Low‐Cost and Scaled‐Up Production of Fluorine‐Free, Substrate‐Independent, Large‐Area Superhydrophobic Coatings Based on Hydroxyapatite Nanowire Bundles

To date, the scaled‐up production and large‐area applications of superhydrophobic coatings are limited because of complicated procedures, environmentally harmful fluorinated compounds, restrictive substrates, expensive equipment, and raw materials usually involved in the fabrication process. Herein, the facile, low‐cost, and green production of superhydrophobic coatings based on hydroxyapatite nanowire bundles (HNBs) is reported. Hydrophobic...
