| In recent years, intrinsic electrically conductive (ICP) polymers have been studied because of their applications have demonstrated to be changed over the full range from an insulator to a metallic conductor. [1]. Polyaniline (PAni) is one of the most intensively investigated ICPs due to its environmental stability, low cost of raw materials and ease of synthesis [2]. However, as in other ICPs PAni is insoluble, infusible and almost non-processable, which makes difficult its potential application. Its properties such as processability, solubility, spectroscopic and electrochromic properties, can be modified and improved by suggested methods [3,4,5]. In the presented work was aimed to obtain copolymers of Polyaniline with the maintanence of the electrical conductivity in its thin films. Firstly, styrene sulfonate of PAni (PAni-SSA) synthesis, via oxidative polymerization pathway, and secondly, the synthesis of the graft copolymers of PAni, were studied. The morphology of PAni-SSA and the three copolymers was characterized by Scanning Electron Microscopy (SEM) for studies. Synthetization of PAni-SSA and graft copolymers of PAni-SSA by free radical pathway through emulsion polymerization technique, permitted to achieve the particle size ~30 nm. The thickness of the films which were deposited on to glass slides were also measured by SEM by inclining them 45 °. As seen in Fig. 1 the materials were deposited on the glass slides in nanometric thickness. | |
