Preparation of Waterbased Uv-Curable Superhydrophobic Polyurethane Coating

Herein, a simple, scalable, and cost-effective method was used to prepare superhydrophobic, sprayable fluorinated uv curable polyurethane-silica nanocomposite coating with promising physico-mechanical properties. through using this totally green method, coating with strong micro/nano-scale roughness structures, high contact angle (159.7˚), and low sliding angle (7.2˚) were obtained which can be applied onto different substrates. also, the exceptional durability of the fabricated coatings against sandpaper abrasion without losing the superhydrophobicity, revealed the high capability of the prepared waterborne coating to be used in harsh practical applications. moreover, the prepared coatings showed substantial potential for using in self-cleaning (in either air or oil environment) and oil/water separation fields. we are convinced that the prepared hybrid coating could offer a practical approach to construct various superhydrophobic materials as promising nominates for disparate fields.
