“…A superhydrophobic surface refers to a surface with a static water contact angle (WCA) greater than 150° and contact angle hysteresis (the difference between advancing and receding contact angle, θ Hys ) less than 10°, [ 1,2 ] having attracted tremendous attention from both academia and industrial fields over the past decades, because of their potential applications [ 3 ] ranging from self‐cleaning surfaces, [ 4,5 ] oil–water separation, [ 6,7 ] waterproof textiles, [ 8,9 ] to biotechnology. [ 10 ] The wetting behavior of a solid surface is typically governed by two vital factors – chemical composition and surface topography.…”

Superhydrophobic surfaces based on non‐fluorinated materials and facile fabrication techniques are of great practical value with respect to environmental friendliness and industrial applications. In this work, a fluorine‐free, superhydrophobic coating with hierarchical surface structure and low surface energy is successfully fabricated on various substrates through a recently developed dip coating combined with non‐solvent induced phase separation (dip‐coating‐NIPS) method. A bio‐based polymer, poly(l‐lactic acid), and commercially available hydrophobic SiO2 nanoparticles, are used. The fabricated coating exhibits superhydrophobicity, with a static water contact angle (WCA) of 155.7° ± 1.4° and contact angle hysteresis (θHys) of 5.2° ± 0.4°. The results from stability tests demonstrate excellent mechanical durability and chemical stability of the superhydrophobic coating. Finally, the fabricated coating is successfully applied in water–oil separation with superior efficiency. This simple, cost‐effective, and time‐efficient method may provide an effective way for the design of nonfluorine‐based environmentally friendly membranes for separation applications.

“…An ideal wound dressing should be nontoxic, nonallergenic, nonadherentto skin, and able to absorb excess exudates to maintain an ideal moist environment for the wound [ 4 ]. Further, an ideal would dressing should possess biocompatible and antimicrobial properties to enhance wound healing, as well as a self-cleaning ability to prevent contamination [ 8 , 9 ].…”

In wound care management, the prevention of wound infection and the retention of an appropriate level of moisture are two major challenges. Therefore, designing an excellent antibacterial hydrogel with a suitable water-adsorbing capacity is very important to improve the development of wound dressings. In this paper, a novel silver nanoparticles/poly (gamma-glutamic acid) (γ-PGA) composite dressing was prepared for biomedical applications. The promoted wound-healing ability of the hydrogels were systematically evaluated with the aim of attaining a novel and effective wound dressing. A diffusion study showed that hydrogels can continuously release antibacterial factors (Ag). Hydrogels contain a high percentage of water, providing an ideal moist environment for tissue regeneration, while also preventing contraction of the wound. Moreover, an in vivo, wound-healing model evaluation of artificial wounds in mice indicated that silver/γ-PGA hydrogels could significantly promote wound healing. Histological examination revealed that hydrogels can successfully help to reconstruct intact epidermis and collagen deposition during 14 days of impaired wound healing. Overall, this research could shed new light on the design of antibacterial silver/γ-PGA hydrogels with potential applications in wound dressing.

The prevention of refractory organic pollution caused by conventional dyeing and the development of new fabrics with various functions are two issues to be solved urgently in the field of textile fabrication. Here, we report a new environmentally friendly route for the simultaneous coloration and functionalization of textiles by the covalent immobilization of a metal–organic framework, Cr-based MIL-101(Cr), onto the surfaces of nylon fabrics by co-graft polymerization with 2-hydroxyethyl acrylate initiated by γ-ray irradiation. The Cr(III) clusters color the nylon fabric, and the color intensity varies with the MIL-101 content, providing a “green” textile coloration method that is different from conventional dyeing processes. An X-ray diffraction (XRD) analysis shows that the nanoporous structure of the original MIL-101 particles is retained during radiation-induced graft polymerization. Numerous nanopores are introduced onto the surface of the nylon fabric, which demonstrated better sustained-release-of-aroma performance versus pristine nylon fabric in tests. The modified fabrics exhibit laundering durability, with MIL-101 nanoparticles intact on the nylon surface after 30 h of dry cleaning.
