Preparation of Fluorine-Free and Durable Water-Repellent Textiles
In this study, researchers presents a facile approach for the synthesis of a water-repellent emulsion by copolymerization of bis-vinyl capped siloxane and stearyl acrylate. The emulsion was applied to cotton via a simple dip-pad-cure process, achieving a durable superhydrophobic fabric.

Laser-enabled organic coating for sustainable PFAS-free metal surfaces
This study presents a laser-enabled organic coating (LASEO) approach that integrates laser texturing with gel-like carbon dot (G-CD) treatment to develop a PFAS-free alternative for metal surfaces. In this method, nanosecond laser-induced micro/nanostructures enhance coating adhesion, while the G-CD coating provides durable superhydrophilicity and even superwicking behavior.

Planarity Is Not Plain: Closed- vs Open-Shell Reactivity of a Structurally Constrained, Doubly Reduced Arylborane toward Fluorobenzenes
Through experimental and quantum-chemical studies, researchers unveiled the underlying reaction mechanisms and show that Li2[1] acts either as a B-centered nucleophile in an SNAr-type conversion (low benzene fluorination) or as a reducing agent in a single-electron transfer/H atom abstraction sequence (high benzene fluorination).

Facile fabrication of eco-friendly flame retardant and superhydrophobic coatings on cotton fabrics
To address the challenge of the durability of eco-friendly flame retardants coated on fabric surfaces, a coating (SFR) on cotton fabrics combining superhydrophobic, environmentally-benign, durable flame-retardant properties was prepared through sequential dip-coating of ammonium phytate (AP) and N-dodecyltrimethoxysilane-modified mesoporous silica nanoparticles (D-MSNs), assisted by polydimethylsiloxane (PDMS) adhesive.
A design of fluorine-free coating for durable amphiphobic fabric
In this work, researchers present a novel fluorine-free amphiphobic fabric, featuring a hierarchical surface architecture comprising silica gel particles and a specially designed polymer coating.
Phosphate-enabled mechanochemical PFAS destruction for fluoride reuse
Here researchers disclose a protocol that converts multiple classes of PFAS, including the fluoroplastics polytetrafluoroethylene and polyvinylidene fluoride, into high-value fluorochemicals. To achieve this, PFASs were reacted with potassium phosphate salts under solvent-free mechanochemical conditions, a mineralization process enabling fluorine recovery as KF and K2PO3F for fluorination chemistry.
Biobased Hydrophobic Solutions for Natural Textiles—Moving Beyond PFAS
PFAS are widely used in textiles for their hydrophobic properties but pose environmental risks due to their persistence and toxicity. This review explores natural-based hydrophobic coatings, such as waxes, fatty acids, and natural polymers, assessing their potential as sustainable PFAS alternatives.
