ACCELERATING. FOREVER CHEMICALS. ELIMINATION.

TORNADO project is moving to new PFAS-free coatings with water and oil repellence, following safe and environmentally friendly solutions.

The research team, from Universita Cattolica del Sacro Cuore, took soil samples from Vicenza to isolate and identify promising microorganisms that may be capable of degrading PFAS. They combined classical microbiology techniques for the isolation of bacteria of interest with metabarcoding, a molecular biology technique used to identify multiple species from a mixed DNA sample.

Researchers at Goethe University Frankfurt have developed a novel boron-based catalyst that degrades PFAS – so-called ‘forever chemicals’ – under mild conditions, offering a promising route to reducing environmental contamination from fluorinated substances.

Microban International, announced the launch of H?O Shield, a PFAS- and PFOS-free water-resistant finish portfolio for textiles. This technology represents Microban’s first expansion outside of its traditional antimicrobial and odor control offerings, marking a significant growth of its capabilities.

The invention provides a fluorine-free water-based matte UV coating, and a preparation method and application thereof. The fluorine-free water-based matte UV coating comprises fluorine-free silicon modified water-based acrylic resin, a photoinitiator A, a photoinitiator B, a substrate wetting agent, a leveling aid, a defoaming agent, wax modified matting powder, a water-based wax dispersion, a wear-resistant powder and a thickening agent. Aiming at the traditional water-based UV matte coating, the invention optimizes the formula system, and realizes the stain resistance, the high water contact angle and the smooth hand feeling under the double adverse conditions of thoroughly getting rid of fluorine-containing components and low glossiness. And by constructing a extinction powder content-glossiness-contact angle model, screening out proper extinction powder by using the model and adjusting the content, the extinction powder content is ensured not to be in a critical region when the proper glossiness is achieved, and a larger adjusting space is provided. The invention also provides a preparation method and application of the fluorine-free water-based matte UV coating.

The invention relates to a fluorine-free flame-retardant PC resin composition, and a preparation method and application thereof. The resin composition comprises, by weight, 85-92 parts of PC resin, 5-8 parts of phosphazene flame retardant, 2-4 parts of flexibilizer, 2-4 parts of fumed silica, 1-3 parts of multi-wall Carbon Nano Tube (CNT),

The application provides a fluorine-free oil-proof agent, a preparation method and application thereof, and belongs to the technical field of textile assistants. The fluorine-free oil-proof agent is prepared by reacting fluorine-free oleophobic monomers with hydrophobic silica aerogel particles, wherein the fluorine-free oleophobic monomers have umbrella-shaped liquid characteristics, and the hydrophobic silica aerogel particles have a three-dimensional porous network structure. The fluorine-free oil-proofing agent can endow fabrics with good oil-proofing effect.

This water repellant composition includes a non-fluorinated polymer (?) containing constituent units derived from a (meth)acrylic acid ester monomer (A1) represented by general formula (A-1) and constituent units derived from a compound (A2) represented by general formula (A-2), and a silicone resin (?). [In formula (A-1), R1 represents hydrogen or a methyl group, and R2 represents

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.

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.

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).

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.
