Patterned Domains of Polymer Blends

To produce electronic circuitries based on organic devices, it is also crucial to pattern the organic semiconductors on micrometer scale. Spin coating, as a deposition technique used to prepare uniform thin films, has been successfully implemented for the production of organic electronics. However, the films prepared by spin coating are always continuous and need to be patterned using other 

PQTTFTs measured under nitrogen flow (open triangles) and after exposure to air for 20 h (closed triangles), (b) Transfer characteristics 

In another work, Jaczewska [52] demonstrated that the strategy of pattern-induced self-organization is presented for the spin-cast polythiophene/polystyrene 

AFM image (20 nA z-scale). (f) Fluorescence image, (g) AFM height image of ISOnm diameter P3HT domains (2 nm z-scale) on smaller templates at lower P3HT concentration. (Reproduced with permission from Ref [50]. Copyright 2005, American Chemical Society.)
