Radiation-Chemical Modification of PVDF Films as a Method of Creating Proton-Conducting Membranes

Abstract:

In this work we represent the results for the development of proton conductive membranes by radiochemical modification of thin PVDF films with their subsequent sulfonation. Radiation source were ⁴He ions with energy of 27 MeV produced by cyclotron R-7M the FTI TPU. The results of IR-spectroscopy, gravimetric analysis and microscopy are represented to evaluate changes in membranes properties. It was shown that the deepness of modificated gel can be controlled by radiation.
