“…This work provides a new perspective for catalyst design using the template method. In a different approach, Zhan et al 115 employed diverse precursors. They used a porous PAN fiber felt as a precursor framework, assembled with silver-decorated Bi 2 O 3 @3D MXene Schottky heterojunction as assembling material, and hydrophilic TA as a binder to prepare a highly permeable, fouling-resistant composite membrane (Fig.…”

“…In recent years, the two-dimensional (2D) lamellar nanomaterial-based composite membranes (graphene oxide, MXene nanosheets, g-C 3 N 4 , etc.) have been widely applied for the O/W separation due to their tunable water channel, high filtration precision, easy functionalization, etc. − Typically, inspired by the wetting behavior of marine organism such as mussel and fish, various superhydrophilic 2D lamellar composite membranes are of interest, which can efficiently mitigate oil fouling and allow water permeation. , However, the physically stacked and compacted functional layer of graphene oxide greatly limit the permeation of composite membranes. , In addition, though the graphene oxide and MXene nanosheets possess the natural hydrophilicity, they easily cause the swelling problem under water environment, which destroys the integrity of the membrane. , Therefore, the preparation of high-performance 2D lamellar composite membranes for oily sewage treatment is challenging …”

The synergistic treatment of oily wastewater containing organic hazards and emulsified oils remains a big challenge for membrane separation technology. Herein, the photocatalytic membrane, which combined the physical barrier and catalytic oxidation-driven degradation functionality, was fabricated via anchoring a nanoflower-branched CoAl-LDH@ PANI Z-scheme heterojunction onto a porous polyacrylonitrile mat and using tannic acid as an adhesive. The assembly of such a Z-scheme heterojunction offered the superior photocatalytic degradation performance of soluble dyes and tetracycline (up to 94.3%) to the membrane with the improved photocatalytic activity of 2.33 times compared with the CoAl-LDH@pPAN membrane. Quenching experiments suggested that the • O 2 − was the most reactive oxygen species in the catalytic reaction system of the composite membrane. The greatly enhanced photocatalytic activity was attributed to the effective inhibition of photogenerated hole− electron combination using PANI as a carrier, with charge transferring from LDH to PANI. The possible photocatalytic degradation mechanism was proposed based on VB-XPS, electron spin resonance spectroscopy, and DRS technologies, which was confirmed by density functional theory calculation. Meanwhile, benefiting from the superhydrophilic/oleophobic feature and low oil adhesion, the membrane exhibited high permeability for isooctane emulsion (3990.39 L•m −2 •h −1 ), high structure stability, and satisfactory cycling performance. This work provided a strategy to develop superwetting and photocatalytic composite membranes for treating complex multicomponent pollutants in the chemical industry.

Biomimetic synthesis provides potential guidance for the synthesis of bio‐nanomaterials by mimicking the structure, properties and functions of natural materials. Behavioral studies of biological surfaces with specific micro/nano structures are performed to explore the interactions of various molecules or organisms with biological surfaces. These explorations provide valuable inspiration for the development of biomimetic surfaces with similar effects. This work reviews some conventional preparation methods and functional modulation strategies for biomimetic interfaces. It aims to elucidate the important role of biomimetic interfaces with antifouling and low‐pollution properties that can replace non‐environmentally friendly coatings. Thus, biomimetic antifouling interfaces can be better applied in the field of marine antifouling and antimicrobial. In this review, the commonly used fabrication methods for biomimetic interfaces as well as some practical strategies for functional modulation is present in detail. These methods and strategies modify the physical structure and chemical properties of the biomimetic interfaces, thus improving the wettability, adsorption, drag reduction, etc. that they exhibit. In addition, practical applications are presented of various biomimetic interfaces for antifouling and look ahead to potential biomedical applications. By continuously discovering functional surfaces with biomimetic properties and studying their microstructure and macroscopic properties, more biomimetic interfaces will be developed.
