Green synthesis of superhydrophobic cotton filters using Pistacia atlantica gum for efficient oil and water separation

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: April 4, 2025

In this study, a novel hydrophobic polysulfide (NPS) reagent was synthesized using Pistacia atlantica gum and sulfur powder under hydrothermal conditions. Boehmite (γ-AlOOH) functionalized with curcumin (BCur) TiO2 nanoparticles were coated the NPS reagent. Subsequently, cotton fabrics dip-coated separately NPS, NPS-BCur, NPS-TiO2, resulting in fabrication of superhydrophobic filters water contact angles (WCA) exceeding 150°. The reagents thoroughly characterized FT-IR, XRD, TGA, SEM, X-ray mapping, WCA measurements. demonstrated exceptional performance separating oil-water mixtures, achieving separation efficiencies 91-98.6%. Even after 20 recycling cycles, negligible changes observed efficiency. use natural materials, eco-friendly synthesis, high durability, outstanding underscore sustainability practicality these fabrics.

Multifunctional Flexible Hard Coatings with Weathering Resistance and Heat-Shielding Properties

Polymers, Journal Year: 2025, Volume and Issue: 17(4), P. 519 - 519

Published: Feb. 17, 2025

Hard, flexible, transparent, and hydrophobic multifunctional coatings have a wide range of applications, but they do not adequately protect against harsh conditions, especially photoaging. In this study, SiO2 Al2O3 nanoparticles were first modified by silazane epoxy-functionalized silanes then reacted with polyetheramine curing agent to prepare highly crosslinked hybrid at room temperature. Due the integration siloxane polymer network, presented outstanding hardness (4H), flexibility (bending diameter 10 mm), transmittance (>97%). The introduction low-surface-energy PDMS methyl-rich HMDS endowed good hydrophobicity (water contact angle = 141.37°). high reflectivity in solar spectral region can help prevent photoaging coatings, improve their heat-shielding effect, broaden application scenarios. Compared traditional manufacturing methods, study did need ultraviolet irradiation, transparent could be prepared through simple efficient step-by-step strategy.

A Superhydrophobic and Recyclable Coating with Strong Robustness for Anti‐Icing Applications

Advanced Materials Technologies, Journal Year: 2025, Volume and Issue: unknown

Published: March 6, 2025

Abstract Conventional superhydrophobic coatings frequently incorporate thermosetting resins as substrates, which are challenging to recycle. This study explores the application of ester‐exchange degradable 4,5‐Epoxyhexane‐1,2‐dicarboxylic glycidyl ester (DGEAC) combined with structurally engineered and perfluorooctyltriethoxysilane (POTS) modified carbon black@silica (CB@SiO 2 ‐POTS) particles fabricate recyclable (DGEAC/CB@SiO using a non‐solvent‐induced phase separation technique. The resulting display properties, contact angle reaching 162.2° ± 1°. surface exhibits three‐tier hierarchical micron/micron/nanostructure, imparting remarkable stability coating retains its superhydrophobicity after 4000 cm abrasion 800‐grit sandpaper under 5 kPa pressure. Furthermore, demonstrates excellent icing delay performance (600 s) minimal ice adhesion strength (25.7 kPa), along rapid photothermal de‐icing capability (120 s). polyester in is rapidly degraded within 24 h presence ethylene glycol, facilitates release hydrophobic particles. By filtering out (DGEAC), CB@SiO ‐POTS successfully recovered. coating, re‐prepared from collected raw materials, maintained over five recycling cycles. straightforward approach fabricating notable environmental compatibility offers promising reference for advancing recyclability coatings.
