The root-mean-square (rms) roughness and the water contact angle values of untreated poly(3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12-heneicosaffluorododecyl acrylate) (PHFDA) film prepared on silicon substrate using spin-coating technique were about 1.35 nm and ?A/?R = 125o /103 o , respectively. On the other hand, the annealed film C and the freeze-dried film with only a small increase in the rms roughness and the water contact angle values were 2.05 nm and ?A/?R = 126o /111o , and 2.28 nm and ?A/?R = 130o /123 o , respectively. However, these values for the composite film composed of PHFDA and active carbon were 2.54 nm and ?A/?R = 165o /164o , respectively. This method can be applied to various surfaces as long as the composites composed of nanoparticles and polymeric materials do not cause any aggregation in spin-coatingeninfo:eu-repo/semantics/openAccessSuperhydrophobic SurfacesSurface RoughnessComposite FilmActive CarbonSpin-coatingArticle12422222610.25135/acg.oc.68.19.09.1403N/AQ3
