Summary: The shortage of water resources and water pollution have become global environmental problems. The challenge lies in improving the separation performance and flux of high-performance filtration membranes. In this study, gradient structure fibrous membranes were designed and prepared, which showed hydrophilic properties and excellent mechanical and water transmission properties. The as-prepared hydrophilic gradient membranes demonstrated durable oil-fouling repellency with a separation efficiency of approximately 99% for oil/water mixture and a flux of 10,278 +/- 1512 L m-2 h-1. This method provides a feasible solution for high filtration resistance of electrospinning nanofiber membranes and the preparation of low-cost and high-performance composite membranes and functional membranes.

Summary: Superwetting properties with multiple superlyphobic states have unique advantages in specific interfacial applications. However, there is currently a lack of systematic research on fine controlling superwetting surfaces. Controllable fabrication of superoleophobic surfaces from superhydrophilicity to superhydrophobicity in oil is still a challenge due to the harsh conditions involved.

Summary: The research shows that polyelectrolyte brush surfaces are more oil-repellent when submerged under water due to the ability of charged moieties on the polymer backbone to retain strong hydration shells. Measurements of interaction forces between polyelectrolyte brushes and oil droplets reveal that surfaces with repulsive electric double-layer forces are most oil-repellent, and once a stable hydration layer forms, the characteristics of the polymer brush do not affect the oil-repellent performance.

Summary: This research presents a novel strategy for constructing 3D honeycomb porous films on curved substrates using the breath figure technique and an azobenzene-containing copolymer. The shape of nanopores changes with the drying speed of solvents and polarization direction. These porous films can be used as substrates to load metal nanoparticles, resulting in nanocomposites. The porous films exhibit higher catalytic activity than nonporous films, and UV irradiation promotes the catalytic action. This study is of great importance for the preparation of potential catalysts.
