Comparison of different self-assembly methods for formation of a homogenous monolayer of polystyrene

Abstract In this paper, we report on the formation of nanomasks by polystirene (PS) spheres as small as 150 nm in diameter using different self-assembly methods. Spin coating method was the most efficient. The influence of spin speeds, spinning time, solution quantity is studied in order to achieve a large area close-packed monolayer. A relatively high surface coverage and uniform monolayer of PS spheres can be achieved by appropriate control of the preparative parameters. It can be useful in industrial applications, because of the fabrication speed, surface coverage, control over PS spheres and cost of the process.
