Tailoring the physical properties of poly(3-Hexylthiophene) thin films using electro-spray deposition

Structural and electronic properties of homogeneous poly(3-Hexylthiophene) (P3HT) films ob- tained from the electro-spray method were presented by means of grazing incidence x-ray diffrac- tion, atomic force microscopy, optical absorption, photoelectron spectroscopy and (photo)electrical conductivity. Different structural conformations were obtained starting from different solution con- centrations and flow rate conditions. The electro-spray method was shown to effectively expand the control of the conformation and assembling of the polymers films, opening the way to the possibility of tailoring film characteristics according to device specifications.
