Hot Wire Chemical Vapor Deposition as a Novel Synthetic Method for Electroactive Organic Thin Films

  • Gillian A. Zaharias (a1), Helen H. Shi (a1) and Stacey F. Bent (a1)

We are exploring the use of hot-wire chemical vapor deposition (HW-CVD) as an alternative, solvent-free technique to produce compact polyconjugated films from vaporized monomers. This paper will focus on our attempts to deposit polyaniline, a polymer with a wide variety of optoelectronic applications. Infrared and X-ray photoelectron spectra have been obtained to characterize HW-CVD films produced using aniline as a precursor. The aromatic ring structure, essential for the polyconjugated network that leads to semiconducting properties, is largely preserved in our method. The bonding structure is analyzed, and the films are found to have significant metal incorporated from the hot wire. The implications of these results for understanding the polymerization and growth mechanism are discussed.
