Two methods have been developed for nanotechnology: spin coating and water casting. Spin coating technique is an excellent method of producing plastic thin films. The thin films are prepared by spin coating from a toluene solution and the thickness can be varied by adjusting either the spinning speed or the concentration of the solution. Typical solution concentrations are 1-3% with spin speeds between 1 K and 5 K rpm. Water casting method, on the other hand, involves placing drops of 2% diblock solution in toluene on the surface of the deionized water, after which toluene evaporation occurs, leaving plastic thin films on the surface.
