The contact angle measurements were performed with deionized water (2 μl) at room temperature (41) using a SL200KS contact angle meter (Kino) following the sessile drop method. Nanofiber coatings on diverse substrates were thoroughly washed with deionized water and dried with nitrogen gas. Samples were then placed on the analysis plane of the contact angle analyzer. The results were analyzed using One Attension software, and the drop shape was fitted using Young-Laplace method. The substrates without coatings were used as control. Data are presented in fig. S8C.
