    These films were converted to epitaxial ?-quartz thanks to the inclusion of the salts in the silica matrix, which acted as melting agents. Epitaxy, and therefore piezoelectricity, was generated due to the mismatch with the crystalline silicon substrate. The crystallization behavior was then studied in block copolymer templated thin films and particles. A post-synthetic infiltration of alkaline ...

    The results indicate that only the redox behaviour of PVF films but also the film swelling is dependent on the nature and concentration of supporting electrolyte. The study of the break-in process revealed that significant accumulation of the solution species occurs in the neutral films. It was found that the degree of swelling depends also on the conditions of film preparation.
