“…It is has been widely accepted that Nafion is the widely used ion exchange membrane in fuel cell industry, But these membranes are expensive and has its own limitations in terms of porosity and gas diffusion. [4,5] The polymer studied in this work was the high impact polystyrene (HIPS), a thermoplastic with melting temperature of 240 C, and possess excellent chemical resistance [5,6]. Polyaniline (PAni) and other conducting polymers are used in the membranes production because they present ion exchange characteristics.…”

Over the past decade or so, alternative energy plays a pivotal role in addressing challenges posed by nature. Polymer electrolyte membrane fuel cell is one of the promising alternative energy and there has been significant research and technological investments done in this field. The key information and future prospective of the field is energy conversion and storage, both of which are essential in order to meet the challenges of global warming and the limited fossil fuel supply. However, polymer membrane in particular plays a crucial role in advancing this technology further. The utilization of conducting polymers in manufacturing membranes combining their electrochemical properties along with mechanical properties is of primary importance to enhance the efficiency of this system. In the present study blends of high impact polystyrene (HIPS) and polyaniline (PAni) were obtained with the aim of producing membranes for fuel cell. HIPS and PAni were dissolved in tetrachloroethylene, a common solvent for both materials. After dissolution, PAni was dispersed in an HIPS polymeric matrix. The membranes were molded on to glass plates using a laminator to keep thickness constant, and the solvent evaporated slowly for 24 h under room temperature. The amount of polyaniline used was 10 and 20 % weight. The electronic and structural properties were carried out using X-ray photoelectron spectroscopy (XPS), Thermogravimetric Analysis (TGA) Raman spectroscopy, Scanning electronic microscopic (SEM). The analysis indicate that PAni incorporation and its dispersion into the polymeric matrix modifies the membranes properties and show improvement in efficiency.

“…Within this field, some of us have prepared and examined the performance of cationic membranes made of PAni composited with high-impact polysterene (HIPS/PAni) for the treatment of zinc solutions, which is frequently present in industrial effluents. [15][16][17] HIPS was used to impart mechanical resistance to the membrane since the mechanical properties of PAni are very poor.…”

“…15,16 The swelling and ion-exchange capacities, chemical stability, electrical conductivity, thermal behavior, and electrodialysis were determined for the produced membranes. Results indicated that membranes in which PAni was doped with CSA and TSA present good Zn 2+ transport as well as percent extraction compared to the commercial membrane Nafion 450, while the membrane with DBSA has a low transport number of Zn 2+ ions.…”

The extraction of Na + , Ni 2+ , and Cr 3+ using six different membranes made of polyaniline composited with high-impact polystyrene, which differ in the doping agent and/or the preparation method, has been investigated. The swelling and ion-exchange capacities of the six polyaniline composited with high-impact polysterene (HIPS/PAni) membranes have been determined and compared with that of the commercial Selemion membrane. Electrodialysis tests using a five-compartment cell evidenced that the extraction of ions depends on the electronic structure of the SO 3 -groups, which is modulated by the doping agent, and on both microstructure and electrical resistance of the membrane, which are regulated by the preparation method. The transport of ions through HIPS/PAni and Selemion membranes was found to be comparable. Quantum mechanical calculations on model complexes have been performed to characterize the electronic structure of the dopants. Results indicate that the strength of the interaction between the different doping agents and the polyaniline is inversely proportional to the concentration of negative charge in the SO 3 -group of the former. Moreover, both the binding energy and the distribution of charges calculated for dopant · · · PAni complexes have been compared with those predicted for dopant · · · metallic ion complexes.
