Summary: A simple method of coaxial electrospinning was proposed to manufacture superhydrophobic membranes for ultrafast separation of water-in-oil emulsions. By designing asymmetric composite membranes with selective layers, the mass transfer resistance was reduced, resulting in high separation efficiency and permeance. The manufactured membrane showed strong promise in separation of water-in-oil emulsions, with a large size, continuous production, and potential for further enlargement.

Summary: Increased industrial oily effluent discharge poses a threat to the environment and human health, leading researchers to develop practical technologies for oil-water separation. Superhydrophobic surfaces have emerged as a popular solution for this purpose, and in this study, rockwool was modified with a superhydrophobic coating to exhibit excellent water-repellent and oil-absorbent properties. The modified rockwool demonstrated a water contact angle of over 150 degrees and a sliding angle of less than 10 degrees, along with 100% oil absorption properties. The modified surfaces were also found to be recyclable, with the ability to reload oil after burning and squeezing.

Summary: This study reports a surface-modified sponge material, prepared by simply mixing Poly[cyclo-triphosphazene-co-bisphenol AF] (PZAF) with the sponge, which can efficiently adsorb oil from water at room temperature. After 10 cycles of oil adsorption-desorption, the modified sponge still maintains a high adsorption capacity, indicating its good recyclability. The PZAF-modified sponge exhibits promising industrial potential in purifying oil-contaminated water, such as offshore oil spills and wastewater from oil and steel industries.

Summary: With the increase in antimicrobial-resistant bacteria strains, finding new and effective ways to reduce bacterial infection rates is crucial. Superhydrophobic materials exhibit unique wetting properties that can minimize bacterial attachment points, making them effective in reducing bacterial adhesion. This study investigates the impact of surface design on the anti-biofouling capabilities of superhydrophobic pillared arrays prepared via photolithography. By varying pillar spacing, insights into the complex nature of superhydrophobic fouling are gained, allowing for optimization of antifouling performance. The optimal material achieved a 3-log reduction in bacterial attachment (＞99.9%) at a pillar spacing of 87.5 μm.
