Novel anion exchange membranes were synthesized by grafted copolymerization of 1-vinylimidazole onto pre-irradiated ethylene-tetrafluoroethylene copolymer (ETFE) film, followed by quaternization and alkalization. The structure of the membranes was studied by Fourier transform infrared (FT-IR). The physicochemical and electrochemical properties of the membranes were also characterized. The ionic conductivity of the synthesized membrane is 0.03 S/cm at 30°C. This result indicates that the membrane is suitable polymer electrolyte membrane and so may find potential applications in alkaline membrane fuel cells.

AbstractNormally polymer electrolyte membranes are prepared and studied for applications in electrochemical devices. In this work, polymer electrolyte membranes have been used as the media to culture fractals. In order to simulate the growth patterns and stages of the fractals, a model has been identified based on the Brownian motion theory. A computer coding has been developed for the model to simulate and visualize the fractal growth. This computer program has been successful in simulating the growth of the fractal and in calculating the fractal dimension of each of the simulated fractal patterns. The fractal dimensions of the simulated fractals are comparable with the values obtained in the original fractals observed in the polymer electrolyte membrane. This indicates that the model developed in the present work is within acceptable conformity with the original fractal.
