dc.description.abstract | According to the developed bioinspired method in the one-step procedure, the material with the petal effect was
switched to lotus one. Therefore, highly hydrophobic and super-hydrophobic materials with tunable adhesive
properties and fractal-like structures were successfully produced with high efficiency (67–84%). The work’s
essence was to modify chemically selected powders of lanthanide oxides (CeO2, Pr6O11, Nd2O3, and Gd2O3). High
effectiveness of the functionalization process with 1H,1H,2H,2H-perfluorooctyltriethoxysilane (FC6) and noctyltriethoxysilane
(C6) was proven by various techniques, e.g. XPS, HR-TEM, ATR, XRD, zeta potential. Materials
with water contact angle between 143.6◦ (CeO2-C6) and 175.5◦ (Nd2O3-FC6) with thermally stable
nanolayer (up to 380 ◦C) were generated. Surfaces functionalized with FC6 possessed a polar component of
surface free energy (SFE) close to zero. Water behavior in contact with the modified materials was studied, taking
into consideration the unique electron structure of lanthanides assessed by goniometric measurement, also
adhesion and spreading pressure were determined. Very low adhesion and polar SFE partly resulted in immediate
bouncing of water droplet upon contact with the modified surface. The presented method allows preparing stable
materials with a high potential in materials chemistry and modulation of surface features and engineering (e.g.
heat transfer fluids, specific coating). | pl_PL |
