Spin Coating For Fabrication Of (r) GO-Assisted Membranes

Spin coating method is a widely used method for the fabrication of (r) GO-assisted membranes. Commonly, the first step of spin coating is dropping GO suspension on a base. The second step is rotating the plate with high speed. Consequently, there will be a formation of thin liquid layer which is driven by a centrifugal force. The properties of different GO membranes prepared by three methods, spin-coating, drop-coating and solvent-induced precipitation. They used glass and quartz as substrate to fabricate GO films. As a result, the GO films fabricated by spin coating were the thinnest among all products.

Spin coating method can easily adjust the thickness and area of membranes by controlling the amount of (r) GO solution and the size of the substrate. The produced r-GO thin film have been used in the application of photodetection.
