Polyaniline – Fe2O3 and polyaniline – MgFe2O4 composites were prepared by in – situ polymerization of aniline in the presence of oxides particles. The resulted composites were characterized by Fourier transform infrared spectra, scanning electron microscopy, particle sise distribution, and thermal analysis and sensing measurements. It has been found that the introduction of conducting polyaniline not only improved the conductivity of iron oxides particles, but also improved the dispersibility of ferrites. Polyaniline iron oxides composites are the most sensitive to acetone vapors and can be used as gas sensor. The higher value of specific surface of composites and a strong interaction between the polyaniline and ferrites particles can explain the sensitivity values obtained for composites samples..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
