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 face centered cubic (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 behavior.

自组装聚苯乙烯球的等离子体功能化对松木的超亲水涂层

通常用于胶体光刻的自组装膜已应用于松木基材上，以改变其表面润湿性。因此，单分散聚苯乙烯（PS）球已通过浸涂法沉积在粗糙的松木基材上。所得的PS球膜类似于多晶面心立方（FCC）状结构，典型域尺寸为5–15个单球。该自组装涂层通过O ₂等离子体进一步功能化。这种等离子体处理极大地影响了最外层的粒径，并且将羟基以及羰基引入了PS球的表面，从而产生了超亲水行为。
