Superhydrophilic coating of pine wood by plasma functionalization of self-assembled polystyrene spheresDahle, Sebastian (Avtor) Meuthen, John (Avtor) Gustus, René (Avtor) Prowald, Alexandra (Avtor) Viöl, Wolfgang (Avtor) Maus-Friedrichs, Wolfgang (Avtor) X-ray photoelectron spectroscopyatomic force microscopyconfocal laser scanning microscopyscanning electron microscopySelf-assembling films typically used for colloidal lithography have been applied to pine wood substrates to change the surface wettability. Therefore, monodisperse polystyrene (PS) spheres have been deposited onto a rough pine wood substrate via dip coating. The resulting PS sphere film resembled a polycrystalline face centered cubic (FCC)-like structure with typical domain sizes of 5-15 single spheres. This self-assembled coating was further functionalized via an O$_2$ plasma. This plasma treatment strongly influenced the particle sizes in the outermost layer, and hydroxyl as well as carbonyl groups were introduced to the PS spheres' surfaces, thus generating a superhydrophilic behavior.20212022-02-11 10:08:47Članek v reviji134924sl
