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。
