabilities. Drawing inspiration from water striders and diving bell spiders, here a superhydrophobic cellular origami (SCO) is proposed with reliable stability, submerge resistance, switchable floatability, and multifunctional integration. The remarkable floating ability is achieved through the air storage ability of superhydrophobic air cells. SCO floats stably on the water surface and has a maximum load capacity that is 48% higher than the superhydrophobic sheet. Besides, SCO can resurface rapidly after complete submersion, even using titanium metal as substrate. To further enhance the universality of SCO, the Janus SCO with unbalanced structure can float with a specific orientation facing up and the origami structure is optimized to be switchable with hinge structure for adjustable buoyancy. To prove the concept in 3D structure, a cylindrical SCO is presented for cable locating on the water surface. This study presents an achievable strategy to extend superhydrophobic surfaces into anti‐sinking floaters, offering valuable insights into the development of multifunctional interface carriers.
