Paper Title:
A Novel Method to Prepare Nano-Structured Semi-Conducting Polythiophenes by Supercritical Process
  Abstract

Rapid Expansion of Supercritical carbon dioxide Solutions (RESS) containing CO2-soluble, fluorinated ester substituted polythiophene: poly[2-(3-thienyl)acetyl ,3,4,4,5,5,6,6- 7,7,8,8,8,tridecafluoro-1-octanate] (PSFTE) through a small heated micro-orifice (150 .m) produces nanoparticles in the size range of 50 - 300 nm. Pre-expansion temperatures and pressures were found to have marked impact on particle size and morphology. While the particle size increased with more agglomeration with increase in temperature, smaller and spherical particles were produced with increase in pressure owing to the higher solubility of PSFTE in CO2 at high pressures.
