20.500.12556/DKUM-88548 Composite materials based on waste chicken feather fibers for oil-spill management Oil spills remain one of the greatest man-made ecological threats, despite numerous advanced cleanup approaches. They still pose a major challenge in the search for materials and technologies that work as efficiently and sustainably as possible. Promising natural materials include poultry feathers, which are produced in large quantities every day as a byproduct of the meat industry. In this study, the influence of different forms of absorbents (loose feathers, pillows, and sheets) based on chicken feathers and the addition of an inorganic absorbent, sepiolite, on their absorption capacity was investigated. The chemical and physical surface properties, like morphology, chemical composition, zeta potential, surface free energies and oil absorption capacities were analyzed. The Gibbs free energy of immersion wetting with oil and the work of adhesion of the adsorbents, calculated based on contact angle measurements, were confirmed by the tests of adsorption capacities according to the ASTM 726–12 standard. The results showed that pure loose feathers have the highest oil adsorption capacity, while feather pillows have only half, and composite sheets have only a quarter of this capacity. The addition of inorganic adsorbent sepiolite did not increase the absorption capacity of the composites. chicken feather fibers composites sepiolite surface properties oil adsorption oil-spill management vlakna piščančjega perja kompoziti sepiolit površinske lastnosti adsorpcija olja obvladovanje razlitja nafte true false true Taylor & Francis Angleški jezik Kitajski jezik https://www.tandfonline.com/journals/wjnf20 © 2024 The Author(s).
