Presentation Title SPU-9:Mechanochemistry for Creation of Functional Surface Treatments

On-Site Speaker (Planned) Jennifer Johnson
Abstract Scope This research explores mechanochemistry to create functional surface treatments. A planetary centrifugal mixer was used to modify fluorite (CaF2) and BAM particles (Aluminum Magnesium Boride, Al3Mg3B56) surfaces. BAM and fluorite particles were treated with oleic acid to increase hydrophobicity. The particles were evaluated using Fourier transform infrared spectroscopy (FTIR) and contact angle goniometry to determine the effectiveness of mixing and possible reactivity. Contact angle measurements revealed that the fluorite particles turned from hydrophilic to hydrophobic with a contact angle of 150 when treated with low amounts of oleic acid. FTIR spectroscopy revealed a chemisorbed calcium oleate on fluorite while oleic acid with boric acid present for BAM. The mechanochemical process is successful in transforming surface properties without the use of water or heat and holds promise for surface engineering in areas of mineral processing, and additive manufacturing.
