CONTROLLED PHASE SEPARATION IN CONJUGATED POLYMER BLENDS INDUCED BY THERMOLITHOGRAPHY

The big interest in conjugated polymers is due to their easy solution processability, which endows them with several prospects, from low-cost processing, to opportunity of creating materials with new properties by simple mixing solutions, so research has focused on to optimize the blends properties in order to enhance optoelectronic device performance. Possibility to rules a phase separation in conjugated polymer blends has wide range of applications in optoelectronics, because both charge transport and charge separation are influenced by presence of phase segregation. Here we present a new method of controlling phase segregation in conjugated polymer blends by using a scanning probe microscope.
