However, many industries interested in the application of hydrophobic properties are yet to find a suitable solution to their needs. This paper looks at the rapid functionalization of nanoparticles and the fabrication of superhydrophobic surfaces with contact angles > 170°. This was achieved by simply mixing commercial products and applying the new formulation with scalable techniques. First, inexpensive and nontoxic superhydrophobic nanoparticles were made by functionalizing nanoparticles with fatty acids in under an hour. A similar methodology was then used to functionalize a commercial polymer coating to express superhydrophobic properties on it by lowering the coating’s surface energy. The coating was then applied to a surface by the spray technique to allow for the formation of hierarchical surface structures. By combining the low surface energy with the necessary roughness, the surface was able to express superhydrophobic properties. Both the particles and the surfaces then underwent characterization and functional testing, which, among other things, allowed for clear differentiation between the functionalization properties of the zinc oxide (ZnO) and the silica (SiO2) nanoparticles. This paper shows that suitable superhydrophobic solutions may be found by simple additions to already optimized commercial products. date: 2024-02-02 date_type: published publisher: American Chemical Society (ACS) official_url: http://dx.doi.org/10.1021/acsomega.3c09123 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2233579 doi: 10.1021/acsomega.3c09123 lyricists_name: Reyes, Cesar lyricists_name: Parkin, Ivan lyricists_name: Carmalt, Claire lyricists_name: Cassidy, Sam lyricists_id: CIREY84 lyricists_id: IPPAR53 lyricists_id: CJCAR00 lyricists_id: SCASS91 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner full_text_status: public publication: ACS Omega issn: 2470-1343 citation: Cassidy, Sam S; Page, Kristopher; Reyes, Cesar III De Leon; Allan, Elaine; Parkin, Ivan P; Carmalt, Claire J; (2024) Modification of Commercial Polymer Coatings for Superhydrophobic Applications.
