Raw and analyzed data for manuscript: "Superhydrophilic coating of pine wood by plasma functionalization of self-assembled polystyrene spheres"

<strong>Abstract: </strong> Self-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 FCC-like structure with typical domain sizes of 5 – 15 single spheres. This self-assembled coating was further functionalized via an O₂ 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 behaviour.**摘要：** 本研究将通常用于胶体光刻（colloidal lithography）的自组装薄膜应用于松木基材，以调控其表面润湿性。为此，通过浸涂法（dip coating）将单分散聚苯乙烯（polystyrene, PS）微球沉积至粗糙松木基材表面。所得PS微球薄膜呈现类多晶面心立方（face-centered cubic, FCC）结构，其典型畴区尺寸为5~15个单颗微球。该自组装涂层可通过氧气等离子体（oxygen plasma, O₂）进一步实现功能化改性。该等离子体处理对最外层微球的粒径具有显著影响，同时在PS微球表面引入了羟基与羰基基团，最终使基材获得超亲水（superhydrophilic）性能。
