dc.description.abstract | Novel polyelectrolyte membranes were prepared from pure solutions of alginate (Alg), carrageenan (Car) and their mixtures. The films were crosslinked and sulfonated and then, characterized by several techniques: ionic exchange capacity (IEC), water uptake, mechanical thermal properties, and also functional properties such as methanol permeability and proton conductivity. The results show that Alg/ Car membranes have a ductile behavior. Low carrageenan concentrations have a weak thermoprotective effect, which slightly delays both T-g and T-m of prepared membranes. The methanol permeability of Alg/ Car membranes increase with the carrageenan content varying from 0.55 x 10-6 cm(2) s(-1) for Alg/Car 100/ 00 to 4.89 x. 10-6 cm(2) s(-1) for Alg/Car 80/20. The Proton conductivities of the membranes increase with the carrageenan content from 9.79 x 10(-3) S cm(-1) for Alg/Car 100/00 until 3.16 x 10(-2) S cm(-1) for Alg/Car 80/20 at 90 degrees C. Finally the proton transfer mechanism is discussed in terms of the conductivity activation energy and the dependence of the proton diffusion coefficient with the temperature has been studied. | es_ES |
