Abstract:
Polyaniline (PANI) thin films have been shown an increased interest by the scientific community for their impressive proprieties such as conductivity, adhesion, chemical stability and ease of use. The use of iron oxide doped polyaniline (PANI) has numerous applications as anticorrosive layers, sensor sensitivity boost, or in biomedical applications such as hyperthermia cancer treatments, imaging or drug delivery. This work is focused on analysing proprieties of Fe2O3 doped PANI films obtained by DC plasma polymerization in a vacuum device called reactor. As described in some of our earlier work [1], the plasma polymerization reactor consists of a vacuum chamber, two inner electrodes and a sample holder. After achieving a base-pressure of 10-2torr, aniline mixed with Fe2O3 nanoparticles is injected inside the reactor through a hole in the anode (upper electrode) and a DC plasma is ignited. The polymerization process starts and a polyaniline film starts to grown on the substrate surface, embedding the iron oxide particles. The resulting thin films were viewed from a morphological point of view by SEM (Scanning Electron Microscope) and AFM (Atomic Force Microscopy). These analysis have shown a uniform distribution of particles on the surface and imbedded in the film, claims that are also supported by EDS (Electron Dispersion Spectroscopy) measurements. Furthermore, size distribution of Fe2O3particles range between 200nm and 3µm. FT-IR (Fourier Transform Infrared Spectroscopy) present some modification in the PANI spectra from obtaining a core-shell conformation.
