“…The PVDF/PDA/PEI/EPTAC membrane is believed to exhibit different rough states in air and in water. The polymer chains would shrink in air and stretch in water because of the solvation of the water, causing roughness changes in water (Figure j). The results of the EDS element analysis on the surface of M-1.5 are shown in Figures e–i.…”

Polyvinylidene fluoride (PVDF) membranes have been widely used as ultrafiltration and microfiltration membranes for water treatment due to their excellent chemical stability and mechanical strength. However, the low separation efficiency arising from the contamination and the poor reproducibility limit the development of current PVDF-based membranes. Inspired by the offensive and defensive characteristics of spines of a hedgehog, a spinous polycationic polymer, which is synthesized by the polymerization of dopamine (DA) and subsequent grafting of dendritic polyethylenimine (PEI) and 2,3-epoxypropyltrimonium chloride (EPTAC) molecules, is grafted on the surface of the PVDF membrane. The composite PVDF membrane with a stinging structure and superhydrophilic polycations enables long-term protection against bacteria (such as E. coli) and high oil− water separation efficiency, as well as strong antiemulsification ability. The permeation flux of pure water is up to 4777.1 L m −2 h −1 bar −1 and the oil−water separation efficiency is no less than 99.1%. More interestingly, the membrane still retained a good antifouling performance after being recycled through a remolding process. The facile fabrication strategy can be expanded to construct other separation membranes, enabling them to be next-generation separation membranes for high-efficiency water purification.

The water pollution problem caused by large-scale industrial activity is becoming increasingly serious, which not only poses a major threat to the ecosystem and human health but also seriously impedes the green and sustainable development of modern society. It is urgent to efficiently purify stubborn wastewater containing oils and other pollutants to eliminate their harm to human and environment. Therefore, it is desirable to develop multifunctional materials that can simultaneously remove oil and various pollutants or microorganisms by filtration or absorption methods to meet the practical demand for highly effective purification of wastewater with complex components. This paper summarizes the latest research progress on the "oil

Ice formation on a solid surface is a major challenge in industrial applications, it causes higher energy consumption and performance deterioration and may lead to catastrophic results. The preparation of anti‐icing surfaces to prohibit ice accumulation on a surface is crucial to reduce operational costs and to extend the surface's lifetime. The utilization of cryoprotectants to obtain anti‐icing surfaces is an effective method and is applicable in multiple fields. Antifreeze proteins (AFPs) are natural cryoprotectants to obtain anti‐icing surfaces, which have the ability to decrease the freezing point and to prevent ice‐crystal growth via thermal hysteresis (TH) and ice recrystallization inhibition (IRI). This study reports the molecular cloning, expression, and production of AFP protein from Escherichia coli (E. Coli). This wok also demonstrates the activity of coated AFP on aluminum surfaces. The expressed AFP is immobilized on aluminum surfaces treated by oxygen plasma. The coated AFP exhibits promising antifreeze activity with a high anti‐icing ability on aluminum surfaces in the size of evaporator fins (40 × 40 cm). The outcome of this study provides new insights into the biotechnological implementation of AFPs to various industrial applications for energy‐saving and higher performance.
